Oprah says sitting down with Nobel Prize winner and human rights activist Elie Wiesel was a "privilege of a lifetime." This Sunday, Elie opens up to Oprah about his emergency heart surgery. "We get an opportunity to talk about those moments of him being on the operating table and his thoughts about who he was and all the things he had left to do, which was really surprising to know that at 82 years old he still felt like he had so much undone," Oprah says.
