Fascination
i am fascinated by the almost perfect coordination between hand and eye. i take the key out of my pocket and stick it straight into the keyhole, never missing. when i want to press "5" in the elevator, my movements are perfect and i always hit the "5" -- never the "3" or "7" or any of the other adjacent buttons. i reach out to grab the coffee cup, and even early in the morning i always manage to make an accurate estimate of distance and direction and grab the cup by the ear, instead of hitting it and pushing it off the table. or almost always.
i find that fascinating.
