Just try this.
It is from an orthopedic surgeon............
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. While sitting at your desk, lift your right foot off the floor and make clockwise circles.
2. Next, 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!
You and I both know how stupid it is, but before the day is done you will try it again.
