Drain and reality.

Vampires - a legacy of the distant and ancient legends. Do they always existed in human consciousness or is it an invention of ignorant and superstitious community, especially when it comes to the Middle Ages? All the talk about their immortality, the great white strong fangs, unrealistic attachment to the blood based on the greater weight of the film, literature and other forms of modern culture and the media to the public. But the medieval tales of bloodsucking still differ from the modern. We examine all the arguments on the scientific.
Legend One: Death of old age is not so dangerous vampires.
This legend is especially played up in books and movies, where uppercase characters - the vampires have a rare duration dark life - several centuries. The flip side of shining medals immortality turns continued life vampires are able to death when they get out of the coffin but the passion for hunting to pounce on prey and swallowed her blood. Vampirism arose based legends, in the distant villages, but not so rare vampires held sway in the major cities. It is common knowledge on how human tissue during the life destroyed, and any vampire could not live a few hundred years, as his skin to dry, and the bones and muscles would ache unbearably. On top of a poor guy vampire would have developed some old man's disease, and he most certainly would have died from the aging of tissues. You can certainly argue that the vampire could rejuvenate from the constant use of blood. Let's porazbiraemsya second legend.
Legend II: vampires instead of food consume human blood.
The use of the notorious vampire burgundy liquid can be seen as an attempt to extract from it something vital to their existence. Vampires drink blood very often that makes me think that they restored it from there some element or energy. Nor in the historical chronicles, or in medieval literature about famous krovopivtsah like Dracula is no mention about the information that their real historical characters drank human blood. Still a mystery vampires and vampirism is hidden away in the blood.
Legend III: vampire fangs are, their skin pale as Grebe, do not favor the garlic and the sun.
Even in modern times, scientists have determined the existence of a unique disease - the notorious "disease Ghouls" or porphyria. The disease shows itself in the fact that the vampire - porfirika not produced red cells, it soon begins defective metabolism, following which the vampire has a pretty hard-hitting, and in specific cases, also very awesome look. Because of the lack of pigment vampires are pale skin and distorted features. Given their disease begins large accumulation of gas under the skin and accumulation of hemoglobin, which loses structure from contact with ultraviolet radiation, that is, the light of our heavenly body. This may explain the belief in vampires and vampire victim and photophobia.
Now we have found the answer to the question of why vampires need to drink so much bloody water of life - to supplement the lack of a vampire in the body red blood cells, which are not able to get a vampire yourself.
Legend of the fourth - the vampire is essentially synonymous with the revived ghoul.
There are also all very prosaic and simply explains the physiology of a corpse. Remember the signs Nosferatu - when you open the coffin, he has quite a youthful appearance, even blush on his face, vampires often found with traces of blood from the victims, sometimes even a vampire, "eat off" and look more complete, in general, as anyone with a standard diet. The difference between an ordinary man from a vampire in the coffin, if the person has recently died, and not so much. After the death of a corpse are gases that were in life. In addition, because of oxidation and decay of tissue synthesized gas, which is in contact with the inside of the existing, and therefore a little swollen limbs of the corpse and budge. It seems that the vampire dine and went in a completely different position. On top of gas creates a slight pressure, and of the throat, mouth, begins to ooze blood, which can also come out of the sinuses, which creates the impression of a vampire who has just had a drink someone's blood. So this legend and now there was only an echo of the dark age of ignorance.
