21-year-old Laura Rothenberg has always tried to live a normal life, with lungs that often betray her, and the sober awareness that she may not live to see her 30th birthday. Laura was born with cystic fibrosis, a chronic disease that affects the lungs and other organs. Most of the kids with CF that she knew growing up have already died. For the last two years, Laura kept an audio diary of her life, documenting her battle with the illness: from the deterioration of her lungs, to the decision to seek a transplant, and, if all goes well, more years to live and a lot less coughing.
