You know what I do when I come across some weird slimy thing lying on the ground. I leave it alone and keep walking. Not a kid. They have to inspect it. Pick it up. Play with it. It doesn't matter if it's a living thing a dead thing or something indeterminate. A kid has to touch it. That alone would be fine, but here's the really good part. Kids don't wash their hands!
OK, I can tell I haven't convinced you. So here's another reason not to have kids>>
