And the first thing people do is hold their breath.

Why?

Because they've created a little stable trunk to

requires less skill, less movement control, and they can simplify the system.

So if I just hold my breath, then I can do a skill for a while.

And what we actually, many of us are doing is going from breath hold to breath hold to breath hold to breath hold when we work.

And you're not actually limited by your strength.

You're limited by your ability to manage oxygen use because you're not breathing.

You're going from breath hold to breath hold.

And you'll see it and actually watch your kids, watch people like they literally are existing in a world where they're going from breath hold to breath hold.

And oftentimes we're like, oh, that's a curious strategy, given that we're aerobic animals.

And look, we establish it this way.

If we lay you down on the ground and I have you take the biggest breath in through your belly, through your ribs, through your chest, through your upper back, we could measure that, right?

But I call that the reference volume.

Because there's no load on your spine.

You don't have to do anything like you're out of gravity.

We can just like, what's the most errand we can get?

And we can practice that.

Put your hands here, breathe here, right?

We can measure that.
