Conserve, Reuse, Recycle: by a guy named Waldemar

1. The exact sentence that reveals Semrau's point is "Quite simply, use what you have until it can no longer function. Then it's time to recycle."

2. Semrau probably kept information from his readers because he wanted to keep them in suspense. By talking about himself being 75 years old and just now deciding to "attend" Harvard Medical School, on the surface, that doesn't seem logical. He then goes on to explain the registration documents, and by this point it appears that he's gone crazy, along with the Med-School dean who would dare accept a senior citizen to study the ways of surgery. But then, his intention is finally revealed in the next paragraph, where he says that he had previously read a book by Mary Roach, titled "Stiff: the Curious Lives of Human Cadavers", and it is evident that Semrau is planning to be a "human cadaver, an anatomical gift" to Harvard. Then it is clear that he is planning to donate his body as part of the reusing process, so the students at Harvard can reuse Semrau's body in a different way, in order to study anatomy.
