Vampire social dating
Personally after my change I've been consciously aware of that going on and am wondering if this is the case for other real vampires.
When we are about to fight, the sympathetic takes over and norepinephrine (adrenaline) pours into the blood, causing the circulatory system to be affected.
Since this may also result in pain receptors working harder, we would be more sensitive to types of heat and other forms of pain. The body naturally creating endorphins to counteract pain would naturally adapt and produce either stronger endorphins or endorphins at a higher rate.
This would result in a higher control over pain in the long run.
Allowing neurons to create more connections without loss of speed, and the 10,000 miles of blood vessels in the brain doubling as an additional cooling system for the brain.
I could write a book on the cascade of effects that alone causes for people when they are changed in to a real vampire, however for now I will leave it in this simplified form.
If we, as real vampires, were in a constant state of that, seeing that a good portion of our body would feel the lack of blood it does make sense that we would feel the constant need to get blood from an outside source to feel reasonably normal.
We call these people posers, which they are; they are confused lost children. It is for real vampires, curious people, and open-minded skeptics.
Making stomach acid completely irrelevant, as for recognizing blood I'm pretty sure the body knows what blood is.
If you think a vampire or even you can drink blood without that blood or part of it being absorbed in to the body before it reaches the acid in their stomach.
Some say that is an overly simplified form of how the brain functions, which it is.
To them I say make the axons 12-15% wider, resulting in signals being sent much more quickly through the brain.
