I never got sick back in the midwest and I've gotten 3 colds here that didn't act like colds or what I considered as a "cold". I'd get a cold back in missouri and I was still able to function, here I'm bed ridden for a few days. The colds are almost flu like, maybe its the flu. I dunno. I never got the flu back home either. I was sick the entire month of October this year, I couldn't believe it.
