Tiisetso Maseloane  asked the Naked Scientists:
Good morning Chris
Can you please explain to me how this happens or how can it be done(in Green)?

Why the brain can not find that rhythm of the hand?
Please chris explain this to me why is this difficult?

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

This will confuse your mind and you will keep trying over and over
again to see if you can outsmart your foot, but, you can't.
It is pre-programmed in your brain!

1. 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.

What do you think?

You only think that it is difficult because you have not taken the time needed to do it. How long did it take you to learn to sit up? Probably about six months. I bet you could learn this skill in much less time if you applied yourself seriously

I tried and drew a reverse 6, a mirror image right off the bat and kept the foot i n a clockwise motion
There after I could not concentrate on it.
I was easier to use right foot and left hand with just a few practices.
Training practice on a bias.

UI can do it easily with right ankle going clockwise and left hand making a 6 in the air without much thought. But...right ankle right hand no way my able does a very quick switch in  a counter clockwise direction!
