That article make sense to me. It shows a random group of Neanderthals who lived 40,000 years ago with an average age of 35.
It then shows a group of adults that lived 2000 BC who lived to an average age of 38 years.
It then shows Iron age ()700 BC to 0) life spans with an average age of ~42 years
Finally it mentions middle ages (to 1000 AD with none living longer than 45 years
Kings from 1000 to 1600AD lived an average of ~49.5 years
Royal court… lived oh you can read it yourself.
Didn’t the Egyptians keep good records?
Sure there was the 6 sigma group who outlived the general population. They were, no doubt, the Wall street traders of the day living off everyone else’s hard work.
