Melvin Konner, a renowned doctor and anthropologist, takes the measure of the “Jewish body,” considering sex, circumcision, menstruation, and even those most elusive and controversial of microscopic markers–Jewish genes. But this is not only a book that examines the human body through the prism of Jewish culture. Konner looks as well at the views of Jewish physiology held by non-Jews, and the way those views seeped into Jewish thought. He describes in detail the origins of the first nose job, and he writes about the Nazi ideology that categorized Jews as a public health menace on par with rats or germs.
