How smart is your right foot?

Well, this is actually a forwarded mail I received recently. I'm posting it because I found it interesting. You have to try this. I guess there are some things that the human brain cannot handle.

1. While sitting at your desk in front of your computer, lift your right foot off the floor and make clockwise circles.
2. Now, while doing this, draw the number '6' in the air with your right hand.
Your foot will change direction!!

Tell me if it doesn't!
