Wanted to share this. The whole series -- amazing. Been watching it all summer, some parts over and over. This is the last lecture -- if you get time, watch it, even if just from 38 minutes on. The whole great wisdom of perspective and tolerance, things we need to have to go on. Sapolsky. What a teacher. Love him. http://www.youtube.com/watch?v=-PpDq1WUtAw&feature=player_embedded#!
