In fact, it is not the bad thing as it is often (36)supposed to be. A certain amount of stress is (37)vital to provide one with motivation and give (38)purpose to life. It is only when the Stress gets out of control that it can lead to poor (39)performance and ill health. The (40)amount of stress a person can with stand depends very much on the individual. Some people are not afraid of stress at all, and such (41)characters are obviously prime to material for managerial responsibilities. Others lose heart at the first signs of (42)unusual difficulties. When exposed to stress, in whatever form, we (43)react both chemically and physically. In fact, we make a choice between "flight" and "fight". In more primitive days (44) 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. (45)It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart disease have established links with stress. (46)Since we cannot remove stress from our lives, we need to find ways to deal with it in order that we can stay healthy in mind and body.
