As the population over 65 is set to outnumber those under 18, "Aging In America: Survive or Thrive" investigates whether the U.S. is prepared for this demographic shift. Using Dr. Robert Butler’s Pulitzer Prize winning book, "Why Survive?: Being Old in America" as a guide, the film explores issues such as ageism, healthcare, economic insecurity, and Alzheimer’s. © PBS (Public Broadcasting Service).
