totally off topic, but...

  • sit in a chair and lift your left leg so your foot is about 6 inches off the floor
  • rotate your left foot in a clockwise direction (only your foot) - and keep it going...
  • now, using your left hand try to draw the numeric '6' in the air using your first finger (starting at the top of the '6' and moving down).

Did you manage to do it ???
