Wearables track us.

You have smart mattresses, which are wonderful for understanding.

So there's so much you learn from a smart mattress and ways of also both measuring as well as intervening to optimize your sleep, which is the beauty.

And it's this nice, incredible period of time where you can measure so many things.

But, you know, in our home, so I use the example of a thermostat, right?

It's pretty, you know, frankly dumb about what my goals are or what I'm trying to do at that moment in time, but it doesn't have to be.

And there are, you know, there's a company, Passive Logic, I love them.

They actually have, I think, some of the smartest digital twin HVAC systems, but...

You know, their sensors measure things like sound.

They measure carbon dioxide, your carbon, your CO2 levels.

Like when we breathe, we give off CO2, you know.

So imagine, you know, there's a dynamic mixture of acetone, isoprene, and carbon dioxide that's constantly exchanging when my, you know, when I get stressed or when I'm feeling, you know, depressed.

happiness or suspense in my state.

And that dynamic sort of cocktail mixture that's in my breath is both an indicator of my state, but it's also something that it's just the spaces around me

you know, have more information to contribute about how I'm feeling and can also be part of that solution in ways that I don't have to have things on my body, right?

So I have sensors now that can measure CO2.

You can watch my TED Talk.

I have given examples.

We brought people in when I was at Dolby and had them watching Free Solo, you know, the Alex Honnold movie where they're climbing El Capo.

So carbon dioxide is heavier than air.
