Best-selling author Buzz Bissinger has relived the birth of his twin sons for nearly three decades. Gerry came first, weighing just over two pounds. But Zach, born three minutes later, suffered brain damage from a lack of oxygen. Gerry had no serious complications –- he became a teacher and is studying to earn a PhD. Zach bags groceries and will likely do so for the rest of his life. But while Zach accepted his 8-year-old comprehension skills, his father struggled to do the same. Buzz’s youngest twin remained a mystery to him until the two men took a cross-country road trip together. Diane and her guest discuss how he found peace with the fact that his son will never grow up.
