"Psychologist Shelley E. Taylor didn't know there were any big mistakes left in science, until she learned that the classic theories of stress - most notibly the "fight or flight" response - were based almost entirely on studies that involved only male subjects. In setting out to discover how women respond to stress, Taylor and her colleagues revealed a profound truth that revolutionizes our understanding of human behavior: we are biologically programmed to care for one another."--BOOK JACKET
