The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities, others lose heart at the first sign of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact we make choice between "flight or fight" and in more primitive days the choices made the difference between life or death. The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Since we can't remove stress from our lives （it would be unwise to do so even if we could）, we need to find ways to deal with it．
