The human body is miraculous and stupid.
You might think if we got sick in the wild, we might, you know, develop some sort of actual protection against further sickness. Instead, the body decides to make noses run. I don’t get it. When you can’t breathe well to start with, how the heck are you supposed to breathe when your nose is stuffed? Through your mouth? You mean, the thing that has no protection except tonsils against further infection? Tonsils, which can themselves easily get infected? The cycle seems intent on ridding the world of sick people, instead of ridding people of sickness. *sigh* I guess you could say that noses….. blow.
