Ask HN: What is it like to be old? What advice would you give to younger people?

247 pointsAnonHP301 comments

Older people can remember what it was like to be young. Younger people, on the other hand, cannot know first hand what it is to be or grow old. They can only see others around them and get some sense of the struggles, imagining themselves to be immune to those.

In your experience, what is it like to be or grow old (whatever your definition of old is) from the physical health aspect and the general frailty of the aging human body?

What are the health related struggles that have come into your life or have gotten worse because of increased age and how have you dealt with them?

With your experience and knowledge, what would you advise younger people (or even your own younger self of decades past, if you could)?

What's it like to be old?

My boss is younger than I am and is absolutely sure he knows more about my job than I do, even though I've been doing it since before he was born and he never did it at all.

People on TV keep trying to sell me stuff like Metamucil, some new kind of cane or similar silly gadget, or a scam investment, none of which I want.

My grandkids can't understand why I can't read things they're holding right in front of my face until I've spent twenty minutes finding, then cleaning, my glasses.

My wife has heard all of my jokes and all of my excuses. She now criticizes the former and laughs at the latter, instead of the other way around.

My friends sound like cranky old sticks-in-the-mud who wish they could turn back the clock to a time that wasn't nearly as wonderful as they claim to remember it was.

A trip to the supermarket now tires me out and instead of going out with (surviving) friends, I really look forward to taking a nap on the couch. Really.

The celebrities I recognize are senile and/or decrepit. The ones who are currently popular are appalling.

I don't have enough money to retire but dream of it every day (See the above comment about my boss).

Life is fantastic, except when it's not. Whichever it is now, pretty soon, it will be the other one.

My advice: Pay attention.

Out of all of them, this one rings the truest to me. Thank you! Other observations I've had as I get old:

The older I get the less it matters to me what other people think of me, which is liberating. When I was younger, people's impression of me was my problem. Now that I'm older, people's impression of me is their problem.

I always thought getting out-of-touch would be embarrassing, but it doesn't bother me at all. Pop culture is toxic.

I'm less interested in impressing people.

TV is marketed to a different demographic and appeals to me less and less as I age, which has freed up an enormous amount of wasted time.

I'm more and more suspicious of new products, not excited by them.

The older I get the more I value self-sufficiency and the less I believe in "we're all in it together".

Even though I try to stay tolerant, as I get older, the "woke overton window" moves faster than I can change my biases and prejudices. I can't keep up.

The thing that scares me the most about old age is that my health is going to hit a brick wall, and that I'm not taking good enough care of my body.

I'm most anxious/nervous about retirement: I think every day about retiring and exactly what I need to do and save to get there, and I wish thought about it that seriously in my 20s and 30s.

> The older I get the less it matters to me what other people think of me, which is liberating. When I was younger, people's impression of me was my problem. Now that I'm older, people's impression of me is their problem.

Same here. But to be fair, when I was younger, my future was uncertain. I wasn't sure what will happen 10 years later. Will I get a good job? Will I have a good relationship? Which skills will I gain, and which weaknesses will remain forever? With this much uncertainly, of course I was sensitive about other people's feedback -- even if in hindsight a lot of it was stupid.

Now... of course, anything can happen, and life can always change dramatically overnight... but I expect the following years to be mostly more of the same. And when people tell me what they think about me, I have more data about myself to judge whether their opinion makes sense. I also learned to recognize friends and avoid the rest of the world.

So it's not just me becoming wiser in this aspect; it's that my situation has actually changed to make this one aspect much easier.

Thank you for your post. I have a question, and I really don't intend to be mean spirited even though it may come across as such.

>I don't have enough money to retire but dream of it every day (See the above comment about my boss).

Software development (assuming you are are a developer) is a very well paid profession, and has been for many decades. This is the only profession where people who are 4 years out of school are often given 'senior', 'staff' titles, even at the most prestigious companies.

Have you been underpaid for a few decades or have you had some bad financial investments etc? Not sure if this is too personal but I was just curious.

Software development is only a well paid profession fairly recently, and only a very well paid profession if you are lucky.

I have been well paid (in the EU) since the early 90s in software dev.

Programmers have been well paid since at least the dot com bubble, that's a conservative 20 years, wouldn't consider that 'fairly recently' imo.

Also I would consider a bare six figure salary well paid.

Programmers have been well paid since at least the dot com bubble, that's a conservative 20 years, wouldn't consider that 'fairly recently' imo.

Outside of a few hotspots like Silicon Valley, programming salaries tend to ramp up quickly in the first few years then hit a plateau. Other professionals like lawyers, accountants, doctors start more slowly but their plateaus are much, much higher. This is why 25-year-old programmers think that they're rich. They haven't hit that plateau just yet, but most will, and sooner than they think. And not long after that they will have their first encounter with ageism. A lawyer or a doctor will never experience that, because his profession values experience. That is the hardest part of staying in this industry for decades, you get to see all your hard-won knowledge become worthless, for no reason other than fashions change.

The vast, vast majority of programmers aren't in tech firms, they are writing internal software for companies in other industries for whom software is a cost, not a profit centre. Those programmers are paid the same as any other mid-level office workers. These programmers are barely represented on sites like HN however so they are almost invisible.

Just to be more precise, programmers are well paid in USA, London and some other exception. In the rest of the world we are paid like any other "office job".

IF remote jobs and wfh culture will rise, I would bet those salaries are gonna plummet down in the medium term

>Programmers have been well paid since at least the dot com bubble, that's a conservative 20 years, wouldn't consider that 'fairly recently' imo.

That's because you're not very old yet.

I worked in state government in my past, and very few of the programmers there were making six figures.

Well paid != financially secure enough to never have to work again.

Yes, it's too personal a question. Also, your assumptions are overbroad.

I worked for a retail bank who had data that 50% of people earning up to around (I think) £70k had less than £100 in savings. Some people are very bad at saving, no matter how much they earn.

Nearly every accountancy firm or management consultant firm you can achieve senior associate within 4 years.

Can you please expand on that advice? What should we be paying attention to?

You're already getting the hang of it.

Just don't think about work, startups, money, etc when you are eating dinner with your family, or spending time with them. Harder than it sounds.

I had kids late in life, which I think has some advantages. One is that you've learnt that nothing lasts and it's important to be present in the moment, because it doesn't come back.

May I be so bold and ask what constitutes 'late in life' for you?

I like Dan Millman's lesson in a Peaceful Warrior

What time is it? Now Where are you? Here

I really like the scene in the movie where Socrates throws him off the bridge and Dan flips out and Socrates simply responds something along the lines "but while you were flying through the air your mind was completely focused on one thing. You even had a name for it: arghhhh!"

Man that book was epic when I discovered it all those years ago. Especially since I had a habit of visiting gas stations at odd hours of the night too.

Your teeth. Pay attention to your dental health.

I had mediocre dental care for most of my life. Not bad, but I never liked it. I got my first crown, was supposed to get two. It was traumatic. It didn’t feel good. I was depressed.

I found a dentist recommendation. Visited him, he looked at my teeth and said while it all met “the standard of care”, some of the old work would eventually need to be replaced, and the crown fit could be improved, and the other crown I needed could be replaced with an alternate procedure.

I got a good feeling from him. I spent the next 3 months having him re-do everything in my mouth. i was terrified and uncomfortable but I just went into it headlong. I was a bit flu$h, but it didn’t actually cost a lot.

It made all the difference in the world. My bite felt better. My teeth felt good. The tooth sensitivity to temperature vanished. I never think about My teeth anymore. They work, they are comfortable.

I think of myself as someone who is scared of dental visits. He cured me of that. I plan and attend each visit diligently.

I have a new dentist now.. I moved. I found someone I like. Understanding that my dental dissatisfaction was rooted in work that “met the standard of care” but which wasn’t satisfactory with each bite and sip I took was transformational.

I also floss diligently.

I asked a dental hygienist about this: "Why is there a focus on relaxed, spa-like dental practices? Who are these people who are scared of the dentist?"

She said it absolutely came down to past experiences. Apparently there are some really shitty dentists out there, in the sense of causing unpleasant experiences.

If you didn't get one of those as a child, you have no problem with visiting the dentist. If you did, dentists terrify you.

I never really thought about it that way before.

And sunscreen. Taking care of your skin (especially your face!) is one of the easiest passive ways to help yourself age gracefully.

Take care of the big 3: Dental, mental and genital.

Whatever advice an older person can give it is problematic in that it is only one point of view, and might be wholly inapplicable to your life given the fact you are a different person raised in different circumstances. You’d be hard pressed to find a counsellor having heard you rant for 100 hours give you advice. They only give you tools.

I’m older and I realise myself that I need advice, I’m not in need of giving it.

Coincidence - You weren't paying attention to the other half of what was going on - stand on Zanzibar

be conscious.

be mindful.

I'm 32 and already starting to feel this way.

I was reading the comment and was like, hey- I'm 39 and trips to the grocery store tire me out and I REALLY look forward to naps on the couch!

> trips to the grocery store tire me out and I REALLY look forward to naps on the couch!

Well, then, have I got a global pandemic (and societal consequences thereof) for you!

35er checking in

This advice is gold, thank you for sharing.

First, you'll probably never think of yourself as old. You'll look in the mirror and wonder why 20 year old you has all this gray hair and wrinkles.

Second, it's ok to let things slide for a while, but the longer you let them slide, the tougher they are to fix (and if you wait too long, some things can't be fixed). See plenty of other comments about teeth, back, RSI, diet. If you decide to let something go for a while, pick a time to follow up on it, and reevaluate.

Third, problems get bigger, stakes get higher. But you'll learn more tricks for coping with those problems. Sorta grim, but suicide rates by age climb till 50ish. around then you'll have (sorta) seen it all, there's not much that the world can throw at you that'll put you in a complete tailspin.

I can't tell you how to live your life. I'd suggest, be true to yourself, be true to your ethics. If you don't know what those are yet, try to figure out who you are. When you're stuck in a stressful situation, at the end do you want to feel vindicated? do you want to have a great outcome for everyone? do you want to just leave it all behind? Do you want to just grit your teeth and get through it? Those all point to different values, and can help you figure out who you are.

Some people age gracefully and some don't. some people get to make choices about that, and some don't. It's going to be ok. Everybody gets through their life one way or another.

> I'd suggest, be true to yourself, be true to your ethics.

This. You will forget the people who hurt you. But you will remember the people you hurt. You will accept the things you tried and failed. But you will regret not trying. Going against your ethics will leave scars on your soul, and the reasons for doing so will seem so stupid in hindsight.

But it takes some time to find your true ethics, and separate it from merely what other people say you should do.

> You will accept the things you tried and failed. But you will regret not trying.

This. It's not the first time I hear this advice, and even though I'm only 24 years old, I try to live by that.

> You will forget the people who hurt you. But you will remember the people you hurt.

Maya Angelou said this very well once:

> I've learned that people will forget what you said, people will forget what you did, but people will never forget how you made them feel.

I find this to be true and I also (try to) use it as a motivation to treat people better.

>You will forget the people who hurt you. But you will remember the people you hurt.

Could you elaborate on this? It seems like the exact opposite to me, I would more likely remember someone who hurt me than someone I've hurt, which in most cases I wouldn't even know I hurt them.

I meant only the things I am aware of. (And excluding the category of people who deserved it.)

Simply said, if someone hurts me, it means the person is an asshole. If I hurt someone, it means I am an asshole. The latter fact is more important to me, because a) I care about myself more than about other people, and b) I will have to live with myself for every day of my life, while other people will come and go.

Once I hurt a random bystander, because I wanted to fit with a group of cool kids, and they decided they didn't like his face. Yep. I am not the kind of person who does this often, and I would want so much to say that I am the kind of person who would never do it... but I lost the right to say those words since that day, irrevocably, forever.

And what did I gain in return? Pretty much nothing. It didn't win me a group of cool friends, mostly because those kids soon stopped being friends with each other, and some even turned into bitter enemies. Using the wisdom of hindsight, many of them were a lousy friend material in the first place. A few years later, life took us in different directions, and I haven't seen them since. These days, finding and contacting them using social networks would be trivial, but I just don't care anymore.

If I could turn back time and use the wisdom of hindsight, I wouldn't give a fuck about the cool kids, and would say "hello" to the stranger instead. And, who knows, there is a chance I would have found a good friend. -- But now, whenever I notice I betrayed my ideals again, I remember that day as the symbolic moment when I wandered off the path of righteousness.

Compared to this, situations when other people hurt me seem less important, often didn't have long-lasting consequences, and sometimes even turned into something good! For example, a girlfriend cheated on me with my friend, and a few other mutual friends knew about this, but no one said a word to me. Then I got some evidence, and after connecting the dots I realized they all have been making fun of me for quite some time, making hints to each other I didn't understand. That hurt!

So I broke contact with all of them, and drowned my sorrow in workaholism. A few years later, I had more money than most of my former friends combined. Then I burned out, so I decided to slow down and enjoy life again, made new friends (much better ones), and new girlfriends, and lived happily ever after. :) One day, I met my former friends, we had a beer in a pub, I watched them and listened to their stories, and realized they were a bunch of losers, and they unknowingly did me a great favor by preventing me from becoming one of them. Never met them again; don't care.

Which of these stories was better, speaking from a completely selfish perspective? The one where I hurt someone, or the one where I got hurt? And this is the lesson about ethics that young people sometimes don't get. Ethics is not merely another bullshit that adults tell you as a part of their neverending attempts to manipulate you. Strong internal ethics is the thing that allows you to navigate through hard times, and then look in the mirror and feel good about yourself (and have a story where you are the good guy). Lack of ethics makes you weak, and tempts you to sacrifice parts of your soul for things that will feel worthless much sooner than you can imagine at the moment.

How to build my ethics? Honest question, i have been clueless for a while.

This is something I worked on developing in my 20s. For me, what worked was finding an "ethical role model" -- someone who acts ethically and has a good sense of right & wrong -- and trying to model my choices based on what I thought that person would choose. Sometimes this would literally involve asking them "what do you think I should do?" and sometimes I'd just try to infer.

My ethical role model was my younger brother, who is one of the best people I know, and is someone who always seemed to have a good sense of "you shouldn't do that" or "this is the right thing to do, even if it's hard".

I committed to evaluating my decisions based on "what would my brother think of this" and I'm very proud to say that now, in my early 30s, I consider myself to be a very ethical person who does the right thing most of the time, even when it's inconvenient, and even when it's hard. I definitely could not have said that about myself a decade ago.

No idea if that will work for others, but it definitely worked for me!

How to build my ethics? Honest question, i have been clueless for a while.

Do you mean "how to I choose an ethical system to follow" or "how do I develop the strength of character to make hard choices"?

Read the biographies of people you admire.

I will agree that this is generally a good way to go, although in my experience there have been quite a few individuals that I end up no longer admiring.

I am 69, so I will chime in here: I now spend much more time dedicated to the food I eat, exercise, and meditation.

A good thing is that I mostly no longer care much about changing other people's opinions on things. I certainly enjoy talking and expressing myself but if someone listens to me then that is sufficient - they don't have to agree with me. It works the other way also: even if I disagree with someone, I can enjoy hearing what they say.

I retired 1 1/2 years ago and have been enjoying having lots of time to read, write books, spend time with friends and family, and hiking. That said, just yesterday I verbally agreed to a job offer for work that was just too interesting to pass up. Assuming that the employment contract looks good, then I am all-in.

My advice is to not worry about getting old, just make sure that you enjoy your life as much as possible. There are sayings about living life one day at a time, but that seems too coarse grained. I would suggest enjoying every minute of your life, and if you are not happy right now, this instant, then file a bug report with yourself. You can't do good work if you are not totally into the moment of what you are doing. You can't enjoy listening to someone if you are inside your own head and not giving that person your full attention. Play time and family/friend time are wasted if you are thinking about wanting to be doing something else.

Thanks for posing a good question.

Hi, thanks for sharing. This resonates.

What kind of books did you write?

Since Mark himself may not care to post this: https://markwatson.com/books/ .

Mostly AI, Lisp, etc.

regarding meditation, when did you start and are you doing it differently right now?

I started meditation in the mid 1970s, but this year started more formal training (a nine month set of lessons from the SRF). I probably devote about 30 minutes a day to meditation.

Physically, my best advice is to take good care of your back and your teeth.

These 2 things can make a huge quality of life difference once you are past 40. I would also add your eyes, but there is not a lot you can do about that one! Almost everyone needs reading glasses by 40. Glasses suck, but you get used to it.

Psychologically, the best I can say is to forgive yourself for any stupid things you did when you were young. Try to be as kind to yourself as you would be to others. I think of this as the "inverse golden rule." Really important as you get older, because regrets and self-doubt pile up otherwise.

One thing I'll add to this is to take care of your hearing. Some age-related hearing loss is inevitable, but you can reduce the amount of hearing loss you'll experience by minimizing your exposure to loud sounds.

How loud is too loud? A rule of thumb is that if you walk around with earbuds and can clearly hear a podcast while standing next to a busy street, it is loud enough to damage your hearing.

Hearing loss is a risk factor for dementia. As people lose their hearing it becomes harder to engage with their friends and family which speeds cognitive decline.

And don’t be afraid to wear earplugs. I used to commute via public transit with 25db earplugs in, to protect my hearing. It reduced my stress significantly to boot.

Would you mind to recommend a particular one to buy?

Not in particular. Earplugs are well regulated by the dB reduction they offer, the only other thing that matters is going to be fit, which is extremely personal. I’d recommend going with cheap disposable ones, since they tend to get pretty gross easily.

Active noise cancelling is great to be able to hear a podcast (or whatever else) where it's noisy without having to increase volume.

I agree and think q-tip use has damaged my hearing considerably over the years.

The ear canal is surprisingly delicate. I started ocean swimming recently, and was surprised to learn that I was developing "surfer's ear" -- a buildup of scar tissue. The damage is cumulative, and if you let it go past a certain point the only fix is surgery.

The sea water was causing scar tissue? I’m confused.

Almost everyone needs reading glasses by 40.

Not if these eye drops can help it!

http://fdaaa.trialstracker.net/trial/NCT03809611/

Thank you for posting. This compound to soften the solidified lens is a good idea.

My eye doctor told me something very useful about 20 years ago, when I was in my early 20s.

He told me not to wear my glasses unless I had a headache. He said that your eye has muscles and they need workouts like the rest of your body. So I basically never wore them.

I was just on the cusp of needing a prescription back then. He gave me glasses because insurance covered it so why not he said. But then gave me the advice above.

I’m 43 now and can see just fine without glasses. My prescription has been stable for 20 years.

I'm not certain that's sound medical advice (in fact, my intuition leans on it being bad advice)

Not wearing your glasses is a terrible idea if you have astigma (eye ball deformation).

If I let my eye muscles work, my vision would actively deteriorate.

Found a 20 year old copy of my first prescription.

Identical to my non prism glasses.

My advice, if your head hurts, there is a reason for it. And it probably matters.

your day will likely come, unless you're a -2.50 or so. you can almost figure out a person's age by their ability to accommodate (vary focus)-- there are graphs out there (https://qa.healthtopquestions.com/41365/presbyopia-age-chart). You may have a longer go w/o readers if your starting point is a little more minus. You should wear your glasses if you need them-- fatigued, unable to see, need to see. Nothing permanently bad happens if you wear them all the time or not at all, you'll just be blurry or strained.

That's a good way to get a headache that never goes away. Be careful.

Agreed on all accounts. Fighting your teeth, back, and weight sucks. You can't undo the damage of neglect to your teeth

I'm the opposite, I have increasingly failing sight long distance but my shortsightedness has no signs of showing. I'm curious when I'll need bifocals, and whether it's possible to wear long and short vision contacts, one in eye, and wait for my brain to adjust.

You must be myopic, and your optimal distance of your optical system is naturally at near. If so you may not need bifocals at all. Think of your distance glasses power as making up for how much your optical system is off by to be focused at infinity (distance). A person with a minus prescription has excess power and naturally focuses nearer targets. A person with -2.00 power glasses is focused best at 1/2.00 = 0.5m which is a nice reading distance. A person not requiring glasses ("0") is focused at infinity and has perfect distance vision. For such an eye to focus up close the lens/ eye muscles work to increase the power (fatten the lens) until near is in focus. Unfortunately this ability to accommodate steadily decreases w/ age, noticeable at 40yrs old. Those who are +3, the focal length is 1/3meters BEHIND your eyeball and you'll need glasses for everything once your natural ability to vary focus starts dropping off. You can figure out your exact focal length (meters) by taking your distance prescription a + b x c, and calc 1/(a + 1/2b). minus in front of eye, plus behind the eyeball. Neat, huh?

'Almost everyone needs reading glasses by 40'

I think it's more like 45 than 40.

I'm 45 this year. Bought my readers this year. Checks out.

I remember when I was a teenager and wondering what life would be like at 50. Now I know.

You feel exactly the same, only with less time left. You're still you. You still feel the same. You still want to experience all the same things and achieve. But now with less time, you have to start triaging some goals and face reality.

I remember thinking I have all the time in the world. Now I don't. So I guess that's the main difference.

Also, I used to hold the illusion that I'd always have my family and parents to talk to. But that's not true either.

> Also, I used to hold the illusion that I'd always have my family and parents to talk to. But that's not true either.

This. I used to think that way, then I lost my dad from cancer on my 20's. That's when you reflect on all the things you'll never be able to experience together.

Although I'm only 24 and still young, my piece of advice would be to enjoy your family to the fullest, because no one knows what tomorrow will bring.

Not quite the same. Everything hurts more and used up a larger share of energy.

Oh man, I never want to lose my mom

The alternative is worse.

That was me a 1 or 2 years ago, and I'm only in my mid 20s.

Just the realization that life is not limitless

Don’t give too much of your life to trying to control (ie politics, other people...).

How to do this is of course hard. Meditation helps me. Relationships. Balancing my consumption of news. Staying away from histrionic people that drive that anxiety (read Twitter). Taking a break from that which bothers me (developing hobbies and other interests).

Even as I get older I increasingly have a sense that all attempts to control will be resisted by others. Even when you have their best interests at heart. People willfully, sometimes ignorantly make their own big mistakes to resist being controlled. Sometimes though we’re not as smart as we think we are. This applies to so many situations, including work, politics, and parenting!

In work situations I am conscious more and more of wanting to lead by following, stepping back, let other people be in charge and get the glory. It’s really the most sustainable path for a sane life. Instead of doing, teach. Instead of teach, listen to other people’s wisdom. Paradoxically by being silent and non-action can sometimes have the biggest impact.

“Paradoxically by being silent I have the biggest impact.”

The impact may not always be positive. In some cases you are uniquely situated to lead, and by turning the opportunity down you create a vacuum for a less savory character to take place and inflict pain onto others.

This is true, though in many cases it's like 80-90% lead by following (w/ great people). 10-20% have a deft touch and show/create vision out of the team's raw material of ideas and inspiration

The twitter & politics seem so true. This is a little goofy but I’ve gone to lengths like journaling my mood to “prove” the wisdom of this for me, but old habits yadda yadda. Do you remember any kind of “inflection point”, was it a habit you broke or a natural proclivity or “aha” moment? I’m interested in the sausage-making of how people acquire this wisdom :-).

The 2016 US election and me pouring endless energy into Twitter arguments with Trump supporters.

Eventually too I read a lot of History about divisive times, and it showed me a lot of tragedy, much worse than what we're experiencing now. But also bounce back from that tragedy. You learn through life (and History) that Politics is relentlessly cyclical. Those that attempt control, even well intentioned, are ultimately resisted and replaced by the next regime that tries to take control, on and on...

That's not to say I don't vote. And I think you could meaningfully participate in the Political process out of a sense of duty or service. Like actually volunteering for a cause, etc you believe in. But don't waste your precious time on Twitter on Cable News outrage cycles that’ll just make you mad with zero impact on anything

I wrote an article on this: https://softwaredoug.com/blog/2020/08/06/political-twitter-o...

Bounce isn't quite the right word. A nation is built slowly and destroyed quickly.

I really wish I could do this. SadlyiI constantly feel like if you don't try to take control, someone will take control of you.

No matter how you live your youth, you will probably regret it when you are older. Unless you inherit so much money that you don't have to ever work in your life.

If you spend your youth having fun and enjoying your youth, then when you get to middle age you'll have wished you worked harder and saved more so you could be wealthy and comfortable.

If you work your butt off in your youth and have lots of money and successful career, you'll wish you spent more time relaxing and having fun in your youth.

The key is finding a good balance between working hard and playing hard. Your career won't suffer if you take a week long vacation. Your health will be fine if you sometimes volunteer to do a weekend shift. Do both and you can be successful and happy about how you spent your youth.

Your career won't suffer if you take a week long vacation.

Move to Europe, and you can take a month long vaction like everyone else.

There's companies in America where you can take a month-long vacation while getting paid a lot more than you would in Europe. Lots of companies with flexible PTO out there in the states, and many of them even allow remote work now.

Inheriting money doesn't change things so much: the people I've met who've inherited a lot of money generally felt a bit lost.

I'm not quite old yet (everyone would say that, right? I'm 35), and I don't regret my younger self at all: during the past 12 years I worked cumulatively 9 years and had 3 years off inbetween jobs. I managed to save up some money, as well as travel and have time for myself.

I sincerely disagree.

Ever since I had kids, being forced to work for a living has been a massive weight on my life. Inherited wealth would be a great help.

Luckily, the fact that I don’t expect to inherit much of anything gets me out of the moral implications of wishing anyone’s death (which is actually the second biggest worry, at the back of my mind).

Ever since I had kids, being forced to work for a living has been a massive weight on my life. Inherited wealth would be a great help.

The problem with these kinds of hypotheticals is that had it been that way, you would not be the you that feels this way.

Aged as I am now, a windfall like an inheritance or a lottery win would probably be invested sensibly towards my retirement. But would a much younger me have blown it all on bitcoin speculation or something equally dumb that seemed like a good idea at the time?

So very true. My girlfriends friend is like this, a woman in her mid 40s and she is so incredibly lost and all over the place.

As an American, this is a very American answer, and I wish I could disagree.

This is exactly what I’m afraid of. I feel I’ll regret my younger self no matter which path I take, even if I take a balanced path.

There will always be choices that I would have made that my future self will deem wrong.

How do I deal with this? Is the key to happiness when older is to just lose all memories?

Why do you dwell on the past so much? Make decisions with conviction and then live with the consequences.

More like you just have to accept that two options are sometimes mutually exclusive. Like which starter pokemon you pick, except you’ll only get to play life once.

That's dark

Being generally mindful of what you eat and how much you weigh should be second nature to you, not something you start doing frantically when you are 50 pounds overweight.

Weigh yourself at least once a week in a consistent fashion (say, in the morning after peeing and pooping). If you notice your weight drifting up (> 1 lb over long-term baseline) for two weeks, do a quick audit of your diet, cut on excess sugar, carbs etc. until it's back to the baseline.

It's relatively trivial to lose 1-2lbs over a few weeks. But doing it once you are 50 lbs overweight will be one of the hardest things you will do, coz you will feel like shit on most days.

Also, if you have not generally been athletic in your youth, beware of doing extreme bulk-cut cycles to gain muscle in your 30s and later. It's easy to gain fat, hard to gain muscle, and you are much more likely to end up just fat while convincing yourself you are 'bulking'.

1. Find good friends; keep good friends. You'll probably only find a handful of these throughout your life. Good friends help validate your existence and make life worth living. They will surprise you. They may turn out to be a lot older than you, or a lot younger. They may be people you grow up with, or only meet online. You may go for years without meeting/talking to them, but as soon as you're together again everything just becomes 'right' again. Good friends: they really are the meaning of life!

2. Anyone who tells you they know what they're doing - they're lying. There's no instruction manual to life. There's no Grand Design or plan or destiny or whatever. Everybody around you is making it up - somehow making life work - as they go through each hour of the day, each day of the year. What works for someone else might work for you. Or it might not. It's your adventure: go live it!

3. In spite of (2) above, learn to listen. Really listen. Open your ears, then open them again. It's how you learn stuff. Taker time to listen to people who you wouldn't normally listen to - like people you take for granted. A lot of the stuff you get to learn will be really useful - often in very unexpected ways. A lot of it will be of no use to you whatsoever, but the act of being listened to may have a profound effect on the person you're listening to. You never know - that person might just turn into your next Good Friend.

4. Growing old - it hurts. A lot. It hurts your confidence; it hurts your self-image. It hurts your bones and muscles in ways you never imagined it could hurt. I think there's a lesson in this, but I haven't managed to learn it yet. I particularly hate my bladder when it wakes me up at Stupid O'Clock because I forgot the lesson about not drinking hot beverages too close to bedtime.

5. Power naps, on the other hand - they're cool!

> I particularly hate my bladder when it wakes me up at Stupid O'Clock

Be grateful, - at least it actually wakes you!

Not sure if it's just age, or other factors but I've certainly seen people who don't always wake up in time.

Your first point also resonated with me and reminded me of this:

"One of the lessons we can learn from history is that people always move on. Sometimes after just a little while, sometimes after years of love and affection. Sometimes unexpectedly, But always.

This is not my advice - I'm 26 - but was given to me at school by a now-retired teacher I greatly respect. It sounds quite wise, and I trust the source.

I paraphrase: "Learn to classify people into three categories: givers, sharers, and takers. Surround yourself with givers. Sharers are also acceptable. Cut out the takers as quickly as you can."

A verbatim follow-on quote: "Takers make a beeline for givers. The needy are always anxious to drain the emotions and finances of those who are givers, before somehow or other they move on to sponge elsewhere, leaving givers to wonder at their own foolishness."

(Edit: apparently people don't want advice from older people to younger people if it's not the older person giving it. I can only apologise. It's the primary piece of concrete actionable life advice I remember that was given to me by anyone more than three times my age.)

This I'm sure resonates with a lot of people, but unfortunately it's sometimes hard to cut out the takers: when they're part of your close friend circle or worse, your family.

It's taken me a long time to craft workable boundaries when you get into the giver - taker situation with someone who is family.

I was having trouble with this once and a wiser friend told me it's perfectly acceptable to say "I've decided x".

So I tried it out, and it seems to work. Some people are much more talented at the right level of response.

Oh, and also: https://xkcd.com/2346/

It's hard not to read "sharers are also acceptable" as either:

1) Be a sharer, but prefer givers as friends

2) Be a taker.

There's always "be a giver to other givers and sharers"!

IDK if at 42 I am considered older, which means that I probably am.

Do take care of your health. Really, do. Even though genetic makeup of our bodies obviously plays a role, at my age the gap between people who care and people who don't starts resembling a chasm. You have slender and vital fortysomethings that still hike in the mountains and you have 400lb T2 diabetes sufferers who have hard time tying their shoelaces. Don't strive to be the second type. Imprisoning yourself in sick body is not cool.

Some substances like tobacco, alcohol and sugar are emphatically bad for you, especially in quantities that we tend to consume. Our modern society is all about overconsumption, so buyer, beware. Having a piece of cake every few weeks is OK, but you will be driven into making it a daily habit, unless you resist the pressure. Resist it.

There is one more reason to keep yourself healthy. There are absolutely fantastic treatments in the research pipeline. Stem cell regeneration, genetic modifications etc. Some of those will fizzle out in the testing phase, but some will not, and those that prove themselves will change what "aging" even means. In 2050, heart attacks, atherosclerosis and cancers may be as rare as scurvy is today. Today's middle aged and young people will probably have much better silver years than anyone before.

But you really need to survive the next decade(s) to make use of those developments.

I not sure why you mention 40 somethings being still able to walk in the mountains. That seems pretty normal for my peer group, but I agree that might not be the case for others. My dad was able to do fairly strenuous days in the mountains easily in his 70s and goes hillwalking and fishing in his early 80s still. I don't really have a handle on how normal this is as most of my friends are kind of similar (UK based, but I know quite a lot of people overseas too)

From my former university and high school colleagues, about a third are already too obese. 50lb+ over healthy weight.

Another third is not yet as far gone, but still lead very sedentary lives, home to car to office to car to home.

Only the last third are people who could summit a 5000ft mountain without totally finishing themselves off.

That's pretty sad. Last year I was trying to get in a bit better shape. I was regularly doing over 100 push ups in an evening, some kettle bell workouts, kayaking at least once a week and cycling once or twice a week up to 100 miles in a ride.

I was easily one of the less fit members of my peer group. Almost everyone I know goes running often, some doing ultras (I can't run due to knee problems). One of the least fit of my uni friends now does at least one full ironman(woman) a year.

I find there is a real fitness culture around me, probably due to fear of aging. Along with diet/meditation it's the only positive way to safeguard your future aside from reproducing.

From people I know in Europe or North America I'm also getting the same vibe. I wonder what's so different with the people you're aware of? I'm guessing either too much work or it just doesn't seem like a priority or even worse, they think it's too late!

I thought about your last comment yesterday, when I was sitting at a table with a dozen other people in the 35-55 age bracket. I did a short count.

Four of us were normal weight, including one very fit guy who is sorta Czech Indiana Jones (archeologist working around the world, very cool job). Four were overweight, but still somewhat active (e.g. at least going around on a bicycle). Five were seriously obese, with massive bellies.

So yeah, the principle of thirds seemed to apply. TBH this has grown worse in the last 30 years. Around 1990, even here in Czechia where a lot of beer is consumed, average adult person was fitter.

My advice at mid-50s to younger people is to learn 1. manage your energy for your long term health, 2. enjoy time with the highest quality people you can find (I mean that in terms of good language, hopeful, constructive/collaborative in nature and working on themselves, empathetic to all those around you), and lastly say "yes" to almost everything and enjoy to the max. If my life were a candle, every year it is slowly losing some if its brightness/energy through no fault or effort on my own. I had an unusual situation which aged me faster than I ever wished for-- lost my mid-30s wife to a rare cancer 3 years after diagnosis. A part of me died with her and my heart will never heal. Still I wake up hopeful every day. We are all along for a short ride, enjoy the hell out of it. It could/will disappear in an instant.

This is heart breaking man.. this freaks me out. I’m a young parent, two small kids. Working and trying to keep the family going has been hard on us and our relationship. Need to tell my wife I love her more, you’re right it can go at any second. This is a good thread..

I'm 56, so not that old, but age is increasingly a concern. Confirming what others have said - I am very much in touch with the teenage me and everything between. The days are long and the decades are short, indeed.

Health - for me, health it isn't about living a long time, it is living with self sufficiency and minimizing pain. I am not afraid of death, but I am afraid of the years of infirmity which often precedes it. I'm afraid of living the end of my life without my wife, but even more afraid of leaving her to finish life alone.

Regrets - I wasted too many years missing opportunities for fear of disappointing my parents or (later) risking appearing foolish. I assume HN has a higher than normal mix of introverts, so maybe you can relate.

Urgency - turning 30, 40, even 50 didn't phase me; I felt young and time seemed endless. But in the past five years the switch has flipped. In 14 years I'll be 70. The mortality curve is tilting up dramatically; friends and family will have died (perhaps me too). Many of the things that I always wanted to do will not be possible, so I had better attend to them now. There are far too many such desires, so triaging what is most important takes up more of time.

Work/life - I'll do my job competently and I'll leave it to the younger folks to be the hero at work. I think back on the deadline death marches and jumping on grenades to get projects back on schedule ... and every one of those deadlines was a sham. The products I sacrificed so much for were in the discount bin a year later.

“ I think back on the deadline death marches and jumping on grenades to get projects back on schedule ... and every one of those deadlines was a sham”

- I’m only just beginning to recognise this. I checked myself out from hospital early this year to join a standup meeting, to make sure the project was on schedule. Thinking about that now makes me angry. It was pointless.

> every one of those deadlines was a sham. The products I sacrificed so much for were in the discount bin a year later. <

Same experience here. I can't blame the companies though.

I was essentially a workaholic for decades. I wanted to believe I had a noble mission to fulfill, aka "true believer" or "clueless" àla Gervais Principle. It took me a long time to realize this attitude was incredibly damaging and wasteful. It's tantamount to smoking or other major self-destructive behavior.

I'm in my thirties right now and I feel a huge sense of urgency already. I hate that life is so short :(

What length of life would you find satisfactory?

I would like to live about a thousand years, but I'd be happy for a few hundred as well.

A never ending one, certainly.

Say no to fun stuff 20% of the time and invest that money - the younger the better. Time is your very best friend when it comes to retiring comfortably. But say "yes" to enough things that you'll have fond memories to look back on with friends and family.

Time does start passing quicker. Perhaps the brain slows down and you capture fewer frames per second, but the end result is you start to learn how important it is to prioritize to avoid having spent your precious time on trivial things instead of meaningful things.

Time is infinitely valuable compared to money. Do the math. You can always earn more money, but you will run out of time. Does that contradict my first statement? No. When you're older you'll want enough money to be able to spend your time as you wish.

The vast majority of things you think are of the utmost priority now will seem trivial looking back on them ten years later. If you can learn this early it makes it far easier to remain rational about your decisions and how much things are worth.

Your body will start getting in the way of things you want to accomplish. You'll get tired sooner, you'll have health problems that interrupt your momentum or require long periods of recovery, it will be frustrating to struggle at things that were once easy. Don't wait too late to do the things you are truly passionate about. Retirement might be too late.

I'm only 47, but I have a couple guiding principles that have been helpful so far. The first is to stay flexible. I've been a runner, hiker, bicyclist, climber, kayaker etc all my life. I've gone in and out of shape depending on what's happening in my life. The only times I've really struggled physically have been when I let my muscles get really tight. Three weeks of steady stretching has done more than anything to make me feel better physically. If I can't run for some reason, maintaining flexibility makes it much easier to pick up any of these activities again.

The second is to find some new, significant challenge in each decade of life. Learning new things keeps us humble and alive. In my twenties I focused on teaching and long-distance bicycle travel. In my thirties I moved to Alaska and began doing mountain rescue work. In my forties I wrote a book, changed careers, and learned to drive a boat on the ocean. Each of these new experiences made me feel like I was 20 again, taking me far outside my comfort zone. In future decades I hope to learn a musical instrument well, and travel internationally. I'd also like to take another long bicycle trip and live without a motor for an extended period again.

There is great joy in growing old; it's much better than the alternative. :)

I'm surprised that most of these answers are individualistic. I'm 48, so not really the target respondent, but I've got this to say: getting old is not about me, it's about what I have to give to my wife, my children, my colleagues, my church, and my community. I have faith I'll get what I need back from them, when I need it. For now, I'm investing in my future by investing in those around me.

This seems like it isn't physically related, but it is: as the years accumulate, it becomes more and more clear that the person staring back at you in the mirror is the one you have to live with most intimately. Do the best you can with what you have, in all things, always. The person in the mirror will know whether it was the best you could, and he or she or they will also know whether you can be forgiven for any given action given what you had at the time. The biggest part of this is unkindness: If you are unkind, that person in the mirror will never let you forget it. You may not spend much time on this when you are young but you will spend a lot of time on it when you are older.

61. Choose your life partner with care.

Three in the morning and a kid with 105 who has been throwing up for a day and you have to decide what to do. A crappy apartment but making a morgage would be a real stretch, no fun for years, and you need to work it out. A job you want but in a place far away from family and friends. These things and many more will be between you and them.

Finding somebody you like, and admire, and who you like to get sexy with, and who has something of the same idea about money as you do, and who wants many of the same things in life, is tough.

My first advice would be to not underestimate the importance of sleep. This is a key factor for both quality of life and productivity. The only way to optimize sleep is to sleep enough.

Second, try to understand the power of compound interests as soon as you can. Life is long enough to invest and see the returns. Invest in yourself and in projects with long-term value, don't be seduced by shortcuts and don't be a slave.

Last thing, there is a lot of blind and seemingly unjust randomness in life, it is better to embrace it.

I've "slept enough" for a couple of years and developed a severe case of insomnia. I couldn't fall asleep till 2-3am, then slept till 10am to make up for it. Repeat. Bad idea.

Waking up at a regular time and restricting my sleep below what's comfortable has helped very quickly. I'm considering sleeping more, but feeling slightly groggy after sleeping 6.5 hours is way better than spending 10 hours in bed, 3 of them suffering.

Good point wrt unjust randomness, I'm terrible at embracing it. Any tips?

My tip would be to discriminate between what is under your control and what is not.

Typical things that are hard to control: the law of physics, the weather, 99.99% of human beings.

Not reading the news might help.

Insomnia is a sign of a deteriorating mental health, you should focus on that instead of trying to hide it.

Do you have any references for that? Can't insomnia be caused by various things?

In my case I'm pretty sure it was the consequence of sleeping comfortably long in the morning and waking up at irregular times.

"Insomnia" can even be a sign of healthiness. It is often to see people experiencing a smaller need sleep while on ketosis/low-carb diet. I've been sleeping 5-6 hours every day for the past 2 years and although it bothers me (because I liked to sleep a lot and still enjoy it), I don't feel tired all day. Usually I also take a 30minutes nap around 1pm.

>Randomness

When life gives you lemons, make lemonade

Ageism in tech is real. Don't act like you won't be old one day when you scoff at an older engineer's resume during the interview process.

You will blink your eyes and be on the other side of the interview table in due time and be thinking the same thing my friend.

How to protect against both outcomes? Should I start learning the fancy front end framework of the week, or aggressively increase comp to FIRE?

First of all, save as much as possible. If you are young, single and making SV market rates for engineers, there is no excuse to be saving less than half your take-home.

Second, learn the business and big picture of what you are doing. A lot of engineers are inclined to go deeper and deeper technically, and indeed there is a path to riches here if you are exceptionally good and also have a bit of luck with your choice and circumstance of specialization. That said if you are lucky enough to navigate this, you will have the golden hand-cuffs as only very few companies can properly compensate and utilize such experts. Far more reliable is general purpose business knowledge, specific domain knowledge, and/or collaboration skills. Combining these things with programming skills is a super power that will give you a lot of flexibility later in life.

Stay in great shape and health. No youngling is ageist against a fit grandpa, because most of them can't get fit in their age, much less when they get older.

When I was younger, I could skip most of the homework because I learned enough during class. The mandatory assignments were sometimes finished quickly just before I had to turn them in.

I didn't get the necessary practice and discipline to do independent work unless I did it for fun. This had to be learned the hard way when I grew older.

Same. In my experience, the relatively smart people in school who worked hard had more successful lives than the even smarter kids who didn't.

How do you define success?

In the context of my comment, better jobs. Doctors, lawyers, and proper engineers and such. Basically, the kids who worked harder excelled in college and stuck with it.

I had a similar experience.

Please don't praise kids for being "smart", teach them that putting real effort into something will pay off.

You need to do both. Don't be that stereotypical Asian parent, pushing and never praising.

It works only sometimes, and the kids will curse you for their empty, wasted in third, life.

Just because you don't praise kids for being "smart" doesn't mean you can't praise them for their actual accomplishments.

1, people don't feel old mentally, they feel like a young person trapped in an old persons body

2, time goes by way faster than you think, blink and you'll quite literally miss decades of your life

advice? don't ever put off until tomorrow what you can do today, the old you is depending on the you now to look out for him/her.

"Bomanz let his thoughts drift. The truth was elusive. Stance would not remember the good years. “I guess because people change and we don’t want them to.” He could find no better words. “You start out with a woman; she’s magical and mysterious and marvelous, the way they always sing it. Then you get to know each other. The excitement goes away. It gets comfortable. Then even that fades. She starts to sag and turn grey and get lined and you feel cheated. You remember the fey, shy one you met and talked with till her father threatened to plant a boot in your ass. You resent this stranger. So you take a poke. I guess it’s the same for your mother.

Inside, I’m still twenty, Stance. Only if I pass a mirror, or if my body won’t do what I want, do I realize that I’m an old man. I don’t see the potbelly and the varicose veins and the grey hair where I’ve got any left. She has to live with it.”

“Every time I see a mirror I’m amazed. I end up wondering who’s taken over the outside of me. A disgusting old goat, from the look of him. The kind I used to snicker at when I was twenty. He scares me, Stance. He looks like a dying man. I’m trapped inside him, and I’m not ready to go.”

> the old you is depending on the you now to look out for him/her.

This is powerful. Thank you.

Be cognizant of phony social pretexts. I can remember everybody saying I needed to go to college. I did but I don’t college to be a software developer. Go to college not because of some bullshit social pretext but because you honestly want an expanded education.

Do the hard things first. Hard things get easier with practice but practice takes time. The easy things remain easy regardless of practice and just rob you of the time required by the hard things.

survivorship bias

Good point. But really, all advice from older persons to younger persons carries a strong element of survivorship bias. The data are biased but RCT studies are not practical so it's reasonable to use what we have (recognizing the limitations of our data, as you pointed out).

I don’t believe survivorship bias applies... yet. Even though I do have a bachelors degree (not computer science) I barely graduated high school. Even still I am doing well as a senior developer having surpassed many of my peers. Yet many of the strongest developers I have worked with personally are also self taught. I believe that once I take my peers into consideration there is a frequent reproducible pattern.

It becomes survivorship bias when I become more specific and speak to what works versus what does not, particularly in contrast to common faulty social expectations.

I am 47. This Buddhist quote captures the rapidity of life - "Days are long; Decades are short".

Be kind. Really try to be kind. As young person, I am sure you already can recollect a few instances you have been kind; increase the frequency and amplitude of it.

This post is so much full of wisdom.

Your body just won't work like it used to, even if you do all the right things to keep it up. When I was in my 20s I could spend all day working the yard, cutting, raking, digging, sweeping. I would stretch afterwards and be find the next day. Now, despite having an even greater level of day-to-day physical activity and more exercise, it will take me a few days to recover.

Once you hit 40 you start feeling random pains in places. Sometimes pretty intense pain. Your doctor will have no idea what caused it and tell you it's normal, but let them know if it happens again. And after a while you'll just stop telling them, because it's just a thing that happens now.

I’m 45. At 40 I wondered if I’d ever feel successful. I’d just been fired from a shit job that took advantage of me and once again I was trying to scramble to find meaningful employment. I found it a month later, and now retirement at 50 seems like a remote possibility if save aggressively and live a modest life.

Feeling hopeless at 40 sucked more than feeling hopeless at 20. Feeling hopeful at 45 is more amazing than feeling hopeful at 25. So I guess I appreciate the good and the bad more now than I used to.

Losing weight or gaining muscle mass gets harder and harder as you age so the older you get so its important to keep a diet and exercise routine that keeps you at a good condition cause letting go makes things go bad much quicker and takes way more effort to get back in shape.

On the other hand, you should accept that you'll go frail, so it's better to not tie your career to being fit if you can help it.

Unless you earn tons of money and can retire by 40, all debts paid.

If you stay fit after 40, ageism is not going to be a problem for you, as you will always be seen as a senior/reference for the younger.

I'm not 'old', but I'm not young anymore either, though I still remember it. My biggest personal gripe is my brain slowly slipping. It's just not as fast as it used to be, and my memory not anywhere as good. I was always a person who could remember everything, even playback full conversations in my head. Now I barely remember what I had for dinner a couple days back.

This has affected my work as I used to just be able to sit and code for hours in Vim as I'd have all the function signatures memorized, but now I spend a lot more time in the docs and have to use a proper IDE. I now write more helpful comments, so I can remember why I did something. Also, I find myself having to take notes to come back to later. I wish it was a skill I'd picked up when I was younger, rather than having to learn now.

> Also, I find myself having to take notes to come back to later.

I rely on notes too. I'm not sure it's entirely due to my memory getting worse with age. It's also that as you progress to more senior or leadership roles over the course of your career, the rate at which you become interrupted by questions or meetings increases, and the number of different issues you need to juggle also increases. I use my notes as a non-volatile memory to save my current mental state so I can resume after these interrupts.

If I'm coding uninterrupted and in a state of "flow", I can still remember details of my code from years ago.

Cartoon about interrupting a programmer: https://heeris.id.au/2013/this-is-why-you-shouldnt-interrupt...

I’m experiencing the same thing with regard to memory. I’m not sure the cause. While I used to be able to recite full conversations, tell you the color of the trim of that car I was in one time nine months ago, and tell you the shape of the dust lying on the convenience store counter, etc. I can’t do that anymore. But I also think a lot more about a lot of other things that either didn’t concern me when I was younger or weren’t my responsibility.

Maybe now I can’t remember things because I’m not experiencing them as thoroughly because I’m always thinking about something else. Or maybe I just realize a lot of details don’t matter. Or maybe it’s just age and my brain doesn’t work as well. Or maybe it’s accumulated damage of twenty years of occasional consumption of alcohol.

Yeah, you might be right...maybe we just store so much we start evicting the LRUs so to speak.

One other phenomena I've noticed is that I've begun misspelling words a lot. Not like poor spelling, but using their/there/theyre incorrectly, homophones like fill/feel, or plural is vs plural are, etc. I know these things, it's like my brain goes into autopilot. Probably payback for always correcting people when I was a smartass of a younger person.

Ride a bicycle and learn C (I've been doing the first for 50+ years and the second for 30+ [0]).

Some skills never go out of fashion.

[0] Personally, I found learning C harder than falling off bicycles.

> Ride a bicycle

With or without the helmet? Because the opinions are divided.

If you wouldn't ride a bike because a helmet was mandatory, then without.

I am very surprised my C (C++) skills seem to be in demand still - even seems to be a bit of a renaissance at the moment.

Once C survives 100 years, it will likely survive 1000

Yup. https://en.wikipedia.org/wiki/Lindy_effect

Why are you surprised? I have to write firmware all the time and everyone still uses C unless they're dedicated to another language for some reason. I can see being into Rust. I haven't had any reason to use it yet.

Memory safety? Isn't that a reason to use Rust over C, that there are some classes of errors one can move from runtime to compile-time?

I'm not saying there's no reasons to use Rust over C, but I am saying that I'm not surprised C is still highly valued. I was still being forced to use assembly for firmware a decade after I learned C.

I will not be at all surprised if firmware stays in C until Rust has been practical for use in firmware for several years as well. I don't doubt it'll happen, I haven't written a line of assembly for my firmware in a decade either, but consider how many hundreds of thousands of lines of C there are in the libraries for just one target architecture.

It sounds cool and useful and I'm looking forward to it, but every time I start asking around if Rust is worth the effort the answer from people who use Rust a lot is "not really" because my projects aren't big complex firmware beasts. I am not surprised that a firmware developer with expertise in C can easily find work.

This reminds me of the time I interviewed for a developer job at a young startup (college dropouts and just-grads), and the interviewer asked me, age 26, "what is like to be so old?"

Given time, you'll see.

I distinctly remember, at age 19, not being able to imagine what it would be like to be old — like, 25.

My elementary school teachers were real old women. Like 20.

If you often don't feel well, keep investigating. Don't just let it go if you see a couple of docs and they can't help.

Certain disorders are so subtle and poorly understood that they may go undiagnosed for years -- and those years may later be recalled as having held very little fun for you. Examples: autoimmune, food intolerance.

Take care of your body.

People matter. Learn how to interact well with them. Yes, it matters that you be yourself, and that you hold to what is true, but don't use either of those as an excuse to be clumsy (or worse, brutal) with people.

Even things like clothes matter, because they're part of how we interact with people.

Don't wait until you past 40 years old to take care of your health. Starts now.

Physical exercise becomes more important to fight against aging. Especially core exercises to take care of your back.

Watch your diet and eat well because it's so much harder to lose weight when you are older. Not to mention your innards are deteriorating fast if you abuse them.

Contact sports or extreme sports has super high cost when you are older. Imagine breaking your wrist playing snowboard and you have to be out of work for multiple months, unable to make a living by typing, etc.

I'm 39 and still recovering from a wrist injury from trying to learn snowboarding last year. One's body does not heal quickly after a certain age -- and beyond some point, I imagine it never really recovers from certain kinds of physical damage.

When I was 38 I completely broke my left radius bone into multiple pieces at the wrist end while snowboarding at Squaw Valley. On the x-rays it looked like it was crushed into tiny pieces at the wrist. The doctor said I was lucky it had been reset so well, and that I probably would not get full range of motion again, but I was young so maybe I would. I said I was almost 40; he said yeah that's young.

I could still type, mostly, and was back at work (at EA) within a few days. The cast came off at 6 weeks, but it took years before I could do pushups without pain. I finally got the full range of motion back after several years.

Hope your injury heals fully.

My experience with aging is that you accumulate more and more injuries and illnesses and heal more and more slowly.

The advice I'd give is to assume that any activity you might ever want to do will be harder next year.

I've posted about this many times here and so have a lot of other people: If you're suffering from any chronic aches or pains especially back pain or RSI it may be TMS (though only a doctor can tell you that but you need to be informed).

The internet and medical community is full of misinformed people who will fill your head about how a pinched nerve or a slipped disc can cause you immense pain and some doctor may even put you under the knife. But at least read about TMS before you do something drastic.

See tmswiki.org (not my site) for hundreds and thousands of people who have recovered from decades of back pain after spending hundreds and thousands of dollars but never realized it could be simple TMS which doesn't cost a dime to fix.

I'm amongst one of these people and after nearly suffering for many many years did someone on hacker news posted about it and that comment changed my life literally. Pain is all I could think about back then and it interfered with my work, relationships, life. Just reading Sarnos book got me halfway there. Then daily exercises and watching hundreds of testimonials on YouTube made by common people helped me more.

I can only attest to back surgery being very, very risky and yet pushed as the obvious answer to severe back pain. An acquaintance of mine had failed surgery for a pinched nerve and his life went downhill fast.

What does TMS stand for?

According to the website in their comment it apparently stands for "Tension Myositis Syndrome (TMS)" (https://www.tmswiki.org/ppd/An_Introduction_to_Tension_Myosi...)

It stands for tension myositis syndrome. This is a good introduction to it (1)

(1) https://www.tmswiki.org/ppd/An_Introduction_to_Tension_Myosi...

as others have said, tension myositis syndrome. The theory is supressing uncomfortable thoughts results in the body instead trying to communicate them as pain.

I personally think its quack science, but it seems to work for some people, so that is what matters.

I had persistent idiopathic back pain in my 20's. The cure was abdominal strengthening exercises, and better attention to posture.

Experience the benefits of fasting -- it will take care of excess weight and has other benefits.

Second this. Been doing a variety (16:8, 18:6, OMAD, 36/48/72hr) of fasts for nearly five years now and it has been a life changer.

For those interested, check out The Complete Guide to Intermittent Fasting by the Canadian nephrologist (Jason?) Fung.

Also see Thomas Delauer's yt channel. Many good tips there. I do 1x 36 hr/week for abt 1.5 years now.

What type of fasting do you do?

2x 36-hour fasts per week. Its not hard or impressive but still has a big effect.

I had my 25th wedding anniversary this week. My advice is to go for the boy/girl you think is too good for you. Whether that be brains, personality or looks. The young often lack confidence despite their cockyness. I got lucky and got the girl who was out of my league. My self doubt nearly sent me down a different path.

It's never too late to get healthy at any age. I've realized this after many years but have finally started to take it seriously.

I follow a lot of literature and social media around fitness. I think the rise of social media has made fitness seem out of reach for most people. Seeing these fitness personalities usually being in the top percentile in terms of genetics for body weight, muscle definition and just looking amazing makes the rest of us feel like it's not something we can do easily. Having most of these people spout their pseudo science also doesn't help. It's hard for any sane person to understand what to do, whether its diet (keto, low-carb, water fasting, carnivore diet, etc.) since there is so many possibilities.

As I've grown older I've realized that staying fit has so many benefits that it might as well be the best anti-aging change we can make for ourselves.

If you're over 25% or more body fat, it's worth figuring out how to bring that down to 20% or less. See how far you can go. Not all of us can get to 12% and maintain it without feeling like we're starving ourselves but I think the higher range is doable.

I've realized for diet and exercise there is no one answer for anyone. The wisdom of eat less, exercise more seems to be the ultimate truth.

What that looks like for each person is unique. Personally for me I've tried all of it. I've done the 7 day water fast, intermittent fasting, low-carb eating, etc. At the end, as long as I'm eating within my maintenance calories relatively good clean food it doesn't matter for me which one I do.

For exercise, I've settled on three total body weightlifting sessions with half an hour cardio session on the non-weightlifting days.

So, the best thing you can do as you getting older is figure out what works for you. There is so many ways of eating and exercising and sometimes it takes a while to understand what works for your body.

Preach, brother.

I was never really obese, but I was overweight. It is worth knowing your actual body composition, not just total weight.

At 36 years of age, I had 24 per cent body fat. Nowadays, at 42, I have 17 per cent body fat. My weight is actually almost the same (+- 5 lbs).

But health and overall wellbeing is very different. Getting rid of high blood pressure and knee pain is a huge improvement.

Don't worry - it will all work out. I spent a lot of time when I was younger worrying about stuff - stuff that never happened. The stuff that did happen I never thought about until it happened. I don't worry any more - everyone I know who's having a good second half doesn't worry. (I don't mean skip the basics - save some money, look after your health, don't drink to much)

My father is 64. He has just been given months to live. He will be the second in my family to die from lung disease caused by smoking. My advice for any young person, don't smoke it'll rob you of years of life.

I saw some folks years later from my home town and some of them looked older, and they seemed to be smokers.

(My sample size is kind of small, and for all I know they had a different lifestyle or were out in the sun more)

1. Language is just a tool our species uses to act through others, invented as a necessary means to protect and manage children and that has evolved to other uses, but it is a narrow keyhole through which to experience the world, or to express it. Most suffering is an artifact of it, and most joy is inexpressible in it.

2. Regret is almost always about what you didn't do, and rarely about what you chose freely or decided yourself.

3. Understand the effect of compounding in every endeavour.

4. There is no 4.

There is 4 for everyone, called Death. Make sure you'll enjoy it, both the transformative metaphorical one and the literal one.

If you're lucky, you'll stare into it sooner than later and become better for it. (When you're old, it's hard to do anything about it.)

Once you get it, you will know how to live your life to fullest while not leaving a debt and cleanup to others.

As a man gets older, he seems more harmless, even neutered. At 66, I can now have much more substantive conversations with (for example) young women.

Advice: some lessons come only with age. People often don't learn not to care what other people think (because they're not thinking of them at all) until their 30's. It was only recently that I really learned that if you don't have expectations, you can't be disappointed.

I realized at some point that if I took a 1-year break between high school and college, I could've secured retirement right away.

$12/hr is $24k/year. The summer after high school and the full year that follows is 1.25 years. That's now $30k. Working nights and weekends (2 part-time jobs) doubles it to $60k. After taxes, there's roughly $48k left. $40k would roughly double (in the original year's currency) every 10 years if the S&P 500 kept growing at the historical average 7% over inflation. That's $640k at 59 and $1.28MM at 69.

Meet all RDAs with just a variety of quality whole foods, 1:1:1 calcium:phosphorus:magnesium, and ensure sufficient quality sleep. Sustained-release melatonin eventually. ZMA may work well enough for younger males.

Keep big hormones at pubertal levels as long as you can. Naturally (just foods, vitamins, and minerals; not excess protein or other tricks) raise IGF-1 as much as you can. Match levels of progesterone/melatonin, hGH, and DHEA present at the age IGF-1 represents.

At most 5-10% of romantic pairings can be minimally mutually satisfying once the dust settles. Not 5-10% of relationships entered by a person. Rather, 5-10 out of 100 randomly selected males and 5-10 out of 100 randomly selected women. Such a reality does not mute love, lust, the initial high/spark that can last months up to even 2.5 years, or pregnancy.

Many can go a long time without realizing compatibility once paired is uncommon. Worse, as 20% or 50% of women encountered (by MSW) are a mutual match. Overlap (many matching with the same 20%), aesthetic misalignments, etc all reduce likelihood of progression.

The typical ages at which men and women get married are 29 and 28. 50% between those 26-35 end in divorce within 10 years. 2/3rds of second marriages end within 10 years. 75% of third.

80% of people over 40 have been married at least once. 80% of women over 40 have had at least 1 child.

25-30 are peak years for saving. And f*cking. Avoid (relationships,) marriage and definitely kids until after. Wait until you can think clearly.

Why buy a house if you don't have any kids? Houses are easily a trap. Always pay cash (ie, avoid debt). Even for a car. Even for an education (tricky). And even for a house!

Save at least 50% of take-home salary to a high-yield investment account, even if just buying up the S&P 500 fund. Eventually, the amount saved/compounded will recover all after-tax money ever earned. At such a time, the interest/DRIP income will replace the take-home salary. Usually happens in 15-20 years.

I think growing old in 1900 is diff from growing old in 2020. I don’t think these are experiences that translate well over time and place.

‘What advice would I give my younger self’ also doesn’t compute. Because that would mean that I would end up with entirely different life experience and the person giving the advice would not exist as they would have changed. In sci fi, this would be the classic causal loop/temporal paradox time travel dilemma.

If this is about health, you are better off obtaining a DNA report and go through the high risk illnesses you have inherited with your physician. I did this and was able to identify a few things missed by my previous maternal units. Some of them probably died because one mutation was undiagnosed.

From a dietary perspective, follow the grandmother diet. Eat what your longest living ancestors lived. It helps if you haven’t migrated far off.

P.S: Don’t rely on dna ancestry reports migrations. I am South East Asian and ancestry report suggested that I had a Finnish ancestor. I doubt if I can follow the Sami diet. In California. So there is that...

My suggestion is to draw a family tree for upto 4-7 generations. 7 is ideal but would be tough for most.

Are you actually worried that speculating about your younger self might accidentally erase you from the sands of time? We don't actually have a way of delivering our advice to our past selves, so the activity seems mostly harmless.

When asking this question, I assume the many worlds theory and giving advice to my past self would simply break off into a new branch. I’d still exist the same but his life might be different.

i am reminded again for the second time this week of Robert Heinlein's By His Bootstraps. This and All you Zombies tackle time travel paradoxes in a satisfactory way.

https://en.wikipedia.org/wiki/By_His_Bootstraps

+ PKD's The Skull...: https://en.wikipedia.org/wiki/The_Skull_(short_story)

actually, if time travel exists..you wouldn't be aware of it. especially if one of your descendants visited you.

Does anyone know how to learn more about one's DNA for the purpose OP suggested, in a way that respects privacy?

“In a way that respects privacy” is very difficult. There are companies (Dante Labs for instance), which will do comprehensive genetic testing (full genome sequencing), but privacy is complex. Once the data exists, it’s very hard to un-exist it.

I would highly recommend avoiding Dante Labs. I had a terrible experience with them. There were extreme delays, lasting many months. When I requested the full genome be sent to me, they insisted the only way to do it was a hard drive. This hard drive was sent from Italy to California. On its way, it was seized by customs in Mumbai, who opened it and re-sealed it. The package arrived in tatters, and based on my analysis of the genome with the appropriate reference, it appeared to be someone else's genome. Many of the SNPs disagreed with a later 23andme report I got, which I assume is more accurate.

It is called a thought experiment[0]. It's useful because it doesn't have to create such a time paradox because the thing only happens in your head. It's pretty powerful to help people think outside the box.

Yep, people completely get confused about "cohort" vs "age".

"Cohort" is the year you are born. This might make you a Baby Boomer, X, Y, Z, ... You keep your cohort throughout your life.

The cohort who got physics PhD's prior to 1968 got jobs in the field easily (e.g. most were good at physics, it didn't matter how good you were at musical chairs); after 1968 the job situation changed (you certainly were good at music chairs.) This is a function of when you were born.

Life's short. Don't spend it in debt to banks. Paying off your debts is life changing. Imagine heading into the 2008 recession with a paid off house and car, and an emergency fund that will pay at least 6 months of expenses. Financial worries are one of the top 3 things couples argue about. Be different.

Don't sabotage yourself by not taking care of your body. Avoid alcohol, tobacco, and other drugs. You can live without them, and you'll be much healthier. Avoid excess sugar. If its not a desert, it should not be high in sugar. Work out. Take walks. Hike. By the time you're 50, you'll notice that people who have not taken care of themselves are no longer able to work mentally demanding jobs.

Pay attention to stress. It's the big killer. It will kill your ability to think, and your ability to have meaningful relationships. And, eventually, it will kill you. If you're getting stressed, find a different way, a different job - change whatever you have to.

The things you spend time doing will become the things you do: What you're good at doing, what you have a habit of doing.

So be intentional to spend time doing things you actually want to focus on, or become good at, or have as habits.

I suspect this advice, like most advice from the old to the young, is difficult to really understand or follow from the perspective of the young.

How old is "old"? FWIW as i got "older":

Health:

when young I suffered muscle pain when I worked out. At 40 the pain changed to a skeletal pain, which wasn't nice. At 60 it started to be more tendonitis than anything else. At 70 it's gone unless I suffer an injury, whereupon weird stuff happens, e.g. hand injured a little in a fall, subsequent cat scratches cause the injury to flare up, time to get an antibiotic injection - strange!

I feel heavy, especially when I lay down to sleep at night. OTOH I'm working out more consistently than I ever have, my weight is down from 220 to 185, and so probably I'm more dense.

I'm much quicker than I ever was: I catch falling objects mid-air, stop other's falls, intercept slips and, in general, am scary quick. This weirds me out a bit. I have heard that some people are quicker than others but, other than extremely obvious cases of physically slow people, didn't believe that it was possible for one person to be significantly quicker than another. I've changed my mind about that now.

I have no known serious problems - everything is working fine, and am primarily concerned about my CV system: all else will IMO follow. I take a low dosage statin but I may not need it. More importantly, I'm realizing the simple frailty of the human body and so have re-evaluated different activities: driving (still do), cycling(won't do - crazy in my city!). Back pain: had it since I lifted too much weight 40 years ago. Almost debilitating in the last 2 years until I found some simple exercises that made it go away. Most every man will suffer at least one serious back injury - if you do, you just have to keep searching until you find the fix that works for you.

Advice:

1. Don't ever ever pick up more weight than you've picked up before unless it is a real emergency, 2. If a sexual opportunity seems too good to be true, it probably is - don't accept it. Herpes(or worse) is no fun, no matter how the herpetic community may spin it. Note to my younger self: don't touch the beautiful blonde!

3. Always take the highest offer but be ready to walk out if things go badly.

4. Don't fall for the sunken-cost fallacy - if you're in a bad relationship of any sort then get out early and consider yourself lucky. See "The Art of Thinking Clearly by Rolf Dobelli for more. This especially includes love.

> I'm much quicker than I ever was: I catch falling objects mid-air, stop other's falls, intercept slips and, in general, am scary quick.

I'm much younger, and definitely not "scary quick", but I did get significantly better all of a sudden after starting to mind my omega-3 intake. Could this be related for you as well?

I've learned that "old" is just a sliding scale. When I was in my teens, I considered 30 old. When I was in my 20s, I considered 40 old. And so on. Don't get too hung up on the exact number.

Also, there's a physical age and a mental age. One definition of old is, when these numbers don't match up anymore. And yes, by this definition some young people are old and vice versa - that's the idea!

Saying, "I'll do that when I'm older or when I retire" just means that you'll never do it.

Getting older usually means acquiring more experiences. It doesn't mean that everyone is equally good at it, typically a healthy dose of self-reflection helps.

And lastly, memories tend to fade, which is a blessing, pr sometimes a curse. But mostly it helps to blur things in the past. Which explains why older people tend to idealise how things used to be (they only remember the good parts). But it also helps people get over things.

If I can be so bold to offer up some of what I have learned in my short existence (am in my mid thirties), none of which is my own wisdom but simply cemented in place by my own experiences.

After going through a tough time with a parent in my early twenties, where an accident involving brain hemorrhaging caused a massive shift in personality and speech, I can not stress enough how good advice it is to savour and fully utilize each moment with your loved ones while you can. He ended up passing away less then a year after the accident.

Get rid of your fomo. There will always be new tech. There will always be something new. You can't do, see, experience, read, learn it all. Having gone through my twenties often in crippling fear of being "left behind", I look back now and see that I enjoyed those years less because of this need to be up on everything, which just had the oppposite intended effect.

Your health is important no matter your age, your mental health doubly so. Strive to work smart, not hard. Realize when you are being pushed into a situation where your health is going to be impacted, and stand your ground against it. I have gone through three burnouts, each one more serious than the previous one. One caused a relationship to end. Last one required me to seek professional assistance (which by the way helped immensely and I now openly talk to people about without shame). Know your limits, and work on pushing them in a reasonable manner, but do so on your terms if that is what you want to do.

Realize how difficult it is to live with another human being for a long time, and how rare it is to find somebody who genuinenly loves you for who you are as a person (both the good and the bad) and will stand by your side through thick and thin (and your own bullshit). Treasure that kind of relationship, above anything else. Momentary opportunities come and go. Never jepordize what you have for short time gains.

And be financially smart and frugal. Save. But also live life.

I actively avoid trying to let nostalgia creep in too often. I don’t spend much time reminiscing, listening to old music, rewatching things, looking at pictures, etc. This seems to not match what most of my cohort does, but I recognized a correlation between too much looking back and feeling somber.

Trust no one, just because you work well with someone doesn’t mean they like you.

I'd like to suggest a more optimisic alternatve:-

Trust - but take care in who.

I take the opposite, trust first, treat others like you want the best for them.

Be so detached from material goods that it would be hard for someone to hurt you, intentionally or not.

Both are the same mindset. Trust but limit the damage is the same as not really trusting.

especially dont trust those you don't like that say "you should trust me"

Turns out that loud music really does damage your hearing.

>what would you advise younger people(...your own younger self)

Labels are meaningless; attach at your own peril - Brands, religions, ideology, all other thought patterns, people - choose local,intrinsic context; what works is all a crapshoot + past generational gifts anyway.

Keep learning; there's always something new and it never gets old learning new perspectives

You can endure much more than you think.

Remember all those challenges and struggles you overcame or failed? This one is no different, but you're still here.

Let go, relax.

Pay attention; your life depends on it.

Stop living in the past; that person/life is different and done or in some other multiverse. Live now with all it's joys and sorrows.

Outdoors and nature: she always heals

Bonus insight: you become more invisible and that has opportunities!

With sufficient age, cancer is highly likely to rear its ugly head. After a certain age, waking up without pain and enjoying the simple things in life like good food, conversation with family and friends, a laugh, etc. are a gift and a blessing.

Can't tell you what it's like, that would spoil the surprise. Advice: take good care of your teeth and skin. Avoid impacts, broken bones or serious strain injury. Minor injury you receive when young will become more aches and pains as you age. Keep your back strong and straight. Lift with your legs. Wear hats and long sleeved shirts when your going to be in the sun for a long time. Treat your friendships and romances seriously, the embarrassments of your mistakes will be with you for a long time. Fill your memory with as many beautiful things as you can, it makes reminiscing more enjoyable. Don't talk so much!

"I highly recommend getting older! There's less tendency to people-please."

"As I started getting older, I realized, 'I'm so happy!' I didn't expect this. I wasn't happy when I was young."

-- Jane Fonda

Advice #1: You are what you do every day. Choose to be something good and do it every day. An organizing principle of time management is that all we have is our time here. What you do every day should rarely appear urgent and you may find it difficult, but if it is what you want to be, it sustains focus and peace of mind.

Advice #2: Associate with people of the highest aspirations who live lives of character and integrity according to strong moral and ethical standards that you can admire. Solitary virtue is often futile, and I wish I had given people less credit for being interesting.

1) save/invest $ aggressively. Financial independence has huge benefits in the near-term and long-term. You don’t need most of the crap you’re buying. 2) if you choose to have kids, make spending time with them priority #1. There is nothing more rewarding. 3) immerse yourself in nature frequently (without much gear) 4) find opportunities to work/volunteer/friend with people from a diverse array of backgrounds 5) listen:talk 5:1 6) amen to dental care comments 7) learn continually about a wide array of topics

On romance:

It's better to find someone who likes what you are than try to become something you're not.

Robert A. Heinlein Quote: “It's amazing how much 'mature wisdom' resembles being too tired.”

Make friends. Keep friends. Making new friends get much harder when you are older.

Difficulty in making friends as one gets older isn’t actually a result of age, in my experience. I think as people get older they tend to be in fewer situations where friends are easily made. If you put an older person in, say, college, they’ll make friends just as easily as they would have when they were younger.

To a point, no all nighter benders will be possible or at least easy.

And then you'll find much fewer people interesting, and more people annoying. That's a function of knowing more.

amen, impossible

Try to eat well. I had no 'dietary education' from my family (basically it was an "eat what you like, when you like") and at 44 I fiscally felt so bad that I went to my doctor saying "I need to be checked as I think I have something really bad". I went through a number of checks and I was fine. This was also worsened as I am not obese, so I did not connect in a first instance my feeling bad with my eating habits. I decided to loose some weight and I put myself on a quite silly diet since few months now. I am eating mon-fri one time every 24 hours. Basically I have a meal a day (a dinner) and any junk food or sweet has been banned. I have lost weight (and I'm still loosing about 800/1000 grams per week) and I feel great now. My second advice is to pick a job which aligns with the things you enjoy doing. This will not necessarily lead to money, but still you will enjoy it. Consider we work the majority of our time.

There is nothing silly about this “diet”. Don’t let anyone make you feel bad or silly for it. This is how humans evolved. There are dozens of health benefits to eating once per day (or less). We are chronically over fed and under nourished. Fasting or OMAD like you describe is about as close to a cheat code for life as I’ve found.

Thank you for your comment, appreciate it

I would add that healthy diet is not something complicated. I wish I know about it much earlier.

Here is the basic concept: https://www.hsph.harvard.edu/nutritionsource/healthy-eating-....

Just split your plate (approximately of a hand size in diameter) on 4 parts: 2 parts vegetables, 1 is protein/meat, 1 is for carbs (should not be overcooked, just slightly undercooked to not transform it into fast digesting food). Spoon of healthy oils.

Thats it, 3 times per day. Nothing more, nothing less. Here is my diet for the last couple of months and this is the most impactful thing to the quality of my life besides walking every day at least an hour.

Do you get it that he said his diet is silly to avoid people trying to explain him how to diet, right? But nobody fasting really believes that eating 3, 4, 6x a day is the right choice. Even more with 3 servings of carbs (one fully digestible, 2 not).

Bill Gates Sr. answered the question this way: I can relate to the answer the late Bruce Bliven, a former editor of the New Republic, was reported to have given when someone asked him what it felt like to be an old man. He said, “I don't feel like an old man. I feel like a young man with something the matter with him.”

How do you avoid, prevent or postpone getting "something the matter" with you? I second what others in this thread have said: attend to diet and exercise, take care not to injure your eyes, ears, back or knees. Diet might be the most important place to start - have a look at https://gamechangersmovie.com/

One of the crazy parts about being older is how time feels different. 10 years ago seems like yesterday, but when I was young that seemed like forever. It doesn't seem like the world changed much until you actually think about the details.

I'm about 60. My early life left me with no confidence that I would make it this far, so by the time I was 21 I was getting ready to die.

What it's been like to grow old

* My body's in officially lousy shape, but I don't feel much worse than I did at 21. Sure, arthritis makes music harder, and being fat makes it hard to tie my shoes. For some reason, though I know I should feel worse, I don't really.

* When you literally wake up glad to be alive every day, and I have done so for half a century, minor things like your body betraying you or someone else's political leanings take on much less importance.

* I am never, ever bored. There are so many things I want to learn, so many products I want to create. I have never known a programming language so well that it bored me, because I always used them as vehicles to get something interesting done. They are tools to me. Like any craftsperson, good tools are important but they are always subservient to the product.

* I have been fighting a losing battle with weight for 50+ years. It's terrible. I am ashamed that I'm morbidly obese and dependent on diabetes and high blood pressure pills. Every time I go out I'm embarrassed to be fat. Every thin person I see is a rebuke, unless they're smoking. (To me smokers are honorary fat people.) Don't fucking tell me to eat right and exercise right and sleep right. I fucking know it. It's just hard and I never stop trying.

* I have been a horrible insomniac for 55 years. I figured by now there would be a cure for it. A good night of sleep for me is 3 1/2 hours. A bad night of sleep is 20 minutes. 3 1/2 hours is not enough for me to feel good for most of the day but it's enough to get essential work done.

* After a traumatic brain injury when young, my memory went bad. Consequently I have always been a slow learner. I have probably suffered some cognitive slowdowns but I don't notice them at my age. Learning is hard for me now, but it was hard for me at 21. I just have to work harder than anyone else. Fine with me! I chose work I enjoy.

* I still have absolutely no problem pulling all-nighters when the project interests me.

Things I saw that other people didn't seem to see as much

* By the time I was 14 I had observed that SV-type jobs were cyclical. Even though I wasn't tech-oriented then I realized if I ever got into a tech field I'd have to keep up in order to remain relevant. Decades and many millions of dollars later, I still keep up. I have worked for myself for the last 21 years but I still act as if I may need to get a job at Google tomorrow. I still study every night (in my case, Go, py4web, and database infrastructure).

* Whenever I got a job, I assumed things might get bad so I always stayed within bicycling distance in case there was a gas shortage or something.

* I saw that two-income families often contained two people who came home with a need to share their stress, but also take care of the kids. This results in neither one wanting to listen to the other, and the resulting tension harms family life. So I made a deal with my wife that one of us work, and one stay home. Didn't care which one (turned out that I was the worker, and we both like it that way). Also I married someone who understood that sometimes I have to work hard. We planned to be poorer than our friends, but the opposite happened. I was able to get ahead by studying at night and trying out different ideas.

* From a very early age I saw that some people got hit hard by "unexpected" events like high medical expenses or business failures. I knew I would either have to safe very carefully (like Asians, who make up most of my family) or be a good earner. I ended up being a good earner who doesn't save as carefully as he could. Result: I spent $40K/year on insurance premiums and can easily absorb it. I own several houses outright and have no debt.

* I never had a "special" way of treating women I dated. There was never a me-who-buys-flowers vs. a me-who-ignores-her-once-we-get-married. I always dated women I liked to be with during daily activities, like shopping or doing the laundry. I just never take the people close to me for granted. Of course I buy flowers for my wife after being married 30 years, and it's always because they look like good flowers, not because it's a day merchants tell me to buy them.

* I read history. I understand how long empires last. I love America and its values, but I fear the mob. So I own lots of guns and have always lived in places that felt defensible.

* You know those old movies and stories where the person is given a second chance on life and appreciates people around in a new light? I have always been that way. My wife, not so much. So we see our children differently. To me they are enormous treasures and (not recommending this, it's just me) even though they're all adults I live in abject fear that something bad happens to them.

What would I advise younger people to do? Well, my most successful idea, I think, was to figure out by 25 what my core values were, because everything comes out of that. In my particular case, it went:

* No one cares about your job more than you do. For me this led to the understanding that I should start my own business. You don't have to and, more important, may not want to! But I feel it's less risky than working for someone else. If you don't do that at least save up for a rainy year (below)

* Be a decent citizen

* Treat people different from me with respect

* Try to admit when I'm wrong

* Treat my kids with at least as much respect as I would treat Bill Gates or a cop or a waiter, and be as polite to them as I would be to anyone else

* Do work that wouldn't embarrass my kids if they told their friends about it

* Being rich is good because it helps with independence and safety buffers, but it's always subordinate to taking care of the people I love

* Expect people to be motivated by their base instincts, and by incentives. People are neither natively good or bad, so be ready for them to be bad. That means understanding your core values and sticking to them

* Take logical risks you can afford and be ready to learn from them

* Feel free to cut harmful family members out of your life. I will guess that I went through more than my share of bad stuff when young. This left me with a very simple rule. Family is important, but it's also what others make of it. I would give family members who harmed me an explanation of why I felt bad, then ghost them if nothing changed. Nothing ever changed. Do I feel bad after they died? Do I feel like I should have connected better with the people who raped or beat or neglected or abused me or accused me of horrible things I didn't do? Absolutely not. I have never regretted removing harmful people from my life, family or not

* When you're evaluating doing something big, the more you like it, the more you should try to talk yourself out of it. You should be super honest about both the potential upsides and the potential downsides. Project what would happen to you a year after the worst or the best happened

* Expect bad things to happen. Easy for me to say now? Sure, but I was totally ready for Covid by the year 2000. Completely. So were observant Mormons and many Chinese people

* Avoid debt

* Have at least a year's living expenses saved in case of unemployment, unrest, etc.

Obviously YMMV, but because I wanted nothing more than to escape from my childhood home/school life, by 13 I had read autobiographies of famous achievers and had crystalized these values based on their successes and mistakes. I developed as a way of escaping the present. It was either that or kill myself. I'm very glad I didn't kill myself but I needed some logical reason to have hope.

> I have been a horrible insomniac for 55 years. I figured by now there would be a cure for it.

Unless you're really unfortunate, there's a cure for insomnia. It consists of several simple but not always easy-to-follow rules: https://insomniasos.net/

After years of suffering from insomnia, I've started sleeping better 2 weeks ago.

[Edit: Sorry I know you weren't looking for advice, just can't resist sharing]

Thanks for the share. Interestingly, I began almost the identical program--two weeks ago. My sleep has gone from about 45 minutes a night to 2.5-4 hours.

I had tried all of these things before, but when I consulted my sleep doctor he pointed out something that changed my life. Previously I had tried to wake up at say 6 or 7am, on the theory that if I'm going to bed at 9-10am anyway, what does it matter if I try to wake up early? It would be horrific either way.

But he recommended a later wakeup time (10am) and to roll it back a few minutes a week. That single change made the difference.

Thanks for caring. I've bookmarked the site.

Last night I had a pretty rough time but in general things have looked up a little each day. Biggest improvement I can remember since trying sleeping pills, which only work for a month or so on me.

Thanks for the thoughtful response. You sound just like one of my good friends.

My grandma is turning 107 next month. She is still in perfect shape cognitive wise and in reasonable physical shape for her age. When you have lived for so long, you have an interesting perspective on things. I think what she would probably tell you is that the most important thing in life is to be independent and to be able to adapt to changes. Everything is temporary. Anything you take for granted right now is gonna be gone at some point. Any person that is currently in your life is gonna die at some point. Death is really the only constant, and you have to be okay with that.

Echoing some of the advice in this thread, Christopher Hitchens said (possibly quoting someone else) something along the lines of "It becomes increasingly obvious that you can't make new old friends".

Avoid becoming addicted to anything (e.g., don't consume unhealthy illicit substances). Get enough sleep, sunlight, and exercise. Also, make sure you adopt a healthy diet where you remember to also consume things that will improve your gut bacteria so that your body thoroughly absorbs all those healthy nutrients. Of course, if you don't care how long you live, you can ignore all of the above advice. Some people say they don't want to live forever, but I've yet to encounter anyone who was happy to exit this world like a satisfied diner at a restaurant.

Be in service to someone or something without expecting anything in return.

For me it is my dog.

"My goal in life is to be the kind of person my dog thinks I am."

Unless you don't like your dog, this ironically just sounds like an excuse for caring about no one but yourself.

I don't understand. Could you elaborate?

How I see it, taking care of a pet usually requires lots of effort and selflessness. You need to make sacrifices and stay consistent. E.g. with a dog, sometimes you have to go for a walk even if you'd prefer to stay at home and watch TV. All this seems to me the opposite of taking care about only yourself.

For me it is my God. :)

Fund your retirement.

Don't waste time with romantic partners who don't love and respect you.

Don't waste time with people who don't have your best interests at heart.

Get as much education as you can handle and ask for help along the way.

Surprised a search for caffeine doesn't find anything on the page.

Having given up soda around college (and never getting into coffee, and rarely drinking alcohol), almost 20 years later I'm glad I have the ability to drink just a little bit and get a good short burst of energy.

Treat caffeine as you'd treat aspirin, or bandages, especially when you're younger and you really do have an efficient power generator, and ability to do more with less. You'll have less of a tolerance you need to beat to get the same effect when you're older.

I can't speak to caffeine, I'm still trying to kill that demon myself.

However, cutting out alcohol has increased my health and energy significantly. In your twenties you can drink every day, wake up at 8:00 and have a normal day. In your forties, that catches up with you.

You still feel the same as when you are in your twenties. In fact in answer to the the question "How old do you feel?" I always feel like I'm about 22.

However ..... for some reason you can't do as much. Some jobs that you could do all day once upon a time now leave you exhausted after an hour or so. Those hills seem steeper than they look. That package is heavier than you thought it was. I suppose I'm trying to say that your body hasn't maintained the same youthfulness as your head has.

Be careful with diet and avoid any extreme diets. I went on a low calorie diet for a couple of years and lost weight, but I ate a lot of a generic pudding product that turned out to contain a lot of titanium dioxide that I believe caused me to get sick with the rare yellow nail syndrome and now I have compromised lung function rather like CPOD. Another thing that is much more important than people realize is gut microbiome. Have fun while you can - don't leave it until later.

Don't listen to other people.

Also: Don't ask for advice on HN.

Don't put off experiences. Thinking "I'll do that later" when you have an opportunity now is a recipe for never having that experience.

I'm 43 and I recently had a reasonably bad bike wreck. The recovery time for cuts and bruises really surprised me, compared with inline skating injuries in my 20s. I can definitely tell the body isn't working as well as it did.

(1) Trust your instincts. Really listen to that inner voice.

(2) I forget.

No wait! I remember! Be really careful who you have kids with (see item (1)). Most mistakes you can walk away from, but when an innocent human life (or two) is involved, you don't get to just reset.

(3) Bonus free advice (NOW how much would you pay?): Invest for the long term. Consider total return. Don't try to time the stock market.

keep a journal in plain text

I started doing this recently for fun about a year ago, and boy am I glad I started doing it. Will do it forever from now on. It's fun revisiting entries.

Things you will regret - not having had enough sex, not spending enough time with friends, not putting money aside for your pension. You will also wish you'd been kinder to your parents. You will wish you'd learned how to be kind to yourself and you'll always regret not taking better care of your body.

63yo here. As you get older, a lot of things get easier. For example public speaking. It's terrifying when you're young. But at this point I consider myself well-read enough that I could talk to any group of people about any topic for ten minutes without breaking a sweat (or being paralyzed by fear and indecision).

What stands out to me as I’ve aged are the people I’ve known, the memories of experiences with them, and the times I’ve given and received the kinds of help which benefit lives. None of these things compel me to words of reminiscence, but remembering them brings feelings of grace and gratitude.

I hope this does not come across as too sentimental.

I am 38 years old, and I can see my parents getting more frail every day.

Talk to them while you can. I could not shake off the teenager-like attitude of being too busy to spend quality time with them for far too long and now I regret it.

As I got older, the list of important things/questions that matter to me got smaller and smaller, finally left with only one question, "how do we really explain a mind?" afraid that I may not have an answer in my lifetime!

One thing I say is have zero expectations of anything and everything then your life will be great.

When i stopped having expectations then I did not add any complains when someone i loved did not behave/respond the way I like it and was happy.

Wear a mask. Most of the “young” I see don’t seem to care, think it won’t affect them, or are fine getting the ‘Rona because they are confident they will weather it. Help other young people learn that it’s not all about them.

I thought you were speaking figuratively at first. Wouldn't surprise me for someone to say that.

I don't feel nearly as smart or "outstanding" as I did when I was younger. But I don't think it is because I have gotten much less smart or outstanding. I think my perception has become more accurate.

Optimistic failures are so common, that I assume every idea/business/etc. will fail, and I'm right most of the time.

That doesn't mean you will fail, but it means I'm not going to be particularly excited.

Your question seems to be mostly concerned about the human body, so you probably know the answer; eat healthily most of the time, exercise regularly, make sure you regularly get good sleep.

Oh, and wear sunscreen.

Seek out mentors, make connections and keep them. These are often more valuable than technical skills. Of course, making such connections and acquiring mentors is a lot easier if you're effective at what you do or distinguish yourself in some way, so skills and accomplishments are also very important.

Seek out experts in the fields you're interested and start a correspondence with them and meet them if possible. Ask their advice about things that interest you and that they are experts in.

Many times in your life you will be faced with a choice between the hard road and the easy road. Most people take the easy road to mediocrity. You can further distinguish yourself, learn a lot more, gain more skills, and grow tougher by choosing the hard road.

Learn something thoroughly. If you are an expert at something you will be in demand. Generalists and jacks-of-all-trades get a nice, broad perspective and can make connections between fields that narrow specialists can't, but usually it's more feasible for specialists to broaden their horizons than for a generalist to become a real expert, especially later in life.

Be persistent. If you can master the skill of doing that which will improve your life and the lives of others no matter how unpleasant or boring that task is, especially over the long haul, then you will accomplish much more than most, who tend to easily give up and move on to something else.

Related to this, whenever you start something that will take a long time to finish, expect that there will be boring, frustrating periods where everything will seem hopeless. Plan well ahead of time what you'll do to overcome them when you'll encounter them. This is a place where your mentors and experts in the field can help, as you can ask them for advice when you run in to a roadblock.

Surround yourself with people who bring you up, not try to drag you down to their level or who are completely unmotivated. Always try to be around people who are smarter than you, who are better than you at something you're interested in, and who you can learn from and be inspired by.

Don't study for the test, but value knowledge for its own sake, to learn useful skills, and to improve yourself. This connects to the next crucial point:

Read A LOT. You can gain many lifetimes of experience through books. Real books, not blog post and tweets. It would not hurt to start by reading through "the classics", but often lists of classics overlook much excellent foreign literature, so try to seek out the best of what different cultures have to offer.

Travel (when the plague is over). Few things can open your mind to what is possible, let you meet fantastically interesting people, have unforgettable experiences, learn about other cultures and ways of being, and open up new opportunities for you than travel.

On the subject of travel, I would advise you to go off the beaten path and avoid super touristy areas. Stay in hostels.. it's a fantastic way to meet people and can save you a ton of money too. Don't try to see too much at once, and try to stay in one place for a good week or two, if you can, instead of doing 7 countries in a weekend.

Once you've traveled a while and got a taste of many different countries you're bound to find a favorite. Try living there for a year or two. You'll get a perspective on the place that a quick visit will not give you, and let you use it as a base for exploring other places in the area, and you'll gain even more valuable connections there that you couldn't as a mere tourist.

Learn some foreign languages. This is yet another way to make great connections and get to appreciate other places and cultures at a level you couldn't if you were just monolingual. It'll also open you up to the literature of other countries on a level you just can't get by reading it in translation. Many books don't even have translations, so you'll be at an advantage there too.

Learn to like yourself, enjoy your own company, and be your own best friend. Always seek out new subjects to learn and new teachers to learn from. A great teacher can make anything interesting.

Exercise and take thorough stock of what you're eating to make sure you don't have any nutritional imbalances. This can greatly affect your mood and energy levels, and ultimately let you live a lot longer and with many fewer debilitating conditions than you'd have otherwise. A sure way to physical misery is to not take care of your body.

Finally, try to help people and be as useful to them as possible. Apart from this being the right thing to do, it's also a lot more fulfilling than being purely selfish, and people are usually glad to be of help to someone who's helped them. So by helping others you'll be helping yourself.

Have you seen "Being 97"? [1]

1) Start your pension planning as early as possible.

2) Maintain friendships outside your main relationship.

3) Spend time with your children.

4) Look after your physical and mental health. Eat good food. Get exercise.

My only advice, don't listen to advices, nobody has figured out this weird thing we call life.

Not true. You can learn from experience, either your own or others (the latter is better).

Remove all negative people from your life. I wish I had done this from school time onwards...

Man, I'm not even that old yet - but feel old, I guess. Pushing 40.

At this point of my life, I can definitely say my outlook will change in 20 years. 20 years ago I would have thought my belief systems to be set in stone more or less. If this is true, you will miss a whole lot of personal growth. It may depend on the person but I've certainly developed a whole lot more empathy and benefit of the doubt for people I would not have had in the past. I've also learned the world is a whole lot harsher and nicer than many would report, and humanity/society is a very complex thing. 99.9% of the world wants to hug you, not hit you, is something I always try to keep in mind.

A lot of this is based on what you expose yourself to though, so I've noted it's pretty easy to "grow" in the opposite direction if you never get out of your "early 20's" bubble of high school friends, or if you get "stuck" in a such a rut early on in life too scared to make the next step.

The largest lesson I think I've learned is that almost all my regrets have to do with inaction vs. action regardless of outcome. I highly regret many things I was too lazy/scared/talked out of doing, but even the things that turned out (at the moment) absolutely horrible that I actively participated in with my best effort I do not regret now in the least. At the worst some were learning experiences, most turned into (via completely unexpected ways) amazing experiences and opportunities. Note that this can mean almost anything - relationships, work, life experiences, travel, etc.

I guess all I can really give as 100% "for sure" advice is I have never regretted anything I've truly given 100% of my effort into. I've only regretted the moments where I've half-assed something. And this is regardless of outcomes. If I can go to my grave saying I did my best and tried to make my tiny corner of the world better - I'll be quite happy.

That and the mundane daily positive personal habits you can get into the earlier the better. You make yourself a far more attractive partner if you take basic care of yourself like doctor and dentist visits, basic daily hygiene, and at least making an attempt at eating healthy/being active. Others have covered this far more than I have, but I certainly endorse their advice. I simply wanted to point out it goes beyond your own personal health - your health is important to others in your life and for me at least it was easy to forget that for some time.

Also something I haven't seen said a lot here - surrounding yourself early with positive friends who share your values/aspirations in life is exceedingly important. I firmly believe in the "you are the average of your 5 best friends" theory.

Vote.

I had this same question after being surprised when I needed reading glasses and when single strands of mutant hair sprouted from various places (eyebrows, neck, etc). My parents passed when I was a young adult so I didn't have many older people around to ask about these kinds of topics.

You focused specifically on physical health. Others have given good advice (teeth, hearing, etc). I'd add several other points:

-- At around 50, your chances of getting cancer hit an inflection point on the "hockey stick" growth curve [1], so you need to get regular (annual) screenings. A good health plan is helpful; when I was on Kaiser HMO they were really good about following up on this. [1] https://www.cancerresearchuk.org/health-professional/cancer-...

-- Exercise doesn't have to be intensive to work well. I rarely go to a gym now; when I was younger, the overhead of going to the gym made me think I had to workout for an hour or more, but in my case it backfired, bc it led to a gut reaction of "ugh" whenever I thought of the gym. I'm pretty committed to hiking, so now I walk outdoors (mineral sunscreen, of course) for an hour per day and that's enough. If you can choose to live somewhere where you can do this year-round then do it. That alone is transformative. When I first started hiking, my knees would hurt, especially going downhill, but after a few painful hikes, it eased up and now many years later my knees never bother me.

-- Highly-suggested weight training books (e.g. Starting Strength) insist on free weights, barbells. I find that 30 min of body weight circuits (and dumbbells) 3x/wk is plenty. Just get into the habit. The benefits accrue over time, whereas you'll see peers your age or younger neglect this and that neglect also accrues over time. Most people don't add 25 lbs of belly fat in one year, it's more like 2-5 lbs per year over decades.

-- Most my friends are younger than me and alcohol is still a big part of socializing, but as I get older I dislike the effects more. Not that I drank much in the first place, but now I've cut back even more. On average not even once per month, and never more than 2 drinks per occasion.

-- Diet is obviously important. Michael Pollan's advice: "Eat food. Not too much. Mostly plants." I still eat too much meat but include greens in every meal. My advice is to cook. As I got older I started cooking at home more. Over the course of a decade I eventually worked up to cooking every meal at home. It helps to establish the habit if you have someone (spouse, family) to cook for, but now I have the habit, it's easy to cook for myself. When you cook, you can eliminate added sugar. All processed food has sugar in it, so I cook everything from scratch. It sounds like a pain, and when I was younger I would never have imagined myself doing it, but when you practice it, you can do it quickly. I eliminated sugar on weekdays. If you follow David Sinclair's longevity advice, you'd cut out sugar entirely, but I still partake on weekends.

-- So far I've been super lucky and have no major health issues/struggles. I'm "old", but not elderly. I still do long distance treks. People I meet are always surprised at my age and energy level. The biggest tell is white hair, or dry scraggly hair. I used to think I'd be interested to hear health issues from people in the 70-90 age range, but I suspect it's so different for everyone that it wouldn't be that useful. I believe there's enough longevity advice out there that if you pay attention to the right sources then you can see what's coming up and what you should be doing.

Not too old yet, 45. But learned many things already because I did a lot of things. Hope to learn a lot more; let’s do this again in 10 years here. Anyway;

If you have enough money, stop trying to get more and live your life instead with your family and friends. Apparently it is really hard for people who gathered a few 100k/million (depending where you live) to just let it be and enjoy. Moreso (as I understand) in the US than in the EU. In the EU you hardly need money to begin with depending where you live and want to live; Where I live, all my neighbours live of around 500/mo. As a wfh software dev, 500 is literally a few hours work. And that would be me alone working from home; my wife does too... The always trying to get more and buy crap turns out, when you get older (and friends/family starting to die off/get ill) you understand it really does not matter at all. But then it might already be too late to correct it, even with all your cash. It is hilarious to me to read all these ‘time managed’, mostly Americans on here; every second of their day as efficiently managed as they can. And for what? Go outside, walk in a forest, talk to strangers; Running the same time managed wheel every day; that I find the real waste of time trapped in your own rat cage. I needed to grow older for this though to realise some of it; I never did the timemanagement thing (as I always believed it is sheer insanity; but I guess that is a matter of what you think counts as valuable; I enjoy walking in nature, I do not enjoy spending time in the gym efficiently and eating soylent to save a few hours in my day; those hours are valuably spent on thinking in the forest, chatting with friends in the sun on the square etc; then I use 4-5 hours to write code, which I already worked out in my head while walking; for backend and firmware coding, that is far more efficient than just ramming in as many chars as you can and then trying to run it; also something I learned as I got older; I am much faster in delivering than my young colleagues; not because I am smarter but experience and thinking shit through before just hammering it in and letting unittests tell it is wrong; I find that an actual utter waste of time) however I did miss important events I should not have missed because I was working for a few extra bucks. Events that will never repeat.

Ofcourse we are lucky to be able to work from home and people who do not want to move to a different/cheaper place obviously have less choices, but also that gets easier when getting older, at least in my experience. The city becomes less interesting; freedom and space more. With covid we saw here that indeed people are not that married to their cities and their cramped appartments: lot of houses sold that were empty for years; now suddenly they have almost no cost of living (even going to a restaurant for a complete meal and drinks costs 6 euros pp if you fancy that) and space to breath. So the money earned in the ratrace suddenly might get you well into retirement and then there are state pensions and hospitals are free anyway. Especially if you have a house or mortgage in the city, you can sell it and that’ll keep you good for 20-40 years if you don’t buy rubbish. Or you can rent it out and you are good basically forever. Not that I like that personally but I know many who did exactly that so they could retire at <40.

Physically; do fasting and weights; really helps energy levels and pushes back on loss of muscle mass which will happen when you get older. I notice that people who focus less on their wasteline and more on bulk make it far longer in a far more robust way. Skinny muscleless ex runners/cardios don’t do so well when going 80. Obviously do not get too fat, do not smoke/vape(although, ofcourse my entire village smokes 3-4 packs/day and the elderly are in their 80s/90s puffing away while sitting in the full sun for hours without sunscreen, but that is just, I guess, survivors bias), take care of your teeth and when you feel something weird anywhere, go to the doctor. People wait way too long, especially men.

Edit; a more depressing thing of getting older, for me, was seeing how incompetent, lazy and untrustworthy people are. We tolerate blatant lies from ceo’s, cto’s and our colleagues almost every day. From small ones (I will work this weekend for this one time and then ‘my computer was broken but miraculously works again on monday’) to potentially company breaking lies by sales from vendors ‘yes this feature is done and delivered’; 2 weeks before beta; ‘oh did he say it was? no that is done somewhere in 2021 but we do not know when yet). I see it everywhere now; it was always there but it starts to really annoy me now.

Older people THINK they can remember what it was like to be young.

Taking an hour-long walk during lunch is the best thing I ever did for my health and work productivity.

You will become a Conservative.

I have no idea what that means other than you'd probably hate your future self so give people around you a break for their values you disagree with.

You can hate the inevitable change of the world and still embrace it. Doing otherwise is to be in denial.
