And I can enjoy life for longer if I don't live in a house with lead paint or e̶a̶t̶ ̶s̶c̶r̶a̶p̶s̶ ̶o̶f̶ forget my teflon pan on the stove.

I dislike platitudes like these that don't acknowledge that life is about tradeoffs, and sometimes a little caution gives large rewards.

I've had a few close family members pass from cancer. I was a caretaker during these times for them. Talking with them, changing them (people are really heavy!), feeding them, medicating them, bathing them, etc. We had very good hospice support and paid a lot for it, but during the pandemic, everything kinda went to shit, so it was up to me and a few others most of that time.

Dying of cancer is unique to every person and their cancer's progression. But, from my own experiences, dying of cancer is a fucking horrible way to go.

The pain is quite bad as it colonizes various nerve bundles and organs. Morphine only does so much and wanes as the person gets addicted to it and requires more and more to get the numbing results. As such, your mind goes with the morphine intake, a welcome relief really. You can lose function in your limbs and bowels too, though not always. You stop eating and drinking, but you don't stop thirst and hunger. Death really does become a welcome relief after enough weeks/months of this. Then there is the just normal health hazards and pains of laying down and generating filth. The rashes and sores, the muscle loss, the boredom. It's quite horrible. And that's with loving family members helping you at a moment's notice. One pro-tip here, if you can get a death doula.

Look, I get the sentiment here. Yes, live your life, don't worry so much about how it's going to end. There's likely nothing you could have done different anyway. Your end is going to really suck, no matter what. Better to have it be quick and as painless as possible.

But, I do want to advocate for taking common sense measures about carcinogen avoidance. Those are absolutely worth the time and effort. Do not smoke, don't have lead paint in your house, don't be stupid or lazy about getting these things away from you. Your future self will be very thankful you did that. I know, I've helped dying people who didn't.

Yes but some forms of death are a good deal worse than others. Many cancers in particular can be an awful way to go, especially when it's happening with your full knowledge of its inevitability and lack of ability to do anything about it. I'm not going to give up something I enjoy (or even the indirect benefits of using a particular substance) just to live a few extra years, but if doing so significantly reduces the chances of a drawn-out painful death, then there's surely an alternative worth looking for.

"Not living life also causes death."

Well, if you sit around all day and don't move much, sure. You will shorten your lifespan by a lot.

Or you'll live long, boring life anyways since you have good genes. Nothing in life is certain.

Don't you want to take a leap of faith? Or become an old man, filled with regret, waiting to die alone!

Sure, but you should also probably avoid asbestos.
