I remember reading an article based on a paper that tried to replicate small-scale hunter-gatherer "week". It turned out that "work" was less than 20h per week.
As in: about two days of necessary hunting-gathering was enough to sustain the group for the remaining five days. The rest of the week was for maintenance and leisure (so it's not like five days of staring at the sky; it just that work done during that time was _not necessary to immediate survival_).

That's anyways what I remember.
