I have always been interested in hypnosis. I did a paper in high school on alternative medicine, and one of the stories I used was about a doctor in South America who did surgery with only hypnosis as the anesthesia, and the patients reported no pain. I'm not sure I'd go under the knife with hypnosis as my only painkiller, but it was very interesting to me, just like acupuncture or biofeedback is as well.
