As you age, it's harder to get sleep. And that's especially true for women. They have to spend much longer time in bed than men do. So it's really important that these habits you cement. Otherwise, like you're really fighting against multiple fronts.

very quickly. And then if you miss it, you can't get it. So last week I was at a conference and everyone went out for this big party and I wanted to try to accommodate, I wanted to be with everyone. So I went to bed at 7pm. I woke up at 9pm. So I got my two hours of deep sleep and Then I went out with everybody. We had a great time. I came back home. I went to bed, I think at one or two.

And then I got my remaining six hours of REM, you know, I'll get two hours of REM, but six hours of sleep. And I still had a great night's sleep and I felt wonderful the next day. But if you wait and go to bed, like at midnight for me, I would just miss my deep sleep. It would be gone. And so like, I'm trying to functionally be adaptive to societal norms while it was still logging those metrics.

But yeah, you have to be mindful of like, if you build your life around it, then you can make these adjustments. But you really have to make a professional effort to do this because it takes like structurally, just get it right and then you'll win.

I mean, your body has a production line. So like you have a rhythm and you can get your deep sleep. So if you go to bed at 1030, your deep sleep is going to happen between 1030 and 1230. You may have a bit more deep sleep, like at two or three in the morning, but the majority is going to be front loaded. So if you miss that front window, you just miss it and you can't pick it up.

Yeah, because you have a few sleep types. You've got REM, you have deep, you have light. And deep, so many restorative processes are happening. And REM, you've got a bunch of memory reconciliation and whatnot. But deep, you just have this restorative building process. So you basically miss out on all those restorative processes if you miss it, which is why the brain hurts when you don't get it.
