Doughty went into the death biz to heal herself from a childhood trauma triggered by witnessing a little girl's death. But she finds the whole thing so fascinating that she wants to open it up for everyone. The book is written with delightful humor and an anthropologist/historian's research. You learn everything from the practical "how to" of cremation, to the history of death and body disposal, to rituals of different cultures and death mythology, to the secrets of the embalming industry. Doughty offers a curious reader "The realistic interaction with death and the chance to face our own mortality." (114) This is a very easy book to read—for me, a welcome education from an expert teacher. It was fun, fascinating, exhilarating, as freeing as the aforementioned Buddhist exercise, and validating of my personal decision to avoid the funeral industry and all expensive death rituals.
Years ago I wrote a feature about free (as in no cost) body disposal by using what's left for altruistic purposes: Why I'm Leaving My Body to Science. The article lists resources, in case you're interested in doing the same thing.
