Geriatric Olympics? Why Not!

I have been watching the Beijing Olympics, and at the opening ceremonies many of athletes from different countries acted like, well, "kids"; laughing, wearing funny hats, jumping around instead of walking, etc.

I wonder, what would the Olympics be like if held for those aged 50 and over? Now, that is something I would appreciate. Many young people are strong, athletic and muscular just because of their age. Someone over 50 would really have to work hard to earn the right to be in the Olympics for those over 50. Now that would be interesting!
