Just thought I'd add my two cents on the brain issue: The myth that we use 10% of our brains is just that, a myth. It was first started by 1930's carnie psychics who claimed to have "tapped into the other 90%". That's not to say there isn't a lot of untapped potential, but that comes from making stronger and more efficient neural connections by training certain parts of the mind. For instance, I once read a study where they performed brain scans (maybe MRI, not sure) on buddhist monks who had spent years on awareness meditation, and found that the part of their brain involved with awareness was considerably more developed than the average person. Quite simply, because they excercise it hard and excercise it daily. The brain's just another muscle.
