Oh my god, I love Mary Roach. This is my first book written by her and despite it's rather ghastly contents, it was absolutely wonderful. Very well written, with a nicely humorous tone without ever getting derogatory or cheap.
I liked the journey from what to do with a willed corpse to where to alternatively lay it to rest, if donating your remains isn't for you. And I never knew there was this much left to do for a dead body.
