At Southampton Solent University (formerly an institute), England you can get a degree in animal healing, which is putting your hands on an animal and pretending you're connecting "energies". It's amazing what the education system is coming to. I say healing is a load of rubbish, though I do think you can convince yourself through self-determination out of something. With things like acupuncture, on Braniac:Science Abuse (good TV show ^_^) they managed to make a man give up smoking with pretend acupuncture which was using a geometry set and a man from the local chinese. The man gave up smoking, but these results could have been faked. Acupuncture and other such treatments give people the sense that they can give up/get better because they are being helped, and gives them the force of will required to get better/give up.
