I would also ask everyone to think about who is influencing these athletes?
Ok here is my story which I hope expresses my point:
For the record I had some pretty serious surgery and have never 100% recovered. The reason? I bought into an NCAA system that believed it was more important for me to be an all-american and be the "tough" captain. I remember telling both my trainer and my coach 5 weeks before NCAA XC that my ankle was really bothering me. Now if I had of been smart and not bought into the whole "captain" role... I would've stopped running and healed up for track. Instead I ran conference, regionals... and finally NCAA's. I could barely walk without pain in the end.
My reward? My coach didn't even give me the time of day or talk to me meaningfully one last time before I graduated. Partly because once he figured out I wouldnt be running for the team in the spring he moved onto his next recruit and next fast kid on the team. Would I do it again? Heck no! If anything this contributed to the end of my racing career and also left me bitter for 1 year before I started to think about it differently.
My cheesy conclusion:
I am 100% sure there are some athletes who buy into the whole country pride and money thing (agents, dirty doctors). Sometimes it will take atleast a couple of years removed before you can realize the stupid moves you are making. Atleast I just have a weak ankle... it be a lot worse had I doped and my heart was fried now!
So if you don't have a problem with doping, please, do realize something.
With age does come some type of wisdom. You begin to realize when you raced it wasn't about the plaques, watches, etc... and more about the teamates, experiences and sense of pride from working hard towards a goal.
However if kids begin dopring before they realize this. I fear a lot of people will be waking up 10 years down the road sick, with bad livers, etc. Kicking themselves because they made dumb decisions and followed to ideals of people who are "pro-drugs".
