Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.

    Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.

    The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.

    We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.

    Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲劳).

    It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.

   Good exercise--- jogging

Every day, in all kinds of weather, thousands of men and women jog.  Jogging means running slowly. Do you know why jogging has become so popular? Most people begin jogging because it is very good exercise for all people, young or old, strong or weak, and heavy and thin. Jogging makes the heart stronger and helps people lose weight. It can also help them feel better about themselves.

Tips for you to jog

  Should you jog, too? If you want to jog, you need to ask your doctor whether you can jog or not.

Jogging may be too much exercise for you if you are not strong enough.

  Does jogging cost much?  No, it costs almost nothing. But it is very important to have a good pair of shoes for your feet and legs.

   How fast should you go? Jog with a friend and talk to each other while you are running. If it is difficult for you to talk, you should run a little more slowly because you’re running too fast.

How far should you jog? Remember not to go too far at the beginning. You should walk, not run, the first few times. Then do some short jogs for time. After that, do some longer jogs. Maybe in a few years, you can run over forty kilometers as thousands of people do.
