You are looking at the word "sport" in too much a physical way..there is no real set in stone way to explain a sport. Chess is a sport. Just because you are heavy set, means nothing about you being in shape. I have a person on my paintball team who is heavy set and he can still make the runs, and still dive into the ladder/snake if he needs to. Sport isn't about the physical nature of games. Sport includes physical nature, the mind. In any sport, you need to think and react. you can't just do that when your in shape. These sorts of things include your MIND!

No offense to you in anyway. We all have the right to our own opinions. But I honestly think it's a bit on the ignorant side :-/ .
