Many of you have made some good points here, like i said it before i think it is worth it. I've been involved with serious training and sports since i was a child and as far as i'm concerned bodybuilding is just a sport like any other one. Except i think that bodybuilding is far more demanding than most other sports, you have to do allmost everything to get to the top and even more to stay there. Even if you don't want to get to the top, you still have to eat, train and sleep way more than "regular people."
Btw: i don't think that bodybuilders are as sick as many here do, sure they mega dose on everything (or atleast some do) and they live to "excess" ,but most of these guys are very intelligent and do know what they are doing. I think you could call that "an calculated risk." There are plenty of other sports where drug use is rampant and they use things that aren't even remotely what the human body "normally" has in it. For example many cyclist use drugs that are considered POISON (atleast) in their dosages, just to get an egde and to fool the testers.
I personally think that the worst mistake someone can do with their life is not going after their passion, sure you might fail, but atleast then you don't have any regrets at your death bed. I know so many cases where someone was very talented, skilled and dedicated then something happened and they started to live a normal life. Now i'm not saying that there's anything wrong with that, but all of these people have that "WHAT IF" haunting in the back of their head.
