As I read this book I kept thinking about all the people I knew who would benefit from it: family and friends whom I want to have healthy happy lives, managers who believe that they'll get more out of people by pushing them to work crazy hours… and lots of people who think they’ll get more out of themselves if they sleep less.

I second parent's comment that for me this was one of those perspective-altering books in recent years. Even now, months after I finished, I still have several thoughts going through my head: why schools start so early, the societal impact of sleep deprivation, why doctors complete ignore the importance of sleep for your health [5], what happens when you drink alcohol (particularly at night), how Alzheimer's works, lucid dreams, and more.

Why we sleep. This book motivated me to change my sleep habits after decades of being a night owl. I’m starting to love early mornings, and I feel so much better. This was a hard change.

After reading about it, I've learned a lot more about sleep, but the greatest effect is that I really appreciate sleep more, make lots of time to optimize length and quality. Knowing all the info in the book it would be difficult to justify using an alarm clock to force yourself to rise before your body is ready.

Why We Sleep by Matthew Walker... I used to be a chronic advocate for sleeping less until I read this and did my own scrappy post-research. I'm much more conscious of my health and my sleep now.
