>How can you breathe if it's not visibly open.
I theorized that it may be very slightly open, or be open only temporarily, and I may not be aware of it at all. It's not like people that breathe through their mouth do it out of some conscious choice, I can see how you could develop that habit and not realize it, it happens very gradually and the brain is sometimes bad at noticing that sort of thing. the reason I thought I was breathing through my mouth is because I can feel a waft of cool air passing though my throat when I breath, but that air must not be coming in through my mouth
