Vampire physiology question

[shapinglight]

We all know the whole 'unneeded breath' thing is silly, right? We do, right?
Vampires may not need oxygen to live, but they do need to breathe in order to speak. Fine.

But does it make sense to anyone else (as it does to me) that their breath would feel rather on the cool side? They have no body heat of their own. They derive it from drinking blood. But does that warm them up so much their breath would be as warm as a human's?

Opinions, anyone?

It does make sense, and chimes in with what I wrote recently in one of my entries for the Fag Ends Anniversary Comment Fic Challenge, in which Spike told Buffy that vampires sort of shut down and hibernate when they get too cold (except that I think in my head, at the time, I thought he was lying).

What was this story called? Can you remember?

It was definitely a seasonal_spuffy fic... Maybe one of thisficklemob's?

Ah. I'll have to look it up. Maybe it'll give me an idea for what to write this round.

Nothing else has so far.
