Right. I was out about in Japan not looking at infirm 90 year olds at Japanese people’s’ homes. Survivorship bias. That said, we wouldn’t have evolved to live as long as we are we’re it not for a reason. Unless medtech isn’t extending lives (imho its not outside of comatose),

Those old living people must be providing some value to society otherwise they would’ve died much earlier.

Life expectancy was shorter because no one made it past 5 and you got killed when someone else hit you over the head with a rock. Medicine is not extending people’s lives outside of rare cases.

There's a good Charlie Munger story about this. There was a heart surgeon who had amazing success rates with heart surgery for years. Finally someone investigated to figure out what he was doing better? He was operating on people who didn't need it.

Maybe I'm delusional or naive, but I think a lot of heart surgery is unnecessary or just caused by modern unnatural diets.
