About the diabetes thing, it can be fatal if you don't take care of yourself, while I am not diabetic, I do have kidney failure, it is most definately fatal without kidney dialysis. Most diabetics pass away from complications from the diabetes, like kidney failure (and not wanting to do dialysis). If they don't take care of it, they may not live long enough to make it to the kidney failure stage, heart attacks and other complications will arise.
