Sick Again

I heard on TV just recently that there are 106 cold viruses. Once you've had one, you're immune to it from that point on. So every time you catch a cold you can subtract one from that list of 106. It sure seems like I've had that many colds in my life, but I guess if I think about it rationally, there's no way. I'm 55 years old. I'd have to have had nearly two colds each year of my life to exhaust the list. And when you think about it that way, you see that it's almost impossible to have 106 different colds in a lifetime. I know there were years when I caught a couple of colds. There were many years when I didn't catch any colds. So I'm going to estimate that I've now suffered through - maybe - 25 of the 106 cold viruses. That leaves 81 left for me to catch, if exposed.
