How much do I want to read more? 7/10

I was a bit biased about this book. Articles on the web state how wrong are the data and the studies from this book. Some say this book is doing more harm than good. Everything has to be taken with a grain of salt.
Bill Gates said it's a fascinating read nonetheless.
After a few pages read, it's indeed captiving. The naive view of sleep is a waste of time 1/3 of our life would be waste in a "black hole" we don't know anything about?
When in high-school I was so obsessed with getting good grades, I would purposefuly zone out until 4 am like a zombie, staring at my notes, doing nothing else but inflicting self-damage. The side-effect was, I sinked deeper and reached my scariest fear, to fail at school.

Part 1 - This Thing Called Sleep

CHAPTER 1 - To Sleep…

“I’ll sleep when I’m dead”. Adopt this mind-set, and you will be dead sooner.

human beings are in fact the only species that will deliberately deprive themselves of sleep.

Minds of the most stringent kind, including Nobel Prize–winner Francis Crick, who deduced the twisted-ladder structure of DNA, famed Roman educator and rhetorician Quintilian, and even Sigmund Freud had all tried their hand at deciphering sleep’s enigmatic code, all in vain.

Consider that we have known the functions of the three other basic drives in life—to eat, to drink, and to reproduce—for many tens if not hundreds of years now. Yet the fourth main biological drive, common across the entire animal kingdom—the drive to sleep—has continued to elude science for millennia.

When you are asleep, you cannot gather food. You cannot socialize. You cannot find a mate and reproduce. You cannot nurture or protect your offspring. Worse still, sleep leaves you vulnerable to predation. Sleep is surely one of the most puzzling of all human behaviors.

“If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made.”

Yet sleep has persisted. Heroically so. every species studied to date sleeps.

the subsequent perseverance of sleep throughout evolution means there must be tremendous benefits that far outweigh all of the obvious hazards and detriments.

We sleep for a rich litany of functions, plural—an abundant constellation of nighttime benefits that service both our brains and our bodies. There does not seem to be one major organ within the body, or process within the brain, that isn’t optimally enhanced by sleep.

Within the brain, sleep enriches a diversity of functions, including our ability to learn, memorize, and make logical decisions and choices.

It is difficult to imagine any other state—natural or medically manipulated—that affords a more powerful redressing of physical and mental health at every level of analysis.
