Good health is really like a wealth. A healthy man can enjoy his life. But a sick person cannot enjoy good food, cannot travel and cannot play games. We must take care of our health. Flies and dust carry hundreds of germs. They are enemies of our health.
Flies sit on food and sweets and fruits and make them harmful to health. So we must not eat open food, sweets, and fruits. Moreover, we must try to kill mosquitoes which carry the germs of malaria. We must spray D.D.T. and germicides on still water and dirty places where mosquitoes and germs breed.
