In European and Chinese folklore, Vampires are creatures that look like men but are actually sickly pale-skinned undead that feed upon the blood of the living to sustain themselves, fear the sun, fear the crucifix, and require permission to enter your home.
Best of all, if you are being chased by a Vampire and you drop some coins, he must stop to pick them up.

Ashkenazi Jews are afflicted with common and severe genetic diseases such as Tay Sachs and allergies to sunlight. Tay Sachs impairs the ability of the blood to break down fats in the bloodstream. Oxygen starvation causes weakness and damage to muscles and the nervous system resulting in violent and schizophrenic behaviour and eventually death. It can be treated by regularly transfusing donor blood into the patient's bloodstream thus allowing the donor's blood enzymes to break down the fats building up in the patient.

It should also be noted that the Talmud (the Canaanite holy book) is built around themes regarding the blood sacrifice of children and the consumption of this "consecrated" flesh.

But of course, this must all be a (((coincidence)))...
