Armstrong... Worth it?

Seven tour titles and an Olympic medal down the tubes.He finally gave it up.I wonder if it was worth it?I know that the going notion is that everyone in the era was juicing it in one way or another. In the end I don't doubt that.Sport is man against man. (Or woman against woman for that matter) It's the training and skill against training and skill. It's not who has the better chemicals.Whatever dude... some way to make yourself a bit irrelevant.
