For Matthew Zachary, the subject of cancer is up close and personal. He was diagnosed with a rare brain tumor at the age of 21. Having survived the odds, Zachary became a patient advocate, founding a non-profit called Stupid Cancer which supports young adults with the disease. Zachary celebrated the publication of his memoir We the Patients, by sitting down at the piano on the stage of Manhattan's Merkin Hall and playing a concert. The event marked the 30 years that have passed since Zachary's cancer diagnosis. We talk about family, wellness and how to be a healthcare revolutionary. "Now What?" is produced with the help of Steve Zimmer, Lucy Little and Jackie Schwartz. Audio production is by Nick Ciavatta.
