About a hundred years ago, Dr. Duncan McDougall conducted an experiment on a handful of dying people. He concluded that at the moment of death there was a weight loss of twenty-one grams. He believed this was due to the soul leaving the body. By way of comparison, the typical bullet used in an AR-15 semi-automatic rifle weighs about four grams, a bit less than a nickel. The next time you pick up a nickel, heft it in your palm. That’s all it takes to wipe out a soul. Well, that and a person who has already lost their soul.
