A brain/foot teaser

How smart is your Right Foot?

Try this:

1.  While sitting at your desk in front of your computer, lift your right foot off the floor and make clockwise circles. 

2.  While doing this, draw the number ’6′ in the air with your right hand.  Your foot will change direction!

Odd eh? But not really surprising, since the brain is pre-programmed against doing it.
