Men are hard wired to take on the wooly mammoth, an incredibly stupid thing to do, one would think. But, if he wins, the tribe eats through the winter, he is a hero and becomes leader of the clan and women want to have his babies. Not so stupid, after all.
If a women does something stupid and dies, she is dead and someone else has to take care of her children, or they are thrown to the wolves if they are not the children of the mammoth killer. Women are hard wired to raise the next generation of mammoth killers and baby makers.
This is the answer to all of life’s problems, the rest is just deciding which bourbon to drink.
I guess we've never really been hungry.
