It all begins with physical, emotion, and social well-being. We believe that every adult should understand how his or her body works--muscles, circulation, digestive, skin, eyes, ears and so on. Why and how we process food, gain and lose weight, maintain good health, age and more. Then, there's the brain: we should know how our brains process and retain information, and each of us should possess a reasonable theory of the human mind--our own and other people's minds (which are clearly different from one another).
