You cannot do two things at once

[andrewducker]

While sitting at your desk make clockwise circles with your right foot.

While doing this, draw the number "6" in the air with your right hand.

Your foot will change direction.

tried this on the bus when I read it in the paper. I got stared at a lot cos I laughed too much.

My foot did not change direction when it was right hand and right foot. However it did when I wondered what would happen if it was left hand and right foot.

I think my brain must be wired wrong.
