Yeah.

Well, it's really interesting because this whole idea of your circadian rhythm and that, you know, before I was a terrible deep sleeper when I started to get it.

monitored and i said i got to work on this you know it was like averaging less than 15 minutes a night and then the one biggest thing i changed i made was this regularity and it really jumped up from that and of course um it's not easy to keep on a schedule um but it sure has made a big difference is that related to keeping on our unique individual circadian rhythm

Well, while we're on the wearables, there's several types here.

There's the rings, particularly Aura, that's got a lot of popularity.

There's the various smartwatches and mattress sensors.

I mean, there's a lot of different ones.

And have they been validated against the gold standard sleep lab for the different metrics of phases of sleep and whatnot?

I see.

Yeah.

I mean, I've been comparing for now a couple of years, a ring versus a watch, an Apple watch and a,

mattress sensor and the ring is the only one that seems to correlate with how I feel, which is really interesting.

Only recently did Apple introduce scores and they were pretty primitive.

The scores perhaps are not the best to rely on, as you point out, the changes in algorithms and different devices.

Now, I want to come back to that in a bit, but one of the people asked about sleep scores and I think it's an important question.

But everyone wants to get better sleep who feels that they're sleep deprived.

And there are supplements we want to talk about.

There's drugs that have been used characteristically that potentially make things worse.

And then there's the erection drugs that you touched on, and we want to get back to that.

Let's just talk about a few of these supplements like melatonin, magnesium, ashwagandha.
