Ok, so a bit of story time.
So, I've always had allergies, especially to cats. Nothing was ever diagnosed as asthma, but I tried to limit my exposure to them because of the effects. Those effects weren't a runny nose or watery eyes, they were difficulty breathing. Well, Kris and I start dating and she has two cats. Well, after prolonged exposure my breathing isn't going as well as it should. This has me fail a flight physical and sends me to Keesler AFB in Mississippi to undergo 2-3 days of breathing tests. Needless to say, I failed. Was finally diagnosed with a form of allergic asthma, which disqualifies you from military service, especially flying. So now I'm technically a "Disabled American Serviceman" per the VA, since this was diagnosed while in the military. Now, the VA also lists me as 0% disabled, so that's entertaining. Completely eliminated from all future military service, they couldn't have drafted me if they wanted to after that. Luckily, with some of the good allergy medication (allegra) and getting older, this is less and less of a factor for me.
Fun story, while getting drummed out of the service, I had to go to Lackland AFB, TX to meet with a medical review board. Lackland is the basic training base for the Air Force. Well, dumb 2LT me, decided it was a nice day (November in TX) and I would walk across base (at 5am) from the Visiting Officers Quarters to the medical office buildings. Almost immediately a couple of recruits see me, hop to attention, salute, and nearly scream "Good Morning Sir!" Scares the crap out of me. Now rinse and repeat 10x for the next 3/4 mile walk. Needless to say, I took the base bus back to my quarters.
