My uncle sent this to me today and I thought it was so neat:
Ok! How smart is your right foot?
Just try this very simple experiment. It is from an orthopedic surgeon.
This 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're going NUTS) and while sitting where you are 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 directions. Go on try it again, but this time really concentrate.
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 haven't done so already
