Humans are pretty fragile, but I assume you do mean that their ability to metabolize stress hormones follows in ratio.

I don't know if we would do better or worse, 3rd world countries seem to do alright even despite horrible horrible environments which force them to mature faster.

Cant be worse than slowly making the entire world uninhabitable, right?

Yeah but they were also made to think that aging a year every day was normal, and never questioned it.

We'd probably just go on as usual, like we did for thousands of years before we had decent medicine and understanding of diet. It's only really the last couple hundred years that people started to live really long.

I think a key point would be people realizing that they're going to die. It would be less painful perhaps because it's so inevitable. We're going to have to live with the reality of death in a way that no one under the age of 80 does today that I know. Young people today (under 40) generally honestly believe they are going to live forever, or at least so long death is not worth worrying about. Nor any cause for a sense of urgency.

The gods are watching: Have you ever made any plans that include your own death?
