Thanks for the summary. Some tired thoughts: #1 the premise of the book is that we (both individually and societally) are the only species intentionally depriving ourselves of sleep due to hectic lifestyle and work pressure, which cause undersleeping. It’s a factor we can change. Sleeping “too much” is associated with mortality for different reasons, which according to the book is because of deceases that cause you to be able to sleep more (which would be because the body needs more time to perform the physical recovery function for longer). Most healthy adults can't sleep longer than ~9h for an extended period of time. That, at least, makes a good argument for treating them differently. #2 Sleep deprivation therapy may work well for some people with depression, and I don’t see the conflict in being open minded. Perhaps walker is a bit too reactive in his tone? He is intentionally a little provocative, and that may indeed be harmful to people of literal-mindedness. But what’s the alternative? Putting a caveat in every paragraph that YMMV? Requiring a test that you understand aggregates and distributions in order to buy a book? #3 I remember reading the book and getting exactly that impression. If indeed FFI is a neurodegenerative prion decease (same category as mad cow decease) it’s deeply dishonest to say death is due to lack of sleep. That’s very misleading, no excuses. #4 was a misattribution to the WHO when it was in fact.. the CDC. Welp, I mean, shit happens. This definitely falls under honest mistake. #5 ok? Thanks for the correction, lol.
