Rush and Me . I used to be a good friend to Rush. I listened to his program all the time. When I first saw this book, I ignored it. Finally, after it had been in the window of our bookstore for several months, I picked it up and looked inside.    I was amazed!     However, I had to put it down because I thought it was too negative. It called Rush names. I did not need to have that. Finally, I tried getting it at the library, but they said they did not have a copy, because they said it was "too controversial."    So when the price came down, I bought a used copy for a couple of bucks, and read the whole thing.    I was amazed some more!    Rush used to have 20 million listeners to his talk show. He was a legendary, rich talk show host. This book tells you exactly how Rush became a rich, popular talk show host. And he is thinner now that he has recovered from his unfortunate drug problem. And you know, that sort of thing could happen to anybody.    But I had trusted Rush, and his VALUES, and I kind of felt he let me down. So for me, the title is not appropriate. Rush Limbaugh is a Big, Rich Talk Show Host who Cuts Corners on His Values would be a better title. Rush is no idiot, either.    Now, by some "coincidence" Al Franken is a talk show host too. And, I bet he learned how by studying how Rush did it!    If Franken can do it, YOU can do it!    Don't miss out on this GREAT opportunity!    Get a copy. Look how cheap it is now. Tell your friends

One of the best books on tai chi . This book presents the 24 and 48 posture tai chi form. The 24 move form is good for busy people, but the 48 move form is even better because it combines movements from the 3 most popular styles of tai chi, Yang,  Wu, and Chen, so the student gets some background in each. At 150 pages long in large paperback format, this book packs a lot of info between the covers. For example, I learned that in addition to the Wu style, there is also a W'u style, which I didn't know, although I've studied both Yang and Wu style tai chi.     The author gives a brief introduction to tai chi in the first chapter, discussing basic concepts and information, then proceeds to some classical Taoist philosophy. He also tells some interesting stories about the founder and his sons, who had many adventures and exploits, and various stories and legends have grown up around them.     Next there is a separate chapter on chi gung, a subject that has become almost a requirement for a tai chi book, I notice. However, most of the book is taken up by athe chapter showing the martial applications and the 48 move form. Dozens of applications are shown, and the photos are clear and easy to understand. I found this the most enjoyable part of the book, as there are still postures I don't know all applications for, such as snake creeps down, and the author presented one on that.     There is a chapter on guidelines for tai chi practice that gives detailed instructions for how to use the different parts of the body, from the eyes to the feet in performing the form. I found this useful because sometimes I still forget some of the fine details of how to hold the body when I do the form.     Finally, there are several appendices which provide a list of the 24 and 48 postures and their translations, a glossary on Chinese terms that is more complete than most, and a brief bibliography for further reading. The book is well written and easy to understand even when discussing some of the more abstract and esoteric principles. There are two mini-biographies of each other, two prefaces by two different masters, and a preface by the notable Dr. Yang Jwing Ming
