> yawning is not simply an intensified breath but a distinct cardiorespiratory manoeuvre that reorganizes neurofluid flow

Brilliant, I'll use that next time I yawn somewhere inappropriately.

Yawning is so baffling, I woke in the night to yawn yesterday. I was turning over in bed and suddenly found myself yawning enough to perk my sleepy awareness.

Distinctly remember being outraged.

Makes more sense I suppose if yawning isn't just signalling sleepiness to do it even while asleep!

I've just reorganized my neurofluid flow, that's how I feel about this.
