I guess I must be doing something wrong. I get at least two colds a year. I have heard the theory that you get fewer colds as you get older because you can't catch the same cold twice, but I am sure that I have encountered all the cold germs in the world and they are always willing to pay a return visit and stay for a few weeks. I feel like the "Roach Motel" - germs check in but they don't check out. I never get the flu though. Mary Sheehan
