     Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about

our diets, our bodies soon become loose and fatty and our systems slow moving.

     There are some aspects (方面) of our unhealthy lives that we cannot avoid. I am thinking of such features

of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects

of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport

or other. While it is true that every weekend you will find people playing football and hockey in the local park,

they are outnumbered a hundred to one by the people who are simply watching them. 　　

      For those who do not particularly enjoy competitive sports - and it is especially difficult to do so if you

are not good at them - there are such separate activities as cycling, walking, jogging and swimming. What

often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are

doing yourself much good, except for the fact that you have at least managed to get up out of your armchair. 　　

      Even after you have found a way for keeping in shape, through sport or gymnastics, you are still only

half way to good health, because, according to the experts, you must also master the art of complete mental

and physical relaxation (放松). It has to do with deep breathing, emptying your mind of all thoughts,

meditation, and so on. Yoga, as practiced in the West, is the most widely known and popular of the systems

for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have

improved in a material sense we have found it increasingly necessary to go back to forms of activity-physical

effort on the one hand and relaxation on the other - which were the natural way of life of our forefathers.
