I have not read the book yet, but with the open discussions i have heard in recent times from the author on facebook about yourbodyyoursystem, i can say it is one book every lover of good and sound health MUST digest. It broadens one's perspective on the subject matter and makes you have a rethink about our day to day usual healthcare system, which is wide apart from what yourbodyyoursystem is all about. Dr Shiva is taking the world to a different realm in this regard.
