ESCANABA Imagine not being able to breathe. Thats how life was for Bill Weissert, of Escanaba, and Dan Simpson, of Arizona. Chronic lung disease required both to undergo lung transplants at the University of Wisconsin and veterans hospital in Madison two years ago. Each received a lung from the same donor. Lungs are the hardest organs to transplant, said Weissert. They have the least success. Ironically, doctors claim that lung transplant recipients develop closer bonds than other organ recipients, he said.
