The worst.

Protocolize the living daylights out of that and do as much as I can.

So I think that's probably the end of the...

thermal story.

Although we are now trying to see if we can take lo-fi approaches where we're going to do some foot warming.

We're trying to develop some foot warming technology that can be built into maybe a mattress and some mattress companies.

There are some great ones.

I know obviously Mateo at Eight Sleep and they are

They are doing amazing things.

I think his company, again, I have no affiliation, but we connect very well and he's brilliant.

So they're doing something like that.

What about auditory?

Auditory.

So acoustic stimulation.

In a very similar way to...

electrical stimulation, where you're trying to target that deep sleep and see if you... A better analogy is probably a metronome.

And you're trying to see if you can kind of force the metronome further over and back and forth with these types of technologies.

But auditory stimulation came on the map again.

I think probably Jan Born's group in Germany was some of the first to do this.

They initially started with the same generalized approach where they would take acoustic tones and they would first assess what is your level of awakening threshold.
