“
In fact, for most of the 300,000 years (give or take) that Homo sapiens has been walking upright around the world, we did not work forty hours a week, and we certainly didn’t work more than three hundred days a year. Our working habits changed dramatically a little more than two centuries ago. Modern work hours are an aberration, and we have enough historical record to be able to prove that. Going back as far as 4,000 years ago, to the days of ancient Greece, we find that Athenians had up to sixty holidays a year. By the middle of the fourth century BC, there were nearly six months of official festival days, on which no work was done. Work for the ancient Greeks was carried out in spurts: intense activity during planting or harvest, followed by extended periods of rest for celebrations and feasts.
