I'm sure you know an axiom: "Sport makes people healthy". No doubt, that's true, but frankly speaking one knows that there are some kinds of sport which you cannot go in for if you are not healthy enough. Say, body-building. If you have a heart decease or other sickness, attending the body-building trainings will bring you nothing but harm. And also, going in for sport is always connected with a great risk, because any athlete can get an injury. And we know many examples, when an athlete got trauma at the beginning of his sports career and in the prime of his life had to leave professional sport. But it doesn't mean at all that people shouldn't go in for sports. I only want to say that they should be careful and remember that the health is given to a human being only once, so, do your best not to lose it
