The whole issue would be resolved if, in order to receive a donated organ, adults would have to already be registered as donors (prior to the diagnosis).
"In order to get, you have to be willing to give" is a simple protocol and would easily resolve the issues surrounding organ transplants.
That seems reasonable to me.
However, after having worked for 25 years in the medical field...the first time someone came up who needed an organ who was not a donor...it just wouldn't apply. I can see the sob story headline now: "Medical Center refuses lifesaving procedure to the father of family..."
Excellent idea! It would be fair to the supporters and opponents of organ transplants.
