So that's the real missing piece.

Now, once you know what you're looking for and you start to correlate the data that we constantly exhaust with disease or with health states,

You have to build a device which anybody can have and hold that can tap into that.

And you actually probably use different technologies for collecting the gold truth data versus the stuff that's pervasively available.

So we're probably at the state now where we can do a Framingham study for cents.

We're not at the state technologically where anybody can have a device the size of a coffee cup or a cell phone that can actually detect that.

You'd still have to go into the laboratory.

We have devices that are pretty good, and they're about the size of two shoeboxes, but we don't know because we haven't done the dataset collection.

We don't know if they're good enough for disease detection.

So there's still more work to be done.

Yeah.

Boy, I mean, here's what I've learned about smell over working on it and thinking about it for a while, which is what's on the inside gets to the outside.

And there's a reason why a big chunk of the middle of our face is dedicated to analyzing it.

We have noses that don't seem to be getting smaller over evolutionary time.

They're not like appendices.

We need them.

There are private spectrometers.

And there's a reason why some things smell tasty.

So the things that smell delicious, we're detecting the molecules from the roasting meat or ripe fruit.

The molecules that smell delicious are directly derived from the nutrition inside of that thing.
