I have a cold nose, and I don't think it means I'm healthy.
My nose is cold and aches. I don't think it's doing the "warm the air" thing properly because when I breath in the air feels cool against the back of my throat, and the roof of my mouth feels cool. The only relief comes from drinking hot water (plain, no coffee) and I'm drinking buckets of the stuff. Not that water will hurt me or anything and I'm starting to piss clear.
I woke with a headache this morning. It's going to be one of those days.
