Sleep is a critical life support system protecting against nearly every major disease in the developed world.

“it is the greatest life support system that you could ever wish for it is a remarkable health insurance policy and what's great is that it's largely democratic it's mostly free and in terms of a prescription from a doctor it's largely painless so i almost wanted to title the book consciousness is overrated or just sometimes dot dot consciousness is overrated but when you really look at the evidence in terms of risk de-risking just about every disease that is killing us in the developed world it's very hard to look no further than sleep”
