Anthropologists have shown that even in the most inhospitable environments like the deserts of Namibia or Botswana, foragers and hunter gatherers could easily feed everyone in their group and still have 3 to 5 days per week leftover for engaging in such extremely human activities as gossiping, arguing, playing games, dancing or travelling for pleasure.

Such primitives and savages. 3-4 days to laugh, frolic and fornicate.
