Sideband:I started at the top and ended in the loop. I can also point my index fingers towards each other and make a clockwise circle with one and a counter clockwise circle with the other at the same time.
Practically everybody can do this. For confirmation, point your index fingers away from yourself and give it a try. What's really tough is to have them both go clockwise or counterclockwise. This is true even when you turn your fingers to point toward each other or in toward you.
