JUST IN CASE anyone is expecting to read about new markets for Wur|itzers, let me set you straight. I mean to discuss organ transplantation and, especially, what to think about recent proposals to meet the need for transplantable human organs by permitting or even encouraging their sale and purchase. If the reader will pardon the impropriety, I will not beat around the bush: the subject is human flesh, the goal is the saving of life, the question is, "To market or not to market?"
