This is silly. But true. Albeit maybe stupid.

Try this:

1. Without anyone watching you (they might think you are goofy), & while sitting at your desk in front of your computer, lift your right foot off the floor and make clockwise circles.
2. While doing this, draw the number '6' in the air with your right hand. Your foot will change
   direction.

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). Do not yell in frustration. Just accept it.

It's weird, because I can move my hands in opposite circular directions (taught to me by an old choir director who was also a drummer), but the foot + 6 thing is just impossible. I tried a few times. I give up.
