Snot vs Acid

I'm getting over a really bad cold, so for the past week and a half I've been blowing Olympic amounts of super industrial strength snot. Even though I'm feeling much better, I'm still blowing. Where does it all come from? And, how can a body feeling so bad produce so much?

Spider man is a rank amateur; if I had been slinging snot I could have traveled the Manhattan skyline back and forth a thousand times. And don't even get me started on the effect of that snot on bad guys, because we all know how bodily fluids freak out guys. Why is that? They will play ball in the mud, dive into engines full of grease and oil, laugh at their own production of noxious gas, but let someone get sick and a few fluids show up and you'd think it was nuclear waste mixed with acid.
