There's really nothing that can be said about the content of this book that hasn't already been said, analyzed, etc. I didn't particularly enjoy reading it until it got to the biology--genetics, cell structure changes, cancer. Before that it just seemed all muddled. Obviously all these things are known now so there were no revelations, but it was interesting to see what wasn't known during that time.
