I wish everyone would just get over it (not you guys, but the public in general). You wouldn't have believed the angst the Ben Johnson 'scandal' caused up here in Canada. It received more attention and was more serious than the government misdirecting billions of dollars. Absurd.
People have been cheating since the dawn of time. Nail files or sandpaper in a ball cap, a spitball or whatever could be done. The juice or versions thereof have been around at least since the early 70s and probably prior to that. Take a look at some of the athletes at the '76 Olympics

Blood doping or who knows what else is common place. It's not restricted to any one nation or groups of nations, it's everywhere. Sorry, but only the US has held the high and mighty, we don't do it position. Trust me, Carl Lewis and all his ilk will die early regardless of whether they wore the Union Jack, Stars and Stripes or a Hammer and Sickle.
If people are stupid enough to screw with their long term health for the sake of personal or national glory, let them. I just don't want to read any sob stories or
he/she/they cheated and I'm clean stories any more. All of them are full of ****, plain and simple. I've known hockey players that are on the juice because they think it will give them an advantage. The sport is irrelevant.
And you cannot possibly have a clean and dirty set of events because some ******* in the clean group will turn around and try to cheat. Morality is in the *******, nowhere more than in sports (ok, maybe TV

). If someone wants to compete clean, good for them. I'd say they're smarter, they'll likely live longer but will make marginally less money. I'd suggest it's a fair tradeoff.
