Clip the dog in with my right hand. I'm closing the drawer with my left. Open the front door with the left. I go down the stairs. I look across. There's that weird Berkeley house. It's kind of just a little bit hippie, but no problem. And then the cars always come too quickly around that bend. That's the level of hyper detail.

And what's interesting, if you look across all four of the things I've just described, the commonality is that they all get your mind off itself. Meditation, you're starting to focus on something other than your mind. If you're doing box breathing, you're all of a sudden body centric, not mind centric.

If you're starting to do some type of body scan, again, it's hard for you to think about your worries and your stresses if you're doing it. Mental walk, same thing. Because sleep at that time of night is a little bit like trying to remember someone's name. The harder you try, the further you push it away. Sleep is something that happens to us. It's not something that we make happen.

And when you get that mind focused, distracted away from itself, the next thing you typically remember is the alarm going off in the morning. Why? Because you got your mind off itself.

Okay. So first one, quantity. Second one, quality, that being a component of that. Is there anything else to say on quality before we move on?

Yeah, probably. The other way that we measure, and most people can't do this, but is in the sleep laboratory, we place electrodes on your head. You And the other way we measure quality is the depth of your deep non-REM sleep. So we have two main types of sleep, REM and non-REM. Non-REM, for most sleep trackers, you divide it into light non-REM and deep non-REM.

Deep non-REM is where you get these incredible, deep, powerful, slow brainwaves that are just epic.

Deep non-REM is where you get these incredible, deep, powerful, slow brainwaves that are just epic.

And the depth, the size of those brainwaves and how dense they are, the number of them that you're having is another great measure of the quality, the electrophysiological quality of your sleep versus the, are you waking up lots throughout the night and therefore you're spending a lot of time awake, that sleep efficiency, that's another measure of quality.
