Good article. There's way too many germaphobes nowadays in my opinion. And all these hand cleaner/sanitizer things can't be good for the general health of all. Again, just my opinion. Our immune systems are designed to fight off these things so that we survive. If we're never exposed to them, it only makes things worse in the long run.

Does it work for adults too? Because I just asked my husband if it was dirt or a bruise on my leg after cleaning our filthy car...and he licked it. It was dirt. Immune system boost right?
