So I think the first thing is ask yourself some honest questions. Am I getting enough sleep? The next question then is to say, even if the quantity of sleep I'm getting is sufficient, maybe I still do not feel restored or refreshed by my sleep the next day. And that comes on to quality over quantity. It's not just about how much sleep you're getting.

It's about how well that sleep restores you the next day. In fact, that's one of our new metrics of insomnia. You can fall asleep fine. You can stay asleep. But if you don't feel restored or refreshed by your sleep the next day, you can still receive a diagnosis of unrestorative sleep leading to insomnia. Insomnia is much more a waking day disorder than it is a sleeping night disorder.

What do you mean? Because you feel bad during the day? Because you feel bad during the day. And so we've now tried to upgrade or at least refine the complexity that is insomnia to represent the patient themselves and their true experience. So understanding that your quantity and quality are good or bad then leads to the next set of questions, which is, well, what do I do about it?

Now, take what I say with a grain of salt. I'm wearing two Oura rings right now. I know, yeah, one is sort of a next gen, and the reason why is that I'm a scientific advisor to the company. So take anything I say with a grain of salt, absolutely. So complete, and they look very much similar. So complete disclosure, and that's important.

I would say, though, that for most people, tracking your sleep can be a very worthwhile thing. And it's simply because sleep in part is a non-conscious process. I can ask you, you know, Mark, in the past week, have you been eating well or not eating well? And you can tell me, have you been exercising consistently or not? Yes, you can.

But if I then said to you, how much deep sleep did you get last Tuesday night?

I have no idea. No one has any idea unless you have the historical record of your sleep. So I think it can be very helpful. Are they accurate? You know, I only know about aura and I think it's, it's probably, I know the algorithm, um, and I've helped with that algorithm. You know, it's going to be about close to 80, maybe more percent accurate at determining wake from sleep.

You know, it's going to be about close to 80, maybe more percent accurate at determining wake from sleep.

And then when you split it four ways, light non-REM, deep non-REM, REM sleep or wakefulness, which are really the four states that you can be in, which is a four class algorithm. then the accuracy is about maybe 75%. And that seems to be about best in class right now. Now you may say, well, hang on a second, that doesn't sound so impressive, 75%. Think about this though.
