I was talking with my brother who shoots a lot but doesn't load or cast, and he came up with another danger of bullet casting. As he put it (Ok, ya gotta be uncritical here): The lead dust (none present, I know) gets in your lungs and weighs you down, you go on a diet to loose the weight but keep on casting, end up weighing more because of more dust in your lungs. In a panic you quit eating, and bullet casting causes you to starve to death!
Not bad for off the top of his head.
