Getting Sick

I'm just getting over a rather bad cold, but I realized that since I've got back to England, I've been getting sick with a much higher frequency than I ever have before. Back in Florida, I used to get sick maybe once a year, around the time everyone goes back to school. But here it seems to be every couple of months. I could understand if it happened when I first got back, as maybe I wasn't "used" to the germs over here. That happened the first week I lived in New York. True story.
