One of the original printings of this book not the expanded version that came out later. I slowly read it week after week at a lending library at my docs office, until I just figured I should take it home and read it all... so I did, ive read it before, but given my doctors chronic lateness it was good to have something to read while I waited for him... showing up 15 mins early I would regularly wait close to and hour and 45 mins... he was that late. Boy a book makes up for such problems.
