We need that pressure and we need that filtering.

So when that air comes into our lungs, it is cleansed of all the pollutants that are in the outside environment.

And if you don't, you're much more susceptible to have respiratory infections.

I was a mouth breather my whole life.

You're in an environment with a lot of dust, with a lot of pollen.

This is going to exacerbate that inflammation.

If you were having a huge bowl of food, is it better to eat all of that food in three minutes as most people do?

or to calmly eat that food over the course of a half an hour.

You can digest it so much better.

The lungs are working in the same way.

All of these different structures in your nose that are built to slow this air down and to filter it, they are there for a reason.

We evolved to have these.

So when that air enters our lungs, it enters more slowly and it exits more slowly and it is pressurized.

That allows the lungs to absorb so much more oxygen than just going... And that's the main key.

There's so many other benefits, but if you're talking about just the foundational part of the efficiency, that's it.

You can breathe fewer breaths...

slower breaths and get so much more oxygen than you could, which is why it drives me crazy when people are at altitude.

They don't know better, so I'm not blaming anyone.

Or if they're exercising and they're jogging, it's sort of a medium pace and they're just thinking they're getting more oxygen.

They're not.
