Life expectancy thousands of years ago was in the mid to late 30s, with high infant mortality, trauma, and infection, though some individuals lived into their 60s.

“So, let's use thousands of years ago before before the advent of any medicine at all. So admittedly they weren't living that long and admittedly um you know life expectancy would have been into the mid to late 30s. Um but people always confuse that for meaning nobody lived beyond that. Of course that's not true. It just means so many people died young, right? Like infant mortality was through the roof. Tons of trauma and infection. But clearly there were people that were living into probably their 60s and I'm sure some of them were dying of cancer, right?”
