This is an important book. We need a bigger population of non-fiction readers for writing reviews.
Let's start.
First chapter is already on what happen when we sleep.
So, the first part of when to sleep and what is the best time to wake up is already known.
The second part is on larks and owl chronotypes. Questions that one answer would determine if a person is morning person or night person with different peak period of performance.
200 pages in.
This is good. The part about how Freud get it all wrong in term of dreams related to sex.
The dream is a mild de-stress for some, but might caused more stress for the very depressed.
Some writers do use dreams to make plot, including Stephen King. That's part is good.
One more chapter.
Knowing that children benefit from bed time reading is great. And all the more reason to encourage this habit.
Done.
It is a bit light. Not that academic as one would think, but interesting never the less.
The thing is, the book read like a self help book without woo. That would be good for the mass market.
So, four and a half stars. Not perfect. Not great. Like a good pancake with maple syrup.
