Came across the website for the world's youngest video gaming professional. A 7 year old boy from U.S. Started playing games since he's 2 (kids play games early these days...) I don't know how good he is, but this kid being in the Major League Gaming (MLG) speaks for itself. There is a website and an upcoming TV coverage for him as well.
If you get beaten by a 7 year old these days, don't feel too bad :)
