I'm 40, and my case had been pretty mild, I'd been active with a lot of stuff, I'd try to keep up with my little brothers-played Ice Hockey at the age of 9, until about 12 or so.
Got into the Martial Arts at 18.
But, about a year ago, my mom told me that the couple that introduced her to my dad (The matchmakers), the wife was diagnosed at about 60 or so with CF. How she's doing now, I forget to ask, but that's pretty old (and pretty close to home!) for someone to even be diagnosed with CF! (eh?)
I'm looking forward to my late 70's to Early 80's! Just hope I got enough S.S. to hold out all of my hobbies!!
