ADVANCE FOR USE MONDAY, NOV. 16 - In this photo taken Aug. 20, 2015, John Jay Hooker listens as Dr. Kent Shih talks about his treatment options for metastatic melanoma in Nashville, Tenn. "I’m going to hang in as long as I can and I will have to get exponentially worse for me to say goodnight because I still feel useful," said Hooker, who has rallied to the cause of physician-assisted suicide."I feel like I’m making a contribution."
