Drugs

are illegal in sports so sometimes the sport organisations make blood tests after the competitions. Many good sportsmen and sportswomen were caught taking the drugs. There are many kinds of drugs known and some of them are not detectable. Drugs are not the only the one unhealthy stuff in sports. Some of the sports are unhealthy themselves. Every sport could be unhealthy, but some of them are really dangerous, for example boxing, hockey, American football, act. Most of the professional boxers have problems with their bodies when they get older. Their hands are shaking and many of them have problems to think like a normal people anymore. There isn’t only a risk of physical problems in boxing, but mentally also.
