Germs good?

So today on I think it was Good Morning America, they were talking about how because of people being such germ phobes and always using antibacterial soap and disinfecting everything, people are starting to develop auto immune diseases and have more allergies, because our bodies aren't being exposed to enough germs, so that they can build up their defenses.( yeah, I realize that was a run on sentence, lol) They believe it's that combined with all of the chemicals in the air, in the produce and in our meat. ( Non-organic food) Kind of scary that we're weakening ourselves unknowingly. So I guess what I'm really saying here is that maybe my non-emaculate house keeping may actually be good for my family? LOL
