Health is wealth. In the life of a human being health occupies an important place. Preservation of health should be the primary duty of mankind. Health is man's normal condition, his birth right. It is the result of living in accordance with the natural laws, pertaining to the body, mind and environment. These laws relate to fresh air, sunlight, balanced diet, regular exercise, rest, relaxation and sleep, cleanliness internal and external, right attitudes of mind, good habits and good patterns of living. Our ignorance about health continues to be profound There are no yardsticks for measuring health. Health is often taken for granted and its value is not properly realized until it is lost. However, during the past few decades, there has been a reawakening that health is not merely a precious possession, but also a 'resource'. So it is desirable to maintain and promote health.
