I don't know. I think hunting, gathering, music making, story telling,
tool making, surviving and living outdoors might use a person's brain
even more than what's happening for a lot of people these days. That's
the sort of use the big brain evolved for in the first place. Maybe
people now tend to have more stress rather than more brain activity.
