Oh man, I have to go up the first stair left foot first, or gutters, if walking, and i scuff my right shoe, I have to scuff my left, sitting on the couch, if my wife it tapping her fingers, and she taps me say 3 times on the left arm, i have to tap the right arm 3 times, to feel 'even', left leg in pants or shorts first, left sock on first and left shoe on first. Its left first in reverse order too. Counting, geez. I could tell you how many steps from one part of the workshop to another, how many steps from home to the corner shops ^^not telegraph poles though^^ If I did, and I lost count, I would have to turn the car around and start from a landmark, and count back on the way home.
I have more, but dont want to sound like a freak......or is it too late.
Oh wait, when I get on or off a aircraft, I have to 'pat' it (like 'thanks or good job) but that only applies when I fly in them, not work on them.
