Would this study hold for ancient societies thought? There is very, very little we know of pre-historic societies. Early farmers did not have pesticides, or advanced machinery. They were working with crops only recently domesticated, and with little knowledge of best practises. There was no social order, so bands of thieves may have been more common. This would suggest that much time would have been spent weeding and protecting crops from pests and thieves, although there can be only speculation on this part. However, I would be cautious of accepting that ancient societies had it as good as the people in the study. Once societies formed it probably got worse, eg. the life of a farmer in ancient Egypt.
