For those of you with some spare time in office...try it. Bet you can't!
1. While sitting at your desk, lift your right foot off the floor and make clockwise circles with it.
2. Now, while doing this, draw the number "6" in the air with your right hand...your foot will change direction!
Why is this so? Answer from Science Made Simple:
"The left side of your brain, which controls the right side of your body, is responsible for rhythm and timing. The left side of your brain cannot deal with operating two opposite movements at the same time and so it combines them into a single motion. Try this with your right foot and left hand and you should have no problem!"
