I don't know much about decrease in FEV1, but I think lightNlife has it right - we get so used to functioning with crappy lungs that it's really difficult to notice the decrease in function. The body has an amazing ability to compensate for and adjust to certain losses.
But Ricky123, wasn't it you that started that thread about level of compliance? I believe you said you didn't feel it was necessary to practice 100% compliance, that on a scale of 1-10 you gave yourself a 7 or 8 (I think) and that you felt that was perfectly acceptable. Perhaps this way of thinking could be a contributing factor to your rapid decrease in lung function over the past couple of years?? I felt exactly the same way until I read through that thread and listened to what others said about it. Since then, I've been a 10 and I will never go back to giving myself anything less. Perhaps you should reconsider your views on the subject as well.
