yeah thought i was the only one with this kind of stupid thing. when going by car to somewhere(passanger seat) i hold the breath when car is passing a street light unless im talking with someone. gets annoying after a while.

Other thing is if I see a huge outside temperature meter or an offer ill have to do some basic calculations.
I.e if the tempretature is +19, my head automaticly goes "1+9=10, 10*10=100, 100+100=200", you get the idea.
