Even after reading the article, I still believe, in general, more sleep is better for you. I'll continue to strive for 8 hours a night. I would still assume the majority of Americans aren't getting enough sleep.

Maybe this does help the feelings of "If I don't get enough sleep I am going to die young" that some may come away with after reading the book. Overall, I'd still recommend the book.

Also, who is "Big Sleep" that is mentioned at the end of the article? Mattress companies?
