As you might've picked up, I'm a huge George Carlin fan. Although I don't necessarily agree with his point here, I think it's worth mentioning George's take on steroids in sports:
It annoys me when people complain about athletes taking steroids to improve athletic performance. It's a phony argument, because over the years every single piece of sports equipment used by athletes has been improved many times over. Golf balls and clubs; tennis balls, racquets; baseball gloves and bats; football pads and helmets and so on through every sport. Each time technology has found a way to improve equipment it has done so. So why shouldn't a person treat his body the same way? In the context of sports, the body is nothing more than one more piece of equipment, anyway. So why not improve it with new technology? Athletes use weights, why shouldn't they use chemicals?
Consider the Greek Phidippides, a professional runner who, in 490 B.C., ran from Athens to Sparta and back (280 miles) to ask the Spartans for help against the Persians in an upcoming battle that threatened Athens. Don't you think his generals would have been happy to give him amphetamines if they had been available? And a nice pair of New Balance high-performance running shoes while they were at it? Grow up, purists. The body is not a sacred vessel, it's a tool.
