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.
