Sorry I want a Viking Funeral and everything, organs and all get to go up in smoke with my corpse. That or bury me in a Cairn. But in the end I want all my organs inside me when I do. Do I have a reason to want this? Sure, There mine and you can't have them. Thats all the reason I need.
Well, I've got a solution for that!
We'll just add a clause that you can deny the hospital the use of your body after you're dead. You just have to sign a simple form in person. After the decision's been made. ^-^
Slightly more serious;
Amalor's argument is basically the same as mine, with one important difference: IMHO your body isn't yours
or the hospital's when your dead - it's part of your next of kin's inheritance, so they should be the ones to decide what to do with it.
The problem is, when you think about it, how rational are people right after a close relative's died? And how well do multiple relatives agree? The best thing (and I don't know if it would be workable either) IMHO would be to have an opt-out system where your closest kin (family, your parents, maybe a few more) can say no. Then you can try to convince
them about how you want it, but they're after all the ones who'll be in some way affected by the decision so it stands to reason they should get to chose, no?
