So far this winter I haven’t had a cold, or at least nothing more significant than the sniffles that come from being out in the cold and stepping into a warm building which always seems to cause my nose to run. I’m not sure why this is. Even when it’s been really cold outside it hasn’t, as far as I know, been cold enough to freeze my sinuses, and even if it were I don’t think the temperature change is enough to cause such immediate thawing. If it takes the microwave at least five minutes just to get the frost off a small chicken breast I have no idea why the linings of my nasal passages, which should be a pretty stable ninety-eight and a half degrees Fahrenheit most of the time, can go from solid to liquid before I even have a chance to shut the door that divides the indoors from the outdoors. Some might think I’m inviting disaster by bragging that I haven’t been afflicted by the rhinovirus, or even the elephantvirus, the zebravirus, or the aardvarkvirus. That last one combines sniffling and sneezing with uncontrollable laughing because it’s the only known virus that has bunny ears, a pig’s nose, and a big floppy tail, but that’s another story. I’m not worried that talking about it will cause me to fall under the influenza, mostly because I’ve never been really superstitious, knock on wood, but also because I got a flu shot at the start of the season and I think my odds are pretty good even though the flu vaccine isn’t always one-hundred percent effective. It’s like the fall TV lineup: even with the best possible combination of what’s expected to work a few people are still going to get sick, but that’s another story. And I realize I’ve slipped from the common cold to the common flu even though they’re two entirely different beasts and could easily be distinguished at a distance if you could see them without a microscope. The common cold worries me even less because I have this completely unscientific idea that the reason I get at least one every year is because it’s always mutating and therefore one step ahead of my immune system, but this year maybe it’s gone into reruns and I’ve been able to head it off with some nasal streaming. And also at any sign of a cold I’ve started taking vitamin C even though I’ve never been superstitious, and I’m not sure why vitamin C, which is supposed to prevent the common scurvy, is always the treatment for a cold, although I think it has something to do with helping your nose thaw faster.
