(Okay, first get your minds out of the gutter!)
What have you got to lose? Just try it.
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 pre-programmed In your brain!
Without anyone watching you (they will think you are 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.
Now, while doing this, draw the number "6" in the air with your Right Hand. Your foot will change direction.
And there's nothing you can do about it!
You are going to try it again, if you've not already done so but the results will be the same.
