The squeeze is constant, like a python.
Good point.
Funny you should say that - I was just thinking about the tactic of some pythons. They squeeze and you resist of course and you seem to be doing fine in the battle between human and serpent, but eventually you must exhale in order to inhale a fresh supply of oxygen. But the moment you exhale the python tightens to the max on your briefly reduced lung size - so now you can’t inhale more air. You try to use the air in your lungs but must once again exhale to expel air depleted with oxygen and again, they tighten. This can be subtle - you may just feel like you are ‘getting tired.’ They wear you down this way - they don’t have to ‘win’ in one mighty effort - it’s the constant, vigilant, vigorous squeeze.
