Hey MM bro, Not to go tangent to your posting, but the phenomenon of Vampires and Werewolfs for that matter are not the whimsical ideas we have in our heads. Infact, less than one percent of population in this world suffer from these kinda disorders. It is unfortunate that we don't consider these as diseases but discard them as some kind of supernatural phenomenon. If my memory serves me right, the people deemed as vampires have deficient of heme (iron) in their blood, so it is almost natural for these people to crave for blood (or at least seems like). If you have read about the vulcans of the past, their blood is believed to have been green and them to be some kinda abnormal people. But the fact is that the excess of magnesium makes the blood appear green. I have often wondered bout the mysteries that exist in the world and how easily they can be explained provided we are ready to accept natural explanations (science for that matter) than cling to our fantastical dreams. :). On final note: what happens when a he vampire meets with a she vampire?? LOVE AT FIRST BITE!
