Everyone's talking about the outside.

No one's talking about the inside.

And the reason why they measure CO2 inside is if we're all sitting here and the CO2 levels keep going up in here, that's not from a coal plant or exhaust from a car.

It's from our exhalations.

So when you're measuring CO2, you're measuring how many other people's exhalations are in the room.

So at a CO2 level of around 2,000 parts per million,

which is found in a lot of schools and offices, about one in every 40 breaths or so is someone else's exhalation.

And if you get up to like 4,000, 5,000, it's one in every 10 breaths is someone else's exhalation.

So I started cruising around.

I travel a lot like you do.

I'm always on airplanes and hotels and all that stuff.

And I always feel like crap in these hotels.

If you've noticed, new hotels, they've glued up all the windows.

Back in the day, you're too young to know this, but back in the day, you used to be able to open a window.

Maybe not all the way.

You used to be able to take your own life.

Yeah.

Well, I think back in the old day in the 50s, you want to take your own life?

There it is.

That's your thing.
