Sharp Intake If Breath / Stretch

[Bazile]

1. You are sitting there doing whatever - you suddenly take a sharp intake of breath

2. You suddenly feel the need for a stretch

What is the reason for the above ?

[Bazile]

Is there a physiological reason ?

[Sqad]

No idea.

[4candles]

Purely conjecture -
Perhaps the primeval region of the brain is prompting the body to do what's good for it - aka 'instinct'.

[Bazile]

sqad - what do you mean you have no idea - are you a physician or what ?

"sqad - what do you mean you have no idea - are you a physician or what ?"

[Bazile]

What's one of them then ? :-)

[Sqad]

Not one of "them", you can be sure of that ....;-)

[SparklyKid]

I do that all the time. Bit like yawning I suppose.

[Khandro]

As Tommy Cooper would have said, "Don't do it"

[Bazile]

Why do we yawn -is that also a mystery ?

[Mamyalynne]

In a way it's a mystery as there is no one particular reason.

[Bazile]

I'm talking about a physiological reason

[Tilly2]

Instinct?

[Tilly2]

Survival?

The body deciding that it needs oxygen and the muscles warmed up in case of sabre-toothed tiger attack?

Other predators are available.

//Why do we yawn then?//
Boredom for one

[douglas9401]

There was a guy, really tired all the time, worked in our local Indian takeaway.

Yawning Qasim they called him.

Deep.
