The author continues to cover the same ground on how good Tai Chi is for one medically. After about the 10th time it becomes over kill. I haven't finished the book as I'm turned off by the lack of information that is true information on how to practice Tai Chi, look for a teacher, etc. As I have now found a true Tai Chi teacher, I realize how poor this book really is. This is the authors own style and does not necessarily reflect the main Tai Chi styles taught. If you're looking for a book on "real" Tai Chi, this isn't it.
