Ok, good. I just wanted to get it clarified. It wasn’t personal; I just remember believing as a kid that people died at 30 years old commonly 100 years ago and that technology/medicine has allowed us to INTRINSICALLY live longer… and believed it for a LOT of years, until one day it hit me, “Why are all of these ancient people living for 80-90-100 years?”
Then I realized, “Oh. They’re talking about diseases and things and numbers and populations.”
I still hear it from people, even on places like the Science Channel, about people living longer now than ever before… but without the qualification that it’s “on average” and that they’re talking about large populations, not _individual_ life spans.
Rarely is “typical human lifespan”, unbothered by disease or illness, ever talked about – anywhere.
So, I can’t give you a source. It’s just something I noticed.
