In January 1971 “All in the Family” premiered on CBS. Fifty years later, the co-creator of that classic situation comedy, Norman Lear, explains the importance of laughter in keeping him going strong at the age of 98. CBS News chief medical correspondent Dr. Jonathan LaPook (Lear’s son-in-law) recently spent time with Lear, making a home movie like no other, in which the legendary producer reveals what makes him tick.

Norman Milton Lear is an American television writer and producer who produced many 1970s sitcoms such as All in the Family, Sanford and Son, One Day at a Time and its 2017 remake, The Jeffersons, Good Times, and Maude.
