excellent reference . Like other reviewers, I agree that a book is no substitute for instruction by a teacher.  Nevertheless, this comes as close (for the Yang style short form) as anything I've found.  Even if you have no interest in the martial aspects of taiji, having the potential applications of the form enriches practice.  I found the illustrations clear.  I own a half dozen or so books on taiji, and this is the only one I regularly consult

Good Grief . Like many reveiwers have already stated, this is a different type of King novel. There definitely is a slow unwind at the start for the first hundred and fifity pages or so, but I personally found much of it engaging. Beyond the main love story and Lisey's coping with grief over the loss of her writer husband, much of the book deals with Scott's damaged childhood, and the outlets the creative mind take to cope and fabricate in order to survive, but also in his case, to thrive.  The climax for me was a slight disappointment, however the book overall was a reinvigorated and different world for King

A great program!! . I know DR. Young and Shelley personally. They went to school with my dad and are great people. I have been to their home and retreat center Rancho Del Sol, and it is a great place. I also have been on the Ph Miracle diet for about 6 months now, and it works! I have lost over 20 pounds since then and I have cleared up some nasty protein pools in my blood that Rob found six months ago when I started the program.  At first I was a bit skeptical and hesitant to go on the program, but after time I felt that it was working and it was great. The food - which is cooked by a good friend of my family's and is also on the Ph program - is excellent, and the program is great.  And, those jerks that attack Rob and Shelley personally are nothing but low-life jerks. Rob and Shelley are wonderful people and great friends of mine. On their retreat to Rancho Del Sol, they went so far out of their way to help me and all of the others on the retreat.  And, when you watch Rob do a live blood test, it is fascinating. He presents his findings in conferences that are followed by a great Alkaline lunch. And the findings are very interesting. He bases most of his work on the work of A. Bechamp, an 18th century scientist that was an understudy of Louis Pasture. The facts are there, and quiet fascinating. He (Rob) is brilliant, but a bit excentric. But that is understandable considering his passion for his work.  Over all, this program works. I love the alternative path way to health, but do admit that Western methods are needed at times. I just feel that you don't need to "Dope up" on Px drugs at the first sigh of trouble.  So I give this 5 stars not just for the program, but for Rob and Shelley as my good friends.   But...  Do this in moderation to other healthy lifestyles. Don't just go 100 percent Alkaline all of the sudden. Slowly work your way to that wanted PH and be moderate with other health practices.  So 5 stars for me.  The book presents it all. A great read on the Ph program for weight loss! But do not assume something until you have read the book. And forget what you might think about the program until you read the book and have a sound understanding of Rob's theory.  Thank you Rob and Shelley!!
