This will boggle your mind and you will keep trying over and over again to see if you can outsmart your right foot, but you can't. It's preprogrammed in your brain!!1. 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!
This has been annoying the heck out of me for the last 20 minutes. Give it a try.
