Why We Sleep: Unlocking the Power of Sleep and Dreams by Matthew Walker

4.0

It's 9:43 and I really need to start getting ready for bed soon. And make sure the bedroom is cool, dark, soundless, no alcohol or caffeine in my system, otherwise . . . I'm doomed to suffer obesity, Alzheimer's disease, high blood pressure, stroke, cancer, high cholesterol, and heart disease.

I'll probably have trouble sleeping just thinking about all the bad things that will happen if I don't get enough sleep.
