英语翻译

One reason why people who are physically fit to live longer is that they do not put the heart under excessive strain and so they reduce the risk of heart and blood-vessel diseases. They also avoid suffering the consequences of weakened muscles ,which are the cause of a great deal of back and abdominal trouble.

About 640 muscles for about 45% of our body's weight. they must have the ability to store energy and be continually supplied with fuel by the blood. Sensible exercise,suited to each individual and preferably undertaken on the advice of a doctor,is the best insurance for meeting these requirements
