Turns out it takes a lot longer for a vampire to drink your blood than Hollywood’s best guesses.
How can we know? A group of University of Leicester did the math. They estimate it would take just under six and a half minutes for supernatural bloodsuckers to live up to their name.
Bear in mind this doesn’t account for every drop of blood in the human body.
“Any more than 15% blood loss and the heart rate starts to change,” the students’ findings explain. So if noted video game star Dracula went for the throat that’s how much he’d be able to reasonably get at without “slurping” his drink, so to speak.
