Athletes are - I'm sorry - overrated. Yes, it is great that they can do what they do, and I'm happy for them that they achieve their goals. But I'm just as happy for some local kid competing at ping-pong and winning, there is not much class difference there (in my opinion).

Lolita took all of four months to type. It took years to create. (Phelps swims 100 yards so fast because he's trained for years.)

Without Nabokov, Bach or van Gogh though, we'd all be a little poorer.
