Wow! If this is true I've got it made. Sometimes it feels like I'm up to my knees in poop.
In all seriousness. My kids do have particlarly well developed immune systems. I don't keep a very clean house. I don't use bleach if I can avoid it. I let my kids play outside - even (gasp) get dirty. I've often wondered if the fact that they're exposed to so many germs might have something to do with that, this article goes right along with that thought trail. I'll be interested to see what developments the study finds.
