Ok, this is not necessarily a pleasant topic, but I need to know: where does ALL that snot come from when we get a cold? Im currently suffering one, and I feel like I could fill a bath tub with the amount of boogies that have come out of my nose. Where does it all come from? And it just keeps coming! I feel like Ive finally cleared my sinuses and not a moment later Im back to the sneezes. If my body just keeps on making all this snot, where is it doing so, and why? Also, whats it made of?
