>As in: about two days of necessary hunting-gathering was enough to sustain the group for the remaining five days. When things go well. Then a random famine appears, and your descendants (what few survive) write horror stories about it for the next few centuries. Or maybe none at all, because they grew up feral illiterate orphans. Modern society's longer work week is the "insurance" against the modern version of that. Without even knowing it, you and everyone else is invisibly squirreling away "extra" to keep yourselves from starving if things turn to shit. Unemployment insurance, savings, social safety nets, robust (even frantic) economies that have an excess of job openings.
