I'm 59 just found out that I'm pre emphysema . I was on site that were talking about longevity and I was scared but reading these post really help me out.. I smoked when I was seventeen for a couple of years that was it . I think I got mine from pneumonia since I was in my twenties always getting pneumonia year after year well it left a lot of scarring that is how I think I got mine. Thanks to every one posting I feel I just might see my grandchildren grow up. I had a good cry today now its time to do what I need to do.
