This book uses research from developmental neuroscience and the psychology of individual differences to show that sixty-plus years is a unique developmental stage that, like infancy or adolescence, has its own demands and distinct advantages. Levitin looks at the science behind what we all can learn from those who age joyously, as well as how to adapt our culture to take full advantage of older people's wisdom and experience. Throughout his exploration of what aging really means, Levitin reveals resilience strategies and practical, cognitive enhancing tricks everyone should do as they age. This is a powerful new approach to how readers think about our final decades, and it will revolutionize the way we plan for old age as individuals, family members, and citizens within a society where the average life expectancy continues to rise.
