JWS don't think of the implications associated with a world where everybody else just died except them They simply don't. All they think about is the pretty pink images in the magazines where you see a big BBQ with everybody smiling in a grassy hill surrounded by flowers with a leopard and a sheep playing together in the background. It's surreal.
Even the job of cleaning up all of the dead bodies is somehow delegated to the wild beasts of the world, who somehow will have to eat 7 Billion dead bodies before they decompose to the point they become a health hazard.
When this happens, who is going to run all of the systems that JWs depend on? Water, electricity, gas, etc? Who will run the power plants? Angels?
with supermarkets now empty, where is food going to come from? I'm willing to bet that close to no JWs know enough about food growing. Is Jehoober going to make food rain from the sky?
