Ashton Applewhite is on a mission as old as humanity itself -- to change our attitudes about age and ageing. Her book "This Chair Rocks. A Manifesto Against Ageism" has just been released, and her Ted Talk received a standing ovation. She's onto something. This week on Inflection Point, she talks with Lauren about how she plans to end what she calls "the last acceptable prejudice."
