This book was amazingly helpful to me in making sense of chronic illness and seeing a bigger picture than what we typically learn in books about various illnesses. Some parts are a bit complex, but Ewald does a nice job of making the topic as understandable as possible. I was absolutely blown away by some of the historical points (such as findings in the 1800s about bacterial connections for major, common, chronic diseases). Ewald does say a few things that may prove to not be true (most significantly, that Lyme cannot be passed on from humans), but overall this book is incredibly enlightening. I would highly recommend this book for EVERYONE.
