Hello. Thanks for your reply. I was stationed at NAS Oceania from 1980 to 1984 and lived in the barracks with a roommate that smoked for the first two years I was there. I also worked at PSD and at that time it was still acceptable to smoke in doors. Because I worked customer service I was constantly being exposed to lots of viruses. I also had to walk to work in the cold due to not being able to drive at the time and the barracks had inadequate heating so it was always cold which mean I was always sick with a cold or allergies.
