From a story on gq.com by Zach Baron headlined “Martin Scorsese: ‘I Have to Find Out Who the Hell I Am'”:

For years, Martin Scorsese would ask himself: What will happen when I get old? As a child, Scorsese was often sick with asthma, and as an adult, he spent a good part of his 30s weakening his heart, through excess and exertion, to the point of ending up in the hospital. Mortality has always been a specter in his life, and particularly in his films, which are a vast record of violent and untimely endings. But this recurring question wasn’t about death. This was: What will happen when I get old? What kind of work could I do? he would ask himself. Would there be any more depth?
