The Transplant Problem

You are a doctor. You have five patients in dire need of various transplants; two need one lung each, two need a kidney each, and the fifth needs a heart. If they do not get these organs today, they will die. A young man with the right blood-type and in excellent health has just entered the clinic. You ask him if he is willing to be a donor, and he says that while he is sympathetic, he is unwilling to donate at the cost of his life.
