Query: It is not that simple.

As a textbook of physical exam, this book really needs more and more and more drawings if the author does not have appropriate pictures or the publisher does not want to spend more money to print them. Descriptions are oversimplified, too. Do not rely too much on nonspecific or insensitive physical findings, it would be quite dangerous.It is hard to read.I bought this because my Bates is almost 20 years old. I decided try another one from Mosby.If I still live in the USA, I would sell this.
