It tends to be because athletes are only in their prime for a very short space of time, their physical and mental endurance needs to be at it's peak when competing in sports. Obviously their are exceptions such as snooker and darts (are these even considered sports?) But that is the usual trend.
Also injuries are very common and can jeopardise careers, even missing a month of training can result in not being able to compete in upcoming events and muscles needing to be rebuilt. Footballers are dropped often from teams because of injury, their managers refuse to pay them for not being able to perform.
Well, athletes only have a limited time where they are in the prime of their life, where they are most physically capable and thus able to perform well in their sport. Too long playing a sport puts someone in risk for being injured, the longer you play the higher the chance of being injured, and the older you get it is harder for injures to heal properly and can impair them from playing. It's usually due to their physical condition and because as the young grow older, younger players come in who are more physically capable than the older players, sort of like how when someone has an older computer that was really great in it's time it can become obsolete. However, that's not always the case with athletes, some are able to have long, amazing careers while sustaining few injuries or are able to fully recuperate from any injuries they have sustained. So, it all depends on the individual, really.
Athletes tend to have shorter careers because they cannot handle the stresses of being in the spotlight. Also, athletes usually have some sort of risk to overcome in their prefered sport. Failing to overcome these risks can result in injury.
becouse they are often pushing them selfs to the limt must of the time and the pick up injurys that you and i would not pick up
Coz keeping ur self not fat is hard work
