this one came from my nephew in Illinois ( USA)
Just try this. It is from an orthopedic surgeon...How smart is Your Right Foot?
This is so funny that it will boggle your mind, and you will keep trying at least a couple more times to see if you can outsmart your foot, but you can't. It is 'preprogrammed' in your brain.
1. WITHOUT anyone watching you (they will think you are STUPID... J ) 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 direction. I told you so, And there's nothing you can do about it!
You and I both know how stupid this is, but before the day is done you are going to try it again, if you have not already done so.
