My brain’s been wandering lately, and never moreso than last night, when I was left pondering Vampires. Guided by my insomnia, I started wondering — how do they work, exactly? I mean, I get the whole pointy-teeth-to-puncture necks thing, as I’ve got a fairly fearsome set of canines myself. I get the whole aversion to light thing — I’ve known more than my fair share of programmers. I’m not quite sure about the garlic, crosses or flowing water bits, but those seem to be more flexible items of Vampiric lore than the basic biting business.
And what I don’t quite get is why it’s so common in Vampire literature for the resident bloodsucker to keep the fangs engaged in order to feed. Are Vampire’s teeth basically hollow straws? Why couldn’t they dis-engage the fangs and therefore get more suction on their victim’s necks, and a better feed if it’s all going down their throats anyway?
