3. Moving limbs in the opposite direction
Here’s an experiment. Move your right foot off the ground and move it in a clockwise direction. Now, try to write the number “6” with your big toe. You don’t need paper or pencils; just write the number in the air with your toe.
Most people will notice that without even thinking they’ve started moving their foot in the opposite direction, partially because the number features a counter-clockwise circle. Some people are exceptions to this rule, either because of the way their brain is wired or because of training.
