Here is a real mind-boggler for you. Try to see if you can outsmart your foot.
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.
Did you try it out?, what happened? Your foot will change direction. There's nothing you can do about it. Let me share a secret - you couldn't outsmart your foot, because somehow it's hard-wired in your brain!
