We’ve associated midlife with future decline and potential disability, a time when people begin to worry about being “over the hill.” The truth is, people between the ages of about 45 and 65 are at the top of the hill, with a life expectancy of nearly 80 years, and many of us will live even longer. Yet our thinking about “age” is stuck in a paradigm from the last century. Middlescence is a new life stage, filled with potential, vitality and purpose. Backed by quantitative research and the qualitative data collected over Barbara Waxman’s 30 years as a gerontologist, the Manifesto establishes that Middlescents are happier and more purpose-driven than almost any other demographic segment. She gives us tools and techniques to tap into those qualities so we can be filled with creativity, focus and potential. We can harness our leadership abilities to revolutionize our own lives and those of our family members, as well as revolutionizing our communities, workplaces, and the world.
