Observe how women and men shop and you’ll see that not much has changed.
Women feel fabric, try on shoes with a dress, and ask to see things in different colors.
Men see something that can sate their appetite, kill (buy) it, and get back to the cave as fast as possible.
For our distant ancestors, once the catch was safely back at the cave, the pile never seemed high enough.
Famine threatened with every drought, snowstorm, or pestilence.
So, over-collecting was a smart strategy: the downside of too much stuff was wasted effort.
The downside of under-collecting was death from starvation.
