This is from an  orthopedic surgeon….......... it will boggle  your mind and you will keep trying over and over again to see if you can outsmart your foot,  but, you can't.  It's pre-programmed in  your brain!

1.  Without anyone watching you (they will think you  are GOOFY......) and  while sitting at your desk in front of your computer, lift your right foot off the floor and make clockwise circles.

2.  Now, while doing this, draw the number '6' in  the air with your right hand.......Your foot will  change direction.

And there's nothing you can do  about it!
You and I both know how stupid it  is, but before the day is done you are going to  try it again, if you've not already done  so.   :rotfl:
