Being asked a uncomfortable question etc, thats when i have some kind of acid reflux thing and find myself quietly clearing my throat all day and depending on the severity or continuation leads to a strained voice or to loosing my voice.

Labouring under breath during training is a combination of clearing of my throat from time to to time and sucking in volumes of air (unless i don't put the effort in) This is where i know i should have more cardio endurance than i already have and its noticeable by breath.
I'm as thick as two short planks but i keep seeing the joining of dots between stress and its effect on breathing, which is made more prominent under higher loads such as cardio and endurance training.
