Oh, you mean that insatbile hunger that created the very computer you sit by to type this? The hunger that made sure we had medicine and comfort enugh to live beyond the teenages.
Error here: Keep in mind that most of the increases in "lifespan" are due to
kids not dying before age 16 or so. Even in Roman times if you made it to 20 you were pretty much set to live into your 60's.
Nowadays, life after 70 isn't all that great. So you can live into your 80's, but how much additional fun really is there?
