Here is a silly challenge, for when you a break from resting and studying Torah, from a popularly circulating e-mail:
While sitting at your desk, lift your right foot off the floor and make clockwise circles. Now, while doing this, draw the number six in the air with your right hand. Your foot will change direction and there's nothing you can do about it.With a little practice I could over-ride the effect. Very entertaining for a few minutes!
