But often, it's easier to resist temptation with distraction, or to be so inculcated in doing the right thing that it's automatic, outside the frontal cortex's portfolio - Then it isn't the harder thing, it's the only thing you can do.

The frontal cortex doesn't even fully develop until age 25, which is wild!

Importantly, rather than promoting aggression, testosterone promotes whatever is needed to maintain status when challenged.

Most of us don't collapse into puddles of stress-related disease.

We are just another primate but a very confused, malleable one.
