I'd be happy to donate my organs, after I'm dead. But not a moment sooner. When end-of-life care is altered to prepare organs for transplant, ownership of those organs already been transferred, away from the rightful owner who is still using them.
Living Wills give medical facilities room to make mistakes and then not be held accountable for them.
And then they want the organs for big dollars. Remember the movie Coma? Tom Selleck was suspended in mid-air. I think he was killed in that murder for his organs. That was a while ago.
