at 1,500 parts per million because your body is struggling.

It's placing you in that state of stress.

Most airlines I've recorded are... We must have had it in my class then.

So one study I read from Harvard said that 1,500 parts per million, that's about three, four times higher than what the air is in the outside, right?

The amount of concentration of carbon dioxide is...

can create a 50% decrease in some cognitive tests.

So test scores.

If you think about what we're doing to kids, we're placing them in a classroom for eight hours at a time with air quality of 2,500 parts per million.

So well north of that 1,500 parts per month.

It changes all the time in areas that have nice climate, right?

You have these things called windows.

You could just open it.

You have a door you have opened up.

But a lot of new schools right now, just like new hotels, new offices, you cannot open the windows.

And what I've found is these offices and hotels do this to save money because it costs a lot of money to either heat up air or cool it down.

So instead, they just recycle things.

the same stale air, everyone's exhalations from room to room to room.

And I can prove this now because I cruise around with one of these things and I've got a small army of 20 other people collecting data.

And we're going to put all this data available for free that people can start seeing what the air quality is in these hotels and airplanes.

Yeah.
