Chinese "Brain Age" game

My sister forwarded this to me:

http://flashfabrica.com/f_learning/brain/brain.html

Instructions:
1. Click on "start."
2. Wait for 3, 2, 1 countdown.
3. Memorize the number's position on the screen, then click the circles from the smallest number to the biggest number.
4. At the end of the game, you will be told how old your brain is.

I've been getting a 20 pretty consistently... :-P
