I suspect that chewing cobs in a daily basis will positively effect the health o the oral cavity.
That alone would cause me to stop worrying about my rotted and syrupy lungs, the poorly functioning kidneys, and the nearly atrophied liver, lol, and to start eating COBs as quickly and as often as I used to eat hot dogs when the local slop shop still sold them 12 for a dollar - and without worrying that something in them might make a man sicker (again, like those hot dogs ).
That's assuming I went to sleep and woke up in a reality where the things fell from the skies like rain, of course.
