Here's another "what's my brain doing to me?" piece of weirdness for you to try...

Reads: “While sitting at your desk, 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.”

Hmmm. If you keep trying can you eventually overcome the natural tendency to change directions? I can't seem to do that.
