(Illustration by Leah Abucayan/CNN) Jon Gluck was a successful writer in his 30s, married with a baby, when his doctor informed him that he had only 18 months to live. That was over twenty years ago. Now, Jon writes and edits for Fast Company and is the father of two children. He still has incurable cancer. Unlike many Americans, Jon was lucky enough to have health insurance and access to cutting-edge scientific breakthroughs.
