If you, or anyone you know, has cancer, heart problems, rheumatoid arthritis, gastrointestinal problems, migraines, or other common afflictions, this book can prevent a lot of pain and suffering, or even save your life.
If you mearly have an interest in health issues, you should read this book.
This is NOT a self-help book. What it is, is a compilation and commentary on research into the psychosomatic and characterological components of illness, written in lay terms. It also offers findings on studies regarding psychological therapies for these problems, with clues to areas to address in self work.
For a technical medical book, I found it immensely readable and very insightful.
