Leeches. Vampires are leeches.
(Haemophagia is a metabolically marginal dietโblood is notably short on nutrients!โso all actually-existing haemophagic species are highly specialized. I once did a BOTE calculation and worked out that a human-size vampire would need to bleed about one victim per hour completely dry to avoid starvation.)
I doubt that vampires run on chemistry. They run on zero point energy. Blood is for being sexy.
There was a British vampire show called "Ultraviolet" in the late 80s in which the word vampire was never used: they called them leeches or 'code fives'
Hmm. So what's the explanation? My first thought was total conversion of the iron in the haemoglobin to energy. 3-4g in the whole body, say about 250mg in one blood meal... gives about 6 million kWh. Do vampires traditionally emit mostly in X- and gamma rays?
What would it take if vampires were cold blooded?
@georgetakei Makes sense really. I was still surprised when I first saw the concept realized in Darkest Dungeon - Crimson Court:
Pathetic - this Woman really knows absolutely nothing about #Vampires.
She should read #BramStoker (if she can read then... )
