Old People in the Olympics: Swimming

So, as you all probably know, the olympics are starting in less than a month. Of course, there's like a bazillion awesome athletes. Some of them incredibly young (not really because we're the same age), like Shawn Johnson, and some really old. Yeah, I'm talking like in the 40's. Can you seriously be a world class athlete at the age of 41? Apparently. Her name is Dara Torres, shes a swimmer and has been to 5 olympics. She has a kid for god sake, and she can still swim faster than all of us. Some of her teammates were born AFTER her third olympic debut. Yeah, she was born in 1992. That makes her 25 years older than her teammates. All I gotta say, is props dude. You must be some sort of superhuman to be competing with people my age and beating them.
