That's interesting, but when reading the book my takeaways weren't really whether some cancer risks doubles or so.
They were
* what are REM/NREM, light and deep NREM sleep for?
* some fascinating study about lucid dreaming
* effects of coffein and sleep medication
* sleep hygiene tips
* some other things I can't recall right now
Yes, you can read about these things elsewhere, too, but I still think the book is a tremendous introduction to the subject.
But I don't have an academic interest in the subject, so the criticisms in the article do not matter much to me (except for some uneasy feeling about accuracy in general). If you're a student of medicine, cognitive sciences or whatever, you should probably get your introduction elsewhere anyway.
