Funny -- I was talking to a guy via AIM/Yahoo who believed he is a vampire. Somehow it sounds like the same guy, too..

Are vampires in biological terms capable of surviving without blood. They could be like bacteria just really big ones. DO vamps exist? Biological?

Vamps exist (it's a slang word for someone bisexual).

Vampires, as a biological organism do not. Culturally, some humans make a practise of drinking blood, but they get no nourishment from it that they cannot get elsewhere.

But they definitely cannot survive on blood alone, can they? It would be drinking just water. Sure, you can live for quite a while with just that, but you'll get quite skinny.

Besides, didn't this "blood lust" originally came from the idea that you can reach immortality in Indian, Greek, and Christian culture? More of a religious practice then, I'd think.

Correct. While blood might fulfill some dietary requirement, it by no means is able to sustain human diet alone.

I'm not sure on the cultural aspect...I've studied many religions, but not Vapmyrism.

I thought that blood had tons of dissoved nutrittuents. So it might be possible to live off blood.

So does beef, milk, water, and other types of food. However, living off just one kind of food would not keep you alive for very long. Unless, that is, if you are willing to eat a lot of that particular food just to take in ALL of the nutrients necessary to keep you living. Personally, I'm not sure if anyone with the practice of drinking blood would want to drink gallons and gallons of it everyday.

Enough blood in your stomach, and your body will force you to vomit. I believe the threshold is a quarter cup.

Inuyasha wrote:Here's an interesting problem. What color is blood. I know that when it has oxgyen attached to the hemogoblin it is red but what if there is no oxygen as in a vein. Hmmm. Since veins are blue does that mean that blood without oxgyen is blue?


Blood is never blue, contrary to apparently popular opinion.

http://en.wikipedia.org/wiki/Blood

"Human blood is red, ranging from bright red when oxygenated to dark red when not. It owes its colour to hemoglobin, a metalloprotein compound containing iron in the form of heme, to which oxygen binds. There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin. Moreover, the blood inside is dark red and exhibits poor light reflection. From a physiological perspective, veins and arteries appear similar when skin is removed and are seen directly."

considering what Inuyasha said that

wouldn't the person's diet matter? I mean if you have different blood sources the nutrient content would also vary, right? and maybe the nutrients might be enough to support the vampire...what do you guys think?

Of course the diet of the person whose blood you are drinking matters. If you drink the blood of someone with a balanced diet than you might be able to live(you would need to drink a lot though). if you are a vampire than that means that your digestive system is adapted to blood... So why not... theoretically vampires could exist...
But this is a somewhat stupid conversation, wouldn't you guys say so?

In the last 4 months I've seen postings in several forums about the
dangers of drinking blood. They fall into three categories:

1) HIV (real danger, but avoidable)
2) Drinking human blood makes you puke because you can't digest it (if
you puke its psychological - your stomach doesn't know the difference
between human blood and steak juice)
3) Weird blood-borne infections (such as this Staph Aureliens thing)

Look, folks, blood is blood is blood. If you eat meat, you eat blood
(kosher meat having most of it removed). If blood went "bad" in 15 to
20 minutes from exposure to air we would all die from eating ANY meat
(except the vegetarians, of course) cause it takes DAYS for meat to
travel from the slaughter house to the supermarket to the dinner
table, sometimes weeks. Yes, there can be nasty things in blood, and
it will spoil like any other animal-derived protein, but this business
of DRINKING BLOOD WILL MAKE YOU DIE A HORRIBLE DEATH IN 12 HOURS OR
LESS IS BULLSHIT!

In this regard (on the physical as opposed to psychic level) human
blood is not significantly different than any other animal blood.

Don't worry about oral sex and menstruation - as long neither of you
have any STD's you're both safe. Oh, by the way, if you have cold
sores restrain yourself - you wouldn't want to give your lady friend
genital herpes. Other than that, have fun.

Consider this about the supposed mechanism for this S. Aurelius
poisoning:

This bacterium is allegedly found fairly commonly in the bloodstream.
There is a term for the condition of having bacteria living free in
the bloodstream. This is called septisimia. It is usually fatal
within hours.

As well, if these bacteria were present in the bloodstream and
produced a toxin on exposure to oxygen, then they would do so in the
bloodstream, since the blood is reoxygenated in a human every minute
or so on average when it goes through the lungs.

This whole notion is simply garbage.
