As the pace of life continues to increase, we are fast losing the art of relaxation. 21  you are in the habit of rushing through life, being on the go from morning till night, it is hard to  22   down. But relaxation is  23   for a healthy mind and body.

Stress is a  24   part of everyday life and there is no way to  25  it. In fact, it is not the bad thing that it is often supposed to be. A  26  amount of stress is important to provide motivation and give  27  to life. It is only when the stress gets out of control  28  it can lead to poor performance and  29  health.

The amount of stress a person can bear  30  very much on the individual. Some people are not afraid of stress, and such  31  are obviously chief material for managerial.(管理的) responsibilities. Other people lose heart at first  32  of unusual difficulties. When exposed to stress, in  33 form , we react both physically and mentally. In fact we make a choice between “34  and fight”. And in more ancient days the choices made the  35  between life and death. The crisis we meet today are  36  to be so extreme, but however little the stress is, it requires the same response. It is when such a reaction  37  a long time, through continued exposure to stress, that health becomes  38  . Such serious conditions as high blood pressure and heart disease have established links with stress. 39  we cannot remove stress from our lives, we need to find ways to deal with it.

So what do you think of  40  ? What is your way to deal with it?
