More on male hunter-gatherers

There was one other item from the Kim Hill paper that I found important.  It is often said that hunter-gatherers foraged 1 to 4 nonconsecutive days per week.  I've always been a bit suspicious of this.  Without many good options for storing food (especially meat), how would they ensure a daily supply of food?

Kim Hill found that men foraged on 84% of the days.  The only days they did not forage was when there were heavy rains.  So by this math, men foraged almost 6 out of 7 days each week.  This seems more reasonable to me.  It also may imply that the body needs activity virtually every day.  Even on the days when men stayed in camp, they still walked and pursued game for roughly 90 minutes.  For these hunter-gatherers, there were really no "days off".
