Random observation

When it gets cold out (i.e. below freezing), and I breathe through my nose, there's a part of my palate (the roof of the mouth) that gets REALLY cold. The rest of my mouth is a normal temperature, but that one spot in the middle of the roof of my mouth is noticeably colder. I'm sure it has something to do with the way the nasal passages fill the bones above that part of the mouth, but still... it's kind of cool, and it's something that I never really paid attention to before.
