Most Native Americans had a standard of living not much better than stone age neanderthals. Thirty years old was old to them. Even the most advanced societies before modern power had 95% of their people doing subsistence farming, tied to a spot of land for their whole lives performing back breaking work until they couldn't do it any more and then died.
I'd still like to shoot for a higher standard of living. At least until I die. Then the rest of you can live like feudal peasants if you want.
I wasn’t talking about farmers.
Farming is an unnatural economy. It is an early example of making more of less when overpopulation reduces the supply of free wild game and produce.
And I’m not so sure 30 years old was old to them.
There were (and maybe still are) hunter gatherers in their 40s and 50s more fit than fat modern man.
Thor Hyderdahl, for example, spoke of a native Polynesian who was still climbing cocoanut trees late in life.
Columbus was astonished by the fit bodies of the natives he encountered.
Average lifespans of hunter gatherers seem low until you factor-out the death rate of children: once reaching adulthood, many lived vigorous lives into their 60s. I remember reading that the average lifespan of adult African Bushmen in the 1950s was as long as that of the average American in the same period.
