I've got a nasty cold, which has been retreating and resurging for the better part of three weeks. Today is a resurgent day, prompting me to wonder: why do you feel cold when you're running a slight fever? I realize there's a stronger contrast between your internal temperature and the outside, but I'd be surprised to find that I'm running as much as two degrees of fever, so the contrast can't have increased that much. Can readers comment?
