I’m talking about before we figured out we could grow vegetables and fruits. Early humans are often shown as being fit and in shape, yet our diet pretty much only consisted of meat. We were hunters. So why the hell were they so fit? I thought a healthy diet mattered more than just being active constantly?
fit? possibly - or not, art of fit healthy people sells better than art of average slovenly people. artists need to eat too.
fitness aside, our ancient hunter/gatherer ancestors didnt live very long - hunting/gathering for survival is not a task that engenders longevity, especially when you’re tens of thousands of years away from discovering metal.
and then when we discovered farming/animal husbandry, we started having issues with diseases & plague. the average lifespan didnt noticeably increase, despite there being less active threats (baring war and famine, of course).
