第二十七篇
How often do you sit still and do absolutely nothing？ The usual answer these days is “never”， or “hardly ever”。 As the pace of life continues to increase， we are fast losing the art of relaxation. Once you are in the habit of rushing through life， being on the go from morning till night， it is hard to slow down and unwind. But relaxation is essential for a healthy mind and body.
Stress is a natural part of everyday life. There is no way to avoid it， since it takes many and varied forms——driving in traffic， problems with personal relationships are all different forms of stress. Stress， in fact， is not the “baddy” it is often reputed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control that it can lead to level performance and ill health.
The amount of stress a person can withstand depends very much on the individual. Some people thrive on stress， and such characters are obviously prime material for managerial responsibilities. Others crumple at the sight of unusual difficulties.
When exposed to stress， in whatever form， we react both chemically and physically. In fact， we invoke the “fight” mechanism， which in more primitive days made the difference between life and death. The crises we meet today are unlikely to be so extreme， but however minimal the stress， it involves the same response. All the energy is diverted to cope with the stress， with the result that other functions， such as digestion， are neglected.
It is when such a reaction is prolonged， through continued exposure to stress， that health becomes endangered. Such serious conditions as high blood pressure， coronary heart disease（冠心病）all have established links with stress. The way stress affects a person also varies with the individual. Stress in some people produces stomach disorders， while others succumb to tension headaches. Since we cannot remove stress from our lives， we need to find ways to cope with it.
