—Abe Rosen, Chicago, Illinois Yes! Here’s my favorite, from Tom Georgi in Carlsbad, California. “Why is it nearly impossible to do the following? Sit in a chair with both feet on the ground. Then lift your right foot a couple of inches off the floor and make a clockwise circular motion with your foot. At the same time, try to write the numeral six in the air with your right hand.” Try it, readers!
