I've tried this several times today. I've asked co-workers to try it too, and the result is almost always the same!  Give it a try and see if your foot can outsmart your brain:

1. Lift your right foot off the floor and make clockwise circles.

2. While doing this, draw a number 6 in the air with your right hand. Your foot will change direction.

If your foot outsmarts your brain, let me know!
