When you have a runny nose/cold, where does all that never-ending snot come from?

Answer 1

As an aside: On cold days when your nose gets cold it can actually get cold enough for the moisture in your own breath to condensate on it’s way out of your nose (or moisture from the air when breathing in) the further your nose is away from your face the more of an issue this becomes..

I have a decently sized schnoz so if it’s cold out I carry tissues regardless of if I am sick or not!
