Only on the "CBS This Morning" podcast, legendary television writer, director and producer Norman Lear joins his daughter, Kate Lear, and son-in-law, who happens to be CBS News chief medical correspondent Dr. Jon LaPook, to discuss some of the life philosophies he's formed over the years. Lear, who is 97, shares how laughter has been the most important factor allowing him to age gracefully. He explains how he has managed to find common ground with people he doesn't agree with and the importance of keeping an open mind. Plus, Lear shares why his six children are able to reach him no matter what he may be doing and how we can all benefit from his mantra of "over-next."
