A Healthy Lifestyle consider that man’s health depends on his mode of life. To prevent the diseases it’s necessary to keep some simple regulations: to go in for sports, to eat carefully, to take a rest and to walk frequently in the open air. I’m fifteen years old and the last three years I do my morning exercises. It inspirits and gives strength to me for a whole day. I add dousing with cold water in winter. I think that conditioning to the cold is the main method for preserving my health. My favourite winter sports are cross-country skiing and skating. I prefer to run in the park and play tennis in summer. I go to the swimming pool twice a week the whole year round. Swimming increases the respiratory system. I also try to observe a day regimen. Every day I go to bed and get up at approximately the same time. I give special attention to meals. I don’t eat fatty and high-calorie foods and I don’t drink heavily gas-cut beverages. At my time of life some peers smoke and drink alcohol but I think that it’s dangerous for a human organism and sooner or later it will be injurious to our health. I think that everybody must begin to take care of his health in his youth because it’s easier to take care of our health than to recover it.
