Good health is a boon. It is the real jewel of life, the most precious possession of man. If a man losses his health, the world losses all its charms for him. A good wealth of health can be obtained in a number of ways. It needs regular exercise, good food, good thoughts, and cleanliness. A healthy person does not spend money on medicines and visiting doctors. Just opposite, a sluggish person is another form of hell of diseases. The simplest and most traditional definition of health is that it is the freedom of sickness and diseases. According to World Health Organisation (WHO), a branch of the United Nations, health is physical, mental and social well being and not merely the absence of disease. Next to life itself, good health is the most precious gift and is necessary for a purposeful existence. 'Sound mind in a sound body' is an old saying. Healthy persons can work for long hours without getting tired. They can enjoy all the pleasures of life, whereas unhealthy persons can't. The world has no charm for them. They are always worried due to their physical complications. Wealth has no importance for them. To keep good health no money is needed. It can be achieved only through our efforts and proper health care. We can maintain good health only if we are aware of various factors which affect our health. There are certain things which are essential for keeping our body free from diseases. Nutritious food comes first. We should takeVpnly that food which has nutritious value. Some regularity in life is also important for good health. We should get up early in the morning, go out for a walk, breathe in fresh air to keep our lungs clean and in good order, and take brisk walk, move arms while walking. Maintaining clean habits is also important in this regard. If we don't take bath regularly, don't wear clean clothes, don't eat fresh food, we may develop physical complications in the long run. Hence regularities, good habits and cleanliness have great value in maintaining good health. Balancing sleep and rest are also useful in this regard. We know that a great deal of the waste matter in our bodies escaped by means of the skin, which contains many millions of tiny drainpipes called 'pores'. If we neglect keeping our bodies clean, these pores get choked up and the waste matter cannot escape. Hence we must keep this important point in our mind and do accordingly. Laughter is the best medicine of good health. So, we should keep calm by overcoming anger, greed, fear, envy and enmity. Life of a healthy man is his long lasting wealth. It makes him able to enjoy life to the full. Those who are wealthy may not always be healthy but the healthy people are always wealthy.
