Pain

Pain is nature's unpleasant but crucial way of warning you of danger. It stops you repeating any action that causes pain. Touching something painful activates an immediate withdrawal reflex. Some people are born with an absence of pain - a very dangerous condition because they do not realise when they have hurt themselves. Sometimes people lose their feeling of pain, for example leprosy sufferers, who can severely damage their hands and feet as a consequence.

Reflexes enable you to avoid getting hurt when you feel pain.
