I found that if my tongue doesn’t block my mouth I can only breathe through my mouth and if it does I can only breathe through my nose.
Huh, this isn’t what happens when I try it. If I keep my tongue out or at the base of my mouth, I can still definitely choose whether to make the air go through my nose or mouth. If I try to block my mouth with my tongue, that does obstruct the airflow through my mouth but I can still breathe mostly okay (even if I plug my nose).
