Too bad you stopped at "part of your education" based on a single presentation.

I have studied the entire history of human evolution, including the drastically debilitating shift to settled agriculture, which was the point - everywhere it occurred around the globe - that stature (height), overall health (measured by the pelvic index), infections (indicated by bone lesions) and longevity all declined precipitously, and dental carries (tooth decay) went from 5% to 25%.

"Mean, brutish and short" describes the life of the "civilized" British during the medieval period and into the early industrial revolution.

Hunter-gatherers, both extinct and extant, generally enjoy a far more leisurely and pleasant lifestyle than modern humanity, replete as it is with epidemic depression and suicide, chronic diseases that are the direct result of scientific medicine and excessive longevity, and constant striving for what can never be achieved.
