The power of the mind. We are told we are going to be made better, some are very convinced. Parents do this with children everyday i.e. "You will be alright", plus, "Don’t be silly there is nothing wrong with you". The placebo effect is proved to work by releasing chemicals in the brain, which can be seen by a MRI scanner – fascinating! Religion, as a re-enforcement of in the mind does work. Religion, though, does not need to be present at all! Any person ‘acting’ as the faith healer will do – as long as the patient thinks that they may be cured : it could then happen! This sets off certain chemicals in your brain. Much more research is required!
