My son is 65 and has what the lung doctor said is Asbestosis (evidently he breathed some in at some time) and is using inhalers all the time. Now the lung doctor perscribed a neubulizer also an oyxgen concentrator. He is not over weight. In fact he was losing weight.
I think being diabetic might have played a big role in your friend not surviving. It seems to me diabetics are at a grater risk from other health issues then most people would be.
I agree, Spunky. I think it was the diabetes that harmed his chances the most.
