A British G.P. discusses 94 health facts, folk beliefs and medical misconceptions in question-and-answer format, tackling everything from ""Why does my stomach rumble in assembly?"" to ""Does chocolate cause problems like pimples or migraine?"" His one-page answers provide brief, readable explanations for medical questions asked by children and adults. There is no index, so the reader will have to browse the contents page for a listing of topics. Pencil drawings by Blake are humorous without being exaggerated. Some explanations may cause questions. Rowan states that you should not eat raw pork because of possible tapeworm infestation, but makes no mention of trichinosis, a much more serious problem. A digression into hookworms and other parasites gives the impression that such infestations are seldom serious. In another section, he suggests that your grandpa brushed his hair 100 strokes to clean it of lice and lice eggs, and suggests that brushing is an effective method of keeping them at bay, a conclusion health-care workers may dispute. But despite minor flaws, the whole is interesting reading.
