How smart is your right foot?

A Kiwi* cousin of mine sent me a forwarded email this morning. Here it is word for word..

You have to try this please, it takes 2 seconds. I could not believe this!!! It is from an orthopaedic surgeon..... .......

This will boggle your mind and you will keep you 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.

I told you so!!! 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.

[* As an aside, Kiwi is the nickname used internationally for people from New Zealand, as well as being a relatively common self-reference. The name derives from the kiwi, a flightless bird which is native to, and the national symbol of, New Zealand. Spelling of the word Kiwi, when used to describe the people, is often capitalised, and takes the plural form Kiwis. The bird's name is spelt with a lower-case k and, being a word of Māori origin, normally stays as kiwi when pluralised. Thus, two Kiwis refers to two people, whereas two kiwi refers to two birds.
