Anti Bacterial Soaps don't work....

i would have to say that I agree that being too clean is a detriment. Every since I had the flu as a kid, I haven't had the flu as an adult, same way with chicken pox. Thus I feel my system has built up an immunity to all types of flu (or I just haven't been exposed to the virus..) while the people that rush out and get flu shot of the day are only really protected against that one strain since they were so clean as to not get it.
