I read somewhere that even if in an non-congested state, you only PRIMARILY breathe through one nostril; one nostril will take in more air than the other. Supposedly so if you encounter something hazardous to the tissue that one passageway isn't affected as bad and takes over.

i already knew it but now imagine if there is some kind of plan b for this where else does our body have a second way to deal with problems? like if your nervnode for your heartbeat somehow fails there is second one to keep you alive (sinoatrial node and av node)
