I've already outlived my ancestors, and the world's a pretty dismal place, or at least the US is, so why not let an otherwise preventable disease take me 20 years earlier?
I had a sort of similar view and then I heard about a boy attending kindergarten in my area with Sanfillipo syndrome. There are different types of it but basically their bodies can't break down certain kinds of carbohydrates which means that they accumulate in their cells and eventually cause havoc. As a result, they continuously lose motor and brain functions until they die at about 20. There are no cures. Him (well, I don't know how much he knows given his age) and his parents would probably kill for more days. It also made me realize that my day to day problems were utterly trivial and that I should be grateful for even having day to day problems.
Oh yeah. Just a little bit of snark-slash-commentary since humans are being treated as profit centers. My FP of 20+ years also retired after selling his practice, as per the article. I do think it's sad (no, I'm not depressed!) that the race to the bottom, with a dash of enshittification, now encompasses health care, which we all need.
There's still a lot of things I want to see and do.
