"When I was born, I had a life expectancy of 5 years old," she once explained in a September 2015 video. "And then, it moved to 10 years old. And then, it moved to 13 years old. And then, it moved to 18 years old. And now, it's currently at 19 years old. And every single time that I get close to that point where I'm supposed to die, there's a new technology that comes out, new medicine, new ways of treating cystic fibrosis. And then, presto, I live for another five years. But, really, at the end of the day, I can't believe what the doctors say. But I also can't believe it's going to be OK."
