I take it you invented some baseless conjecture. As a casual suggestion try searching the web for "mouth versus nose breathing" and see what the results say.

I take it you invented some baseless conjecture. As a casual suggestion try searching the web for "mouth versus nose breathing" and see what the results say. One of my biggest complaints about software developers is that so many claim to be engineers, but instead of measuring things (which is what engineers do) so many invent their own conclusions that tend to be wrong almost every time. It's disappointing.
