Stress, Testosterone, Free Will

Been following Sapolsky for years. Excellent stuff on stress, behavior, and a hundred other things in neurobiology that he covers. The testosterone bits are really well known now but nevertheless he gives a nice summary in his classic, matter-of-fact way. He also touches on estrogen and other hormones and endocrine disruptors too. I just love the mix of animals and humans in his language and his exploration of near zero free will.
