How do you motivate someone to act for the greater good, especially when it means sacrifice of personal, vested, or special interests? Why on the university campus, can I feel refreshed and able to talk about what I'm interested in with one person and then the next moment talk with someone else and feel like I just played a game of Axis and Allies or practiced manipulative politics talking about the same things? Why in America are women okay getting in bed together but strongly opposed to being naked in front of another woman, and why are men strongly opposed to getting in bed together, but will talk about life and sports while naked in a locker room changing...?
