Query: Learned a bit, that's all I ask.

Several reviewers commented on author Mary Roach's humor, either for or against. I am neutral.The information was sometime distressing, especially in her chapter about the decompostion of cadavers. I had wanted to donate my body to science, but maybe not that kind of science. (Seems kind of lonely, even for something dead.)STIFF is a worthwhile read. Try it, you'll learn something.
