All this cootie talk made me snort coffee. Very amusing. And here's my two cents worth: I ate a lot of dirt as a kid, enough so even now I can look at the ground and imagine what it'd taste/feel like. I have no idea why I did this, but I have numerous chronic health problems/digestive/allergy/asthma/nerve/immune... Guess I was one that'd been weeded out along the way.
Nope, don't wash eggs unless I'm going to crack open a dirty one. My favorite is soft boiled anyway, so I figure that'll clean it up. Clean ones are the majority anyway, and if DH would stop giving them away I'd have enough around here for eggsalad, deviled eggs, and all.
Cooties are much more a hazard out there in stores or the doc's office. And that's a terribly funny illustrative about the finger. Another coffee snorting.
