Very interesting comments! I have had intermittent breathing all my life!!!!! It is like having sleep apnea while awake as well!!! Saw respiratory specialists from when a child---and as an adult and have had sleep apnea testing---no worries----makes no difference to life as the body gets the air/oxygen it needs by breathing when it needs to!
When I am speaking at a conference, or with a person, or am walking, it seems I breathe normally. When at rest, like reading, watching TV or even actively making meals --I experience intermittent breathing. So at times my body makes a great big uhhhhhh to get air and then that is that. I am over 55 , had it all my life and has not caused me problems as am used to it .
