Why would an arguably normal, healthy individual submit himself to hundreds of blood tests, body scans, brain scans, and other medical tests? Have his DNA, and his family's, analyzed for genetic diseases, as well as for genes that affect personality, intelligence, physical and mental abilities, and more--then publish the results for all to see? Journalist David Ewing Duncan's mission, as perhaps the most tested healthy person in history, is to discover what cutting-edge medical technology can tell him, and us, about our future health; the effects of living in a toxin-soaked world; and how genes, proteins, personal behavior, and an often-hostile environment interact within our bodies. These tests and more will soon be available to millions--but will knowing the intricate details put our minds at ease or make us paranoid? Will this information be used against us? Duncan explores these and many other questions about the nature of life in the twenty-first century.--From publisher description.
