High quality backpacks and hiking boots are around $200, and tents are easily double that. If you’re going on hikes that pose a realistic chance of getting stranded, you’re probably pretty serious and already paying for premium equipment. In which case, another $300 for peace of mind shouldn’t be a dealbreaker.
For anyone who clicked this thinking this would be related to model validation, it ain't. The article is promoting test-driven development for systems that have an ML component.
Snowboarding, downhill skiing, mountain biking, and any martial art. These are from personal experience, I’m sure there are plenty of other examples.
Even weight training, which is an experimental group in this article, when done properly, requires high levels of neuro-muscular coordination and development. I am always weary of studies that evaluate “strength training” because there are so many different approaches with wildly different outcomes. Let’s just say that a max effort squat by an athlete with around two years of proper training emphasizing technique requires a hell of a lot more coordination than busting a move on the dance floor. I’ve been weight training for 15 years and I still feel like I am learning something new every time I get under the bar with the right mindset. The mindset part is key, because if you are just going through the motions then you’re not developing new skills. But I would bet a lot of money that top level strength athletes would say that their form is far from “perfect” and that this the area that affords the biggest opportunity for improvement.
This is the part where I’m going to be brash. Unless you tell me exactly what defines a strength training regimen in your study, I will assume it’s something along the lines of curls and lunges done with tiny dumbbells over a large amount of reps. Especially if your study calls it “repetitive”. There’s nothing repetitive about proper strength training. Every rep that’s done mindfully affords a unique learning opportunity.
Sports simply too complex to categorize in simple terms like “dancing” or “resistance training”. In the context of experimental design, our definitions have to be much more precise.
Having said all that, this is how I interpret this article: “Learning complex motor skills that require high levels of attention is better for the brain than doing 100 curls with 3 lb dumbbells.” And my response to that is “no shit”.
There is plenty of reading material on this.
I wish US cops would enforce anything but moderate speeding and rolling through stop signs.
I’m actually really frustrated with these changes and would like to start using an alternative. I like startpage but they use google search results so that’s not a viable alternative. Guess I’ll have to check out duck duck go’s Bing powered performance.
In a strict sense, you’re right, our diets don’t require meat. But most people wouldn’t consider it practical to take the 5-10 different supplements needed to replace all of the benefits of eating meat, fish, eggs and dairy. And that approach is almost certainly suboptimal to whole food sources anyway.
But yes, glycine also has many of its own benefits. Including a very interesting theory regarding life extension due to its interaction with methionine. [2]

I’m not necessarily talking about demographics, but rather clickstream data, and anything categorical that you can get your hands on. You join that to your CRM and build a model to predict buyers. A really good predictive dataset for marketing purposes is simply a list of time stamps and names of visited domains. With the right feature engineering, that becomes an excellent proxy for demographic data, current buying appetite, and a whole lot more.
At the end of the day, you don’t even necessarily need to know what the data means as long as it’s predictive. And there are plenty of brokers out there who will let you test their data for free with an agreement to pay if you end up using it at scale. All of this revolves on using PII for matching.
I’m sure what you’re saying is true for some marketers, but there are billions being made on PII keyed data.
Say what?? I’ve also worked in the ad industry and deanonymized personal data is shared and sold routinely. You speak of statistics and large segments but every advertiser I’ve interacted with is either doing individual-level targeting or striving towards it.
This idea sounds patently false and I can't find a single source to support it.
According to Wikipedia, the total US expenditure on Lend-Lease was 48 billion, with 31 of those going to Britain and 11 to the USSR [1]. But saying that D-Day was delayed as a result of the sheer quantity of aid sent to Britain would still be incorrect. Nearly the entirety of Soviet economic aid during the war can be attributed to the U.S. It provided the bulk of the actual raw materiel and effectively paid for the rest through the funding British production. Now combine this with the fact that Roosevelt and his advisors were pushing to open up the Western European front in 1942, a year after Lend-Lease had gone into effect, with Churchill winning out in opposition to the idea. It simply doesn't make sense that the cost of aid to the Soviet union was even part of the equation.

The rest of us on the other hand would be anywhere from a little to much much happier if we had student loans, mortgages, kids' educations, and retirement savings all taken care of.
The prospect of having to slog through life in a glacial pursuit of these things fills me with dread. For me there isn't much of an option beyond becoming successful as an entrepreneur. It's not even so much about the money but having complete ownership. Having to work until 65 running a mildly successful business that I built seems like it shoild be much more gratifying than slaving away to enrich others.
The article also gives sound reasoning for why metabolic stress, i.e., overeating, eating crap and not exercising, could be the most common cause of chronic inflammation. I would guess that psychological stress is another big factor given it's known ability to exacerbate autoimmune and inflammatory conditions. So the cure for most cases of chronic inflammation is going to be the usual mix of diet, exercise, sleep and stress management. We already know that these are the most effective preventative measures against age-related diseases and this research gives us a better understanding of the underlying mechanics.
