Abstract
Even the most stable brain operates just a millimeter from madness. Stress is the body's way of responding to any kind of demand. It can be caused by both good and bad experiences. Many different things can cause stress - from physical (such as fear of something dangerous) to emotional (such as worry over the family or job.). Stress can be caused by overwork, anxiety about exams, money, job security, unemployment etc. Many changes that are apparently ?for the better', such as being promoted at work, going to a new school, moving to a new house, and getting married, are also a source of stress. In biology the term "stress" is generally used to refer to the bodily response that occurs in the presence of challenges to psychological and physiological homeostasis. Industrialized countries are now faced with an increasing burden of stress-related disorders.
