People have festered a general level of hostility in my psyche that is only overcome by personal attachment.
I'd be willing to give my organs to someone I cared about, but not to just anyone who needs them.
I actually plan on being subjected to sky burial (i.e. fed to vultures) after I die, so that someone can get some use out of my corpse. I am more comfortable being generous to vultures I don't know than people I don't know.
If I had a guarantee that nobody else would profit due to my donations (insurance, doctors, hospitals), then I'd donate. If everybody else donates in conjunction with my donation, then the system would be worth buying into. Until then, I will not be party to the broken US health care system.
Just thinking about the question with my nit-picking-bastard hat on, technically you're not actually a donor until you donate something. Until that point you're a potential donor, or an intended donor, or somesuch.
From that point of view I am a potential donor.
In Spain, everybody is an Organ Donor. If you want to keep them, them you should sign up in the non organ donors list.
It's on my DL. You're all (all 6B of you) welcome to all my parts, once I'm done with them.
