Also a big Sapolsky fan, but I did really like this book. That said though, I have only a read-a-lot-of-books-from-people-like-sapolsky level of knowledge on the subject, so take my opinion with a large grain of salt.
If you can remember, I'd love to know what some of the issues were with the book!
