Ear Wax and Bugers

Ewwwwwww. I have some gushy shit coming out of my ear right now. Ear infections suck. During the fall I had some crazy allergies going on causing a running nose constantly. Attractive right? From what I understand our ears and noses make these fluids in order to expel foreign objects from the body. Pollen, dust, animal hair, etc. Then the ear and nose, even when the object has been expelled get confused and forget to stop creating the fluid. WTF?! Shouldn't our bodies be a little smarter then that? Shouldn't they know when to stop creating fluids, whether it's the liver or the ear or the eye or the gallbladder. Secondly why can't our brains control that? Our brains control our hands and mouths, but not our inner workings? They don't control our heart and ears. How weird is that? That our brains can only control parts of our bodies and the rest are on autopilot? What does control them, different parts of the brain or do they just work because of the blood flowing through them? Odd way to state that, can't think of another way to word it though. But whatever the case may be, what controls my insides?!
