Kenpo:
Another excellent book for you to check out (if you haven't already) is: "The Healing Brain" by Robert Ornstein, Ph.D., and David Sobel, M.D. I don't know if it's still in print, I bought my copy years ago. Published by Simon & Schuster. It's a really good book which explains alot about how all of this works, belief system, the brain functions etc.
Interesting thread!!!!!
