• People who live a hunter-gatherer lifestyle today live 65+ regularly. The average may be lower for uncontacted peoples for various reasons, or higher because of reduced disease transmission. I imagine it depends on the group.

    Now, I will give you that humans have refined their techniques of hunting etc over that 90k years in a way that caused less accidental deaths.

    The crux of the matter though is that the statistical averages you have seen are flawed by infant mortality. In these societies, if you made it past toddler age you were statistically likely to live a long time.

    What would be killing people much past their “prime” and how do you define prime?
