After several years without a noticeable cold, I’ve caught a distinct one, complete with lethargy, lack of energy, sore throat, sinus headaches, and runny nose. I am doing the folks at work a favour by not going out and spreading it. It seems to be the same infection that LotStreetWiz had last week.
Coincidentally or not, it has also been several years of getting a flu shot. However, I suspect that one simply gets fewer or less severe colds through the years through developing immunity to the commoner types of viral protein coats.
