I 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 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.
