There's one other thing that I just can't reconcile. Look at the issues our military vets from Iraq or Afghanistan are suffering from, specifically the burn pits. A lot of vets are sick or getting rare diseases that many people believe came from the constant burning of garbage outside of the camps/bases. Then look at the number of WWII vets that are still around today, 80ish years later. If the crematoriums were going 24/7x365 the amount of ash in the air should have done the same thing to everyone in theater.
