Can outsmart your foot? You may think you can, but, you can't.
It's pre-programmed in your brain!
1. Without anyone watching you (they will think you are retarded) and 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.
DOH! Your foot changed directions didn't it! And there's nothing you can do about it! You and I both know how stupid it is, but before the day is done you are going to try it several more times, with no success.
