Transplants don't really work, they are experimental. I am already a donor. I have it on my driver's license. Doctors may let me die so they can transplant organs to their other patients.
Every effort is made to save a life before donation can be considered.
Wealthy people can buy a transplant. There is no way to buy a place on the waiting list. I am too old. You don't want anything I have. Every person is evaluated at his or her time of death for potential donation.
