Miscellany: Down with the sickness

I suppose it's reassuring that some things never change, and the one thing that's constant about the common cold is that it's always mutating. Caused by a variety of different viruses, the common cold is nature's version of a stress test for the human immune system. From the moment you are infected, you body mobilizes forces that will eventually destroy the viruses, but not before you feel miserable for a few days.

I've got a runny nose and a sore throat. Thankfully, my immune system is ready to rumble.
