Thank you grin emoticon Yeah, I think about stuff that I
  shouldn't have to. Like the Paul Exclusion principle. One part
  of me is annoyed that I can't control it. Since I was a kid, I
  imagined I could just make the electrons of body open up like
  venetian blinds and a wall's electrons line up like venetian
  blinds and then I could just pass through solid matter. Seemed
  logical.. when I was 11 anyway. Still kinda does. So, Pauli
  Exclusion principle annoys me because *photons* get to overlap,
  connect and separate and all that but NOOOO, not electrons. At
  the same time, I'm glad for it, begrudgingly. I'm sitting on a
  chair. I'm WELL AWARE that, thanks to the Pauli Exclusion
  principle, my ass stays here. But what if it got turned off? I'd
  go through the chair, the floor, the ground, to the center of
  the earth and just... stay there. So, I'm reluctantly glad for
  it. But then... THEN I'm annoyed because they don't -REALLY-
  know why it works yet. 90 year old idea and they can't explain
  'cept it's a principle. Anyway, the chair thing - if I let
  myself, I'd think it all of the time and never sit down again...
  and be nervous standing.. or interacting with matter at all. But
  I inhibit it, along with 1000 other things not worth thinking
  about. But they crop up now and again. Brain never stops
  churning, for better or worse tongue emoticon
