Parasites and humans, Ick. High ick factor usually guarantees a good read and this book is no exception. Desowitz is a doctor who discusses some of his more interesting cases and those of his colleagues. Through the study of parasites, we can also learn a lot more about the human condition and the things that effect quality of life such as farming [some parasite laden bugs will only migrate to infesting humans when their animal hosts have left] water [more standing water = more bugs] and food prep [sushi, prepared badly, can leave you with worms]. Desowitz is a personable, even chatty writer and brings his own experiences and opinions into the mix to make an otherwise slightly gruesome topic seem really interesting and involving, even for the squeamish.
