I've been around 30% fev1 for the most part of my life, I think from when I was 7 finally had my transplant when I was 22. It slowly went down when I was very little and I think that is why my nbody adapted to it very good. I still did a lot of the things that my friends did too. It got less and less with time. But all I can say is that every body is different. I think that you do have to look at your numbers, regarding transplant. But, I think it's good to look at what you can still do too. Transplant is no guaranty and no cure, you trade in one thing for another. And if you still feel like you have a good life I think I would grab those years while you can.
