It's just a cold.
  1. The building where I work.
    Probably covered in asbestos or mold or something equally sick-making.
  2. The sick people who touch things like door handles and hand rails that I also touch.
    I try not to touch them, but I'm also a fan of opening doors and not falling down stairs.
  3. Not drinking enough water, on my part.
    I've got a problem and that problem is an addiction to Diet Coke. Everyone knows water solves all problems.
  4. The damn weather.
    I hate that this crazy weather is turning me into one of those people who talk about the crazy weather.
