Nice question, ambivalents, and thanks for the recommendation, yesenadam. Very cool. I just started watching the first video of Sapolsky's lecture and found it to instantly capture my attention. I'm going to stick to this series. By the way, studying Sapolsky could also help with the forum question recently in Ask: HN about explaining things well to people.
His lectures look like a neat place to get a deep anthropological grip on things.
