This book is almost as annoying as it is astounding. Robert Becker is an orthopedic surgeon who spent most of his career studying bone-healing, tissue regeneration and the biological role of electromagnetic currents and fields. He wanted to find out how and why some animals could regenerate entire limbs and even vital organs and hoped that some of this resilience could be unlocked in the human body. Early on, he read reports from the Soviet Union about “currents of injury” —weak electrical flows in plants and animals that seemed to have something to do with tissue repair. In the West, bioelectricity was regarded as a subject unfit for serious research . . . .
