'Ya know, at the risk of being thought totally disgusting, especially with my nose-picking thread going, I agree with WW. I don't think it's healthy for us to try to sterilize our world like we do. I refuse to buy antibacterial hand-soap. Bacteria isn't all bad, and if we avoid all exposure to the disease-causing varieties, our immune systems won't know what to do when they do run across it. All the auto-immune and immune system insufficiency type diseases that people have now used to be much rarer than they are. Lack of exposure to natural stuff and over-exposure to chemicals and artificial substances has to be to blame for a lot of it. We weren't meant to live in a sterile world.

Just a thought.
