No one would look at an infant baby asleep, and say 'What a lazy baby!' We know sleeping is non-negotiable for a baby. But that notion is quickly abandoned.

If we didn't need eight hours of sleep and could survive on six, Mother Nature would have done away with 25 percent of our sleep time millions of years ago. Because when you think about it, sleep is an idiotic thing to do.
Interpretation
What this quote means
The quote suggests that sleep is an essential biological need that has evolved over time, and it highlights the puzzling nature of sleep.
Matthew Walker's quote draws attention to the evolutionary importance of sleep, emphasizing that if humans could function well on less sleep, nature would have eliminated the need for the hours we spend sleeping. It underlines the paradoxical notion that while sleep may seem wasteful, it serves crucial functions for our overall health, performance, and survival.

Sleep is the Swiss army knife of health. When sleep is deficient, there is sickness and disease. And when sleep is abundant, there is vitality and health.

Regularity is a key: going to bed at the same time, waking up at the same time no matter what. But I think, also, it's not just about quantity - that's what we've been discovering. It's also about quality.

You're trying to sleep off a debt that you've lumbered your brain and body with during the week, and wouldn't it be lovely if sleep worked like that? Sadly, it doesn't. Sleep is not like the bank, so you can't accumulate a debt and then try and pay it off at a later point in time.

As you try to tweak your sleep one way or the other, you might be, you might be doing great - you might do better at remembering details of an event, but you might end up being poorer at abstracting the gist or the rules associated with it.

In any finite region of space, matter can only arrange itself in a finite number of configurations, just as a deck of cards can be arranged in only finitely many different orders. If you shuffle the deck infinitely many times, the card orderings must necessarily repeat.

But it will be found... that one universal law prevails in all these phenomena. Where two portions of the same light arrive in the eye by different routes, either exactly or very nearly in the same direction, the appearance or disappearance of various colours is determined by the greater or less difference in the lengths of the paths.

'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes its multitude of changes, this number doesn't change. That is, if you calculate again, this quantity, it'll be the same as it was before. An example is the conservation of energy: there's a quantity that you can calculate according to a certain rule, and it comes out the same answer after, no matter what happens, happens.
