Diabetes II, is a main one and they usually get 50%. At least, most of the guys I have helped here in Missouri. If you have more things wrong that are connected then that makes it better for a higher rating. Some things that are over looked by most of us is miscarriages, this is also signs of exposure, some birth defects. We just have to stay on top of all the new stuff they are adding..
