The amazing thing about transplantation, aside from the fact that it worked, was that it allowed people to feel again. The thing I liked best about my previous life was the first smile when a patient woke up. Because with that smile, I knew that I hadn't simply given that persona new pump, I had given him or her a new pump that allowed that person to live, to express emotion. It was the smile, even more than the first beat of the heart, that told me it had worked.
