Do Vampires drink your brain through a straw up your nose?

But they love proteins

I understand that , but by tradition they can only sustain their undead life by consuming blood.. That is what their body craves and lives on. Yeah I know slitting hairs.. If they were sucking out the brain they would necessarily get blood too, but not the amount that is available from the carotid or jugular.. nearly 1/2 diameter tube under pressure.. Lol. Master1A
