This is the end of life for animals that are consumed for food. The Humane Captive Bolt or Stunner is used to kill the poor soul. But they are stunned and not always gone. They need to keep the heart beating long enough to drain the blood out. The idea is to kill the higher brain function and leave the hind brain intact until they are to bleed out. This one way of ending the life of these sentient beings. Still want to eat Animals?
