Because of my chosen profession, I have to be pretty tolerant of many things that most people think are disgusting.  Blood, body parts, organs, and with my chosen specialty, even pee.  I can handle them just fine.  In fact, there is nothing I find more fascinating than having my hands down inside a human body, working on making it better.

That really gets my motor running.

You would think that, having become immune to being grossed out by that sort of thing, that I would be pretty immune to most things.  But not all.  I have an Achilles heel.

Poop.

Yes, poop.  There is just something about it that makes me sick.  That doesn't mean I don't have to deal with it.  I change plenty of diapers, and have even had to hand-scoop the occasional log out of the bathtub.  I can do it.

But I hate it.  So, so bad.  My jaw starts to tingle, I taste something bitter in the back of my throat, I start to feel a little light-headed.  Not every time, but it is the one thing that really, really gets to me.  I can eat lunch while watching an operation.  I can talk about the surgery I did over dinner.  My wife yells when I do, but it doesn't even daze me.

But those dirty diapers.  They really get to me sometimes.
