I don't believe anyone can. You will have to start with some unprovable assumptions either way, so to say that you have really found out the ultimate purpose of your runny nose would be bullshit.
Which is why I said you should stop bothering yourself about those kinds of why-questions, they're unanswerable. Go enjoy your life with something more fulfilling and/or productive.
