8's and 0's

Benefits: Aids concentration. Makes you laugh or smile (I hope). Connects the two cerebral hemispheres. 

Actions: Standing with feet shoulder-width apart, raise your right arm to chest height. Draw a sideways figure 8 (infinity symbol) in the air with your right hand. Do this a few times, and then - 

Your Challenge: Draw a circle in the air with your left hand, while you draw the 8 with your right hand.  Draw at least 4, and then change sides: do a circle with your right hand, and sideways 8 with your left.  Interesting? 
Repeat the sequence at least once more.
