Query: A Book for the Boomer Generation!

How nice to finally read a medical book not cloaked in jargon that needs a university degree to comprehend. Authors O'Connor and Perkins have taken the topic of osteoporosis and written a book - in normal English -that explains it in terms everyone can understand. From the causes and symptoms to the foods and exercises that help control osteoporosis, this is THE book that anyone who suffers from it, or knows someone who suffers from it, should read!
