This actually isn’t a joke. What makes us different from the un-dead creatures from spook-show zombie movies and the likes of Twilight vampires? Aside from value to society and a touch of class, the correct answer is a pulse. Every known living animal has a heart that creates a pulse of some kind. In fact, the pulse is the major criteria for determining the difference between life and death. That is until now.
Doctors Bud Frazier and Billy Cohn have turned what we know about the difference between life and death and made it a lot less simple. These doctors have made it so that 50 cattle and 3 humans now walk on the Earth without a pulse. Taking a daring hypothesis that just because ever heart has a pulse, we don’t actually need it, they developed a 10,000 RPM pump that creates a continuous flow without any pulse. Although these 53 cases all fit the criteria for being the walking dead, they are able to function normally.
