AARP began as an advocacy group for older Americans concerned about Social Security, Medicare, and family caregiving. Today it represents 110 million Americans in the 50+ demographic who are living longer and retiring later. “Sunday Morning” national correspondent Robert Costa talks with AARP’s CEO, Dr. Myechia Minter-Jordan, and editorial director Myrna Blyth, about the organization’s importance to an increasingly important target group for advertisers; and with actress and talk show host Drew Barrymore, who at age 50 has embraced being on the cover of AARP: The Magazine.
