I consider myself mildy/moderate. I have been at my job 7 and a half years now, basically changing oil, tires, batteries, etc. I remember when I first started when I was aound 21 I used to hussle like someone put a firecracker in my ass. I was probably the fastest technician we had. I'm still pretty fast, but I do notice now I get out of breath alot easier. I just moved into my place this past October, and right after the move I had to be admitted to the hospital as I had serious lung inflammation. The doctor said it was not an infection. My father helped me move, and he is pushing 60, and I made him seem like an American Gladiator.<img src="i/expressions/face-icon-small-happy.gif" border="0"> I was constantly out of breath, gassping for air. When people say CF is a progressive disease, they're not kidding. I can tell a difference, however subtle it is now. In the back of my mind I worry about when I'm 40, or 50. I'm 28 now and I get out of breath pretty easily. I don't even know what my fev is, actually this is probably a dumb question, but what is fev?
