Is sport good for health?

Generally many people will agree that the practice of sport（Quebec Nordiques）
is a good thing for health. But is really the case ? A moderate practice of sport（San Diego Chargers）
is certainly a very good thing , but an intensive or a professional practice is a entire different matter. For example（Calgary Flames #12 Jarome Lginla Red 30th Anniversar）if we consider the life esperancy, we can see for example (but they are others)
that professional americans players（2010 Olympic Team Canada #35 Sidney Crosby Red Newest）have a life experancy of 56 years wich is not great indeed. The case of the Sumo in Japon is worse, it's rare that a sumo live more than 50 years (but they have a semi-god status and all the women they want
（Montreal Canadiens #31 Carey Price Blue ） ... Hey beautifull loser dont you want to be a sumo ). Concerning Soccer (european football) many of them have their knees destroyed after years of practice. The doping also, is a very bad factor, which can explain (Pittsburgh Penguins #87 Sidney Crosby Black ) but not totally this diminution of life esperancy. The debate is open : let's enter the AI' s champions in the arena !
