Ashton Applewhite’s book (“This Chair Rocks: A Manifesto Against Aging”) is a wakeup call for a society obsessed with youth. The stigma of wrinkles. The stereotype of being feeble and forgetful. Ashton believes our worship of everything young creates a caste system where anybody over 50 is marginalized at best and shunned at worst. While you may not agree with everything Ashton says, she delivers a cherry bomb of an argument that people of any age can’t ignore.
