Organ Donors

K and I were out to dinner and chatting about being organ donors (for some reason).  She's against it.  (Don't ask.  She has her reasons.)  I'm for it.  I mean, why not?  I'm dead.  What possible use do I have for my organs?

She conceded her eyes.  Literally.  "I guess I'd donate my eyes," she said, finally.

"So wait," I said, thinking it through, "You're O-Negative, right?  That's the universal donor, isn't it?"

"Yeah."

This will prove how much/little I know about organ donors.  Is it all down to blood type?  Or are there other methods of determining compatibility?  I have no clue.  Bear with me, here.

"So if you and I were in an accident, together, I mean a bad one, and you were killed instantly but I was left alive, barely alive, and let's say all I needed was a kidney, you wouldn't be able to give me one of yours because you're not a registered organ donor."

To give her credit, she considered that for about a second before she said, "You'd want to live without me?"

Touché.
