    I am 56, I have smoked for 40 years (I have stopped it one year ago). I do not have the worst one which I believe is zz Alpha-1, but the one close to it. I am currently taking the medicines prescribed by the doctor. My breathing is becoming worse as days pass. I do not think it is appropriate to ask about the life expectancy. I am not a candidate for lung transplant as I am suffering from hepatitis C.

      It is good that you have quit smoking. Although the damage that smoking has caused to the lungs is not reversible, you should not lose hopes. You should also avoid second hand smoking as much as possible. Also reduce contact with persons who have respiratory tract infections. Create an exercise program after discussing it with your doctor. Eat healthy and nutritious diet to raise your immune system. Maintain good personal hygiene.
