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?

That is a good question and one i have thought of myself. For now i have no answer. I can only surmise that the blood does warm them up to a reasonable temperature but still feel cold to the touch against a human. In relation to this if they are undead how do they think as the brain itself needs oxygen and blood to survive.

This, I suspect, along with the question I asked, is one of those things you're supposed down to vampires=not natural.
