Hi Mary. I am sorry to hear about your husband's diagnosis and especially the family tie. I recently watched Noah Greenspan on YouTube. This video was very informative. Dr Kaner was a guest and he gave information that I had not seen explained in such detail before. Just as important was the other guest who at that time had had IPF for three years and what he was doing to keep himself as heathy as possible. That vid is 5 years old and I googled the guest, Bill Vick and he looks to be doing just as good now. He's part of PF Warriors and it's in TX I believe but they are on FB. A support system from others going through the same thing is important. I wish your husband, you and your family all the best.
