Ezekiel Emanuel — bioethicist, oncologist and author of the new book “Eat Your Ice Cream” — talks to WBUR's Deborah Becker about how to separate interventions that improve longevity and quality of life from those that don’t. This conversation was a part of The WBUR Festival (2026), where thousands of attendees descend on Boston each year to hear movers, makers, and other fascinating people in conversation with each other and with WBUR.
