There are certain laws of health which deserve particular attention and they are so simple that even a child can learn them. A certain amount of exercise is necessary to keep the body in perfect condition. All the powers (mental and bodily) we possess are strengthened by use and weakened by disuse. Moderation in eating and drinking, reasonable hours of labour and study, enough sleeping time (not less than 7-8 hours a day), regularity in exercise, recreation and rest, cleanliness lay the foundations for health and long healthy happy life.

Thousands of people consider sports to be very helpful in gaining good health. That's why every country pays much attention to developing sports. It is sport that helps to bring up physically strong, strong-willed, courageous and energetic people.

In the last ten years recreational sport has become extremely popular, and, according to doctors is absolutely essential for a long and healthy life.

The reasons of this enormous interest in sport of all kinds are varied. When you ask people why they spend so much time, effort, and sometimes money, they will talk about the physical benefits (feeling fit, increasing stamina, sleeping better, the chance of living a more active life), psychological benefits (self-discipline and respect, a sense of personal achievement, relaxation, getting rid of aggression), and the social advantages (meeting people with similar interests, the team spirit). However, the social aspect seems to be more important for men than for women. Very often, enjoying a drink with friends after the match is as important for the former as a physical activity itself. The latter generally see sport as a way of keeping fit rather than anything else.

They are so-called sport-fans. They pack stadiums during sport matches and competitions, they sit glued to the TV, and they are ready to give every moral support to their favourite sportsmen or teams.
