At a time when we are all gravely concerned about the cost of health care, medical technology, paradoxically, is expanding and evolving as never before. Experts agree that we are entering a Golden Age when many clinical treatments that today seem like science fiction will one day become part of a routine trip to the doctor. University of Pennsylvania Medical School Professor William Hanson offers intimate true-life stories that revise our understanding of mortality. From brainwave-operated wheelchairs, to electronic noses that diagnose disease, to surgery by remote-controlled robots and nanoscale machines that will identify and kill individual malignant cells, this is a startling and exciting account of innovations that will directly affect our health.
