To Loving Girlfriend..........Life with CF is different for every patient. Myself, I am 31 and I still continue to play hockey and try to work-out on a regular basis, or as much as my lungs and body will allow. My doctor has always told me to try to keep that up because it can always be to my benefit. At 31, I have obviously noticed a significant change in my lung capacity and I seem to get winded a little easier, but it has not stopped me in attempting to do the things I have been doing since I was a child. My brother also has CF and has also been very active throughout his life. Oh and I also have a cousin with CF. I still have to use a Nebulizer (to breathe in meds) every day and unless a cure comes soon, I will probably have to for the rest of my life in order to keep my lungs as healthy as I can. Unfortunately, not everyone can be as active as we are. I personally know a couple of people who have gone through double-lung transplants because their lung capacity was so low that they couldn't even walk up a flight of stairs without being winded. I'm not sure if this will help at all, but it's not exactly an easy and straight-forward answer to the question "What is life like with CF". For some, it is HELL. For myself and for others, I must say that it does suck, but I try not to let it effect how I live my life or how I look at my future. Sometimes that is very difficult to do. For you all I can say is try to live everyday to the fullest with him, as I'm sure he tries to on his own. Find out as much as you can about CF to help you understand where he is coming from when he feels a certain way. My wife of 8 years probably knows more about CF and the meds that I am on than I do. Maybe thats because I tend to get into a groove and do what I need to each day. You tend to forget why you take certain meds or do certain treatments. Having someone there beside you who understands and can support you through anything, is a great help and an even better motivator to stay healthy. We have been married for 8 years, own our own home and have made a pretty good life for ourselves. I don't know if I would be where I am without her. Hopefully this helps answer your question.
