This will boggle your mind and you will keep trying over and over again to see if you can outsmart your foot, but, you can't. It's preprogrammed in your brain!
1. WITHOUT anyone watching you (they'll think you're GOOFY) and while sitting where you are 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.
I told you so!!! And there's nothing you can do about it!
