As a casual observer I look at these events as though everyone is already on some form of drugs. I have no doubt that in 10 years we will hear about the likes of Bolt, Blake, Wiggins etc being investigated for something and I won't be shocked when some (most?) of them are found guilty. What's the arguement against steroids, EPO, HGH etc though? That it allows people to push beyond 100% of what is 'natural'? How do you define that? If Cadel Evans woke up the morning of a race and took a panadol would that be cheating? That headache might have prevented him winning the race but because he took an un-natural substance he was able to compete at a higher level than what his body would've 'naturally' allowed. What about the AFL players who get pain killing injections during games? Are they cheats? If it's too painful to play without pain killers then shouldn't stay off the field? Races, events, matches, games, whatever you watch or whatever you call it, everything has been decided by some form of chemical stimulant or suppressor taken by one or more participants so I say go the other way - open slather for any and every advancement of the human body. Low oxygen training, blood doping, gene manipulation and of course, every kind of needle, pill and anal seppository known to science. Go the whole 9 yards. I don't care if guys are juiced up to the eyeballs with bull shark semen, if they manage to run a sub 9 second 100m race I will still have my mind blown!
