Challenge you

I came across an interesting situation when tried this simple task. I put this challenge to my blog readers.

• Sit down on seat
• Lift your right leg
• Start rotating your right foot clock-wise
• Also lift your right arm now
• And start drawing circle in anti clock-wise direction through your right hand
  

The challenge is that you can not rotate the right foot clock-wise and right hand anti clock-wise at the same time. Your foot will automatically change the direction to anti clock-wise. Its amazing and it is a proof that how much man is helpless in case of built-in instincts and restrictions.
