I think what's clear from that paper comes on to one of the fundamental conventional tips that we spoke about in how to optimize your sleep, not just an unconventional, but the conventional, which was, I told you, we are a dark deprived society and we need darkness at night to help...

keep our sleep regular.

So the sort of the R in the QQRT.

And I think there in that paper, the inference, of course, is that if you're getting dark at night, it's going to give you a nice sleep onset signal so that you are asleep at night in the darkness.

And that sleep at night in the darkness provides this beneficial, you know, sort of

not immunization, but at least palliative help to certain psychiatric conditions.

We're not suggesting that darkness at night, if you're awake at night, however, is beneficial.

That seems to be not beneficial.

But it was such a great paper and very elegant in how it dissected the independent nature of these things, which fits very well with, I think, your mission in part in life, both as a scientist and as an educator, which is how can I

curate information, gather it together, and give you some type of actionable boots on the ground, feet in the trenches advice as to what to do.

It was a great paper.

So thank you for bringing it up.

Such a good point.

And since it's only you and I here and no one else watching and witnessing this, I am thoroughly going to steal that phrase of junk light and help educate people because that's a perfect description.

It's like empty photons.

Yeah, you've all heard of junk food.

Well, there's something called junk light.

And if you get your whole foods during the day, just like you get your whole kind of encompassed light during the day, that's great.

But then if you start binging on junk light at night, it's profoundly deleterious to your sleep and everything that sleep depends on.

It's lovely.
