Sorry Entropy but this is not always the case. You can have done your treatments to the T and never smoked or done drugs and STILL end up needing a transplant at 19. Just because you followed all preventative measures to stay healthy does not mean your CF is going to progress slowly and that you are going to stay healthy well into your thirties. If that were true, I wouldn't be in chronic rejection and waiting for a second transplant.
CF is different in everybody, even if they have the same mutations and do the same treatments.
Scaring happens after having multiple infections and usually with each infection your lungs scar a little bit, so eventually, after multiple exasterbations and infections your lungs become so scared that you come to the point when you need to choose to have a transplant or not.
