It's not a hobby.
It's not something you do for fun.
People don't just go "Oh, I'll have a new organ, that sounds fun" or "Know what, I think I'll give away my insides today."
You recieve them when you're terminally ill. You recieve organs to make you better.
You give them away if you die, not before.
I don't think you fully understand the purpose of Organ Donation, or being on an Organ Donor Registry.
I don't think you're understanding any of what I'm saying at all.
When I said "that sounds like a forgeted up hobby" I was joking, I guess I misinterpreted the tone of what you were saying, when you said:
And why would you want to recieve them? Signing up to be a donor isn't like promising to clear out your insides and lend the pieces around.
You don't just recieve organs.
Let me put this into a different perspective:
Someone loves participating in xmas, because they love receiving gifts
They never give anything during xmas though, because they don't want to
^^^Sounds like a selfish ass-hat right?
If I'm not going to give anything, I shouldn't be receiving anything in return.
Let's say hypothetically that I end up in a horrific accident and I need a transplant, otherwise I would die. Before this accident I had come to a discovery that "body part mixing" is perfectly fine, as well.
Now lets say that there is an organ that was donated previously: which is suitable for transplant to my body, a good match. However this same organ would only match to my body, nobody else on the registry could receive it but me, not a single person.
If I had no beliefs against mixing body parts with strangers, then I would accept it; otherwise it would be a waste of a perfectly good organ and it would just sit in a jar somewhere for the rest of eternity, right?
If I had no beliefs against mixing body parts with strangers, I would be donating my organs after death as well; but I do have those beliefs so it's not happening unless if as before: I make some discovery that works in favor of donating/receiving.
I hope this clears it all up.
