Well Thank you & yes those 30 years have no doubt done damage especially those 1980's lol- I have had no Aveolar PAP testing no . I am thrilled to find this information out here in my own rabbit hole . I do recall having shortness of breath in the late 80's and grabbing the over counter mist . It became very prominent in 2016 that I was in serious trouble having my very first attack but it was not until this past year 21 that I landed in ER twice . I will definitely look into this amazing information . Big Thanks & Blessings to you . Greg
