Sitting at your desk, lift your right leg off the ground about 6 inches, and rotate it in small “clockwise” circles.
At the same time.
Take your right hand, and start rotating that in small “clockwise circles”. (Simultaneously with your foot)
At this time both your foot and hand are doing small “clockwise” circles.
Now, try to rotate your hand only “COUNTER clockwise” while your foot is still going clockwise.
You can’t do it.
Here's another.
Try to keep your X at 55 mph on an open highway.

The foot trick is harder.

Scary. And we are the same mammals who fly the space shuttle, supersonic passenger jets, build microprocessors, the Hubble space telescope, race cars/bikes, and prepare food for consumption. Makes you wonder dont it? :twisted:

I failed at both accounts. But I don't mind failing at the second one.

What... ?

WILL an X stay at 55 on an open road? Does the owner's manual tell one how to make it do that?

Yeah, well I dare ya to touch your elbow with your tounge!
