Breathe through your nose for better health.
This version's text is easy enough to read. A modern take is the book Breath by James Nestor; read this instead, unless you're interesting in Catlin's view. In short, the nose is our primary way to breathe, with the mouth auxiliary, and there are health benefits to breathing through the nose (and health detriments to breathing through the mouth). Chewing tough food is important for expansion of the face to facilitate nasal breathing. Catlin bases his observations on some indigenous North American cultures. Use it or lose it. Tape your mouth shut at night, vertically with a 1cm-wide piece of medical tape (easy to remove, minimal residue), to condition your face for nasal breathing and to reduce exposing the teeth and gums to gases that promote plaque.
