I know, it sounds like a bizarre topic, but it could be interesting anyway...
Me:
I can't snap my fingers, whistle or blow bubblegum bubbles.
I've never voted (I'm 40 years old).
I don't watch network television except for either major sporting events in which I have a vested interest or if there is a major news event (e.g., 9/11).
I never stop at those stop lights at the end of freeway entrance ramps (have done it literally tens of thousands of times w/o any negative consequences. Ever.)
