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 of our unhealthy lives that we cannot avoid.I am thinking of such features of modern city life as pollution,noise,reshed meals and stress.But keeping fit is a way to reduce the effects of there evils.The usual suggestion to a person who is looking for a way to keep fit is to take up some sports 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 particuarly enjoy competitive sports--and it is espscially diffcult 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 leisure 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 sports 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.It has to do with deep breathing,emptying your mind of all thoughts,medition,and so on.Yoga,as practised in the West,is the most widely known and popular of the systems for achieving the necessary state of relaxation.It seems ironisal(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.
