We have long been encouraged to think of old age as synonymous with deterioration. Yet, recent studies show that our decision-making skills improve as we age and our happiness levels peak in our eighties. What really happens to our brains as we get older? More of us are living into our eighties than ever before. In the changing mind, neuroscientist, psychologist and internationally-bestselling author Daniel Levitin invites us to dramatically shift our understanding of growing older, demonstrating its many cognitive benefits. He draws on cutting-edge research to challenge common and flawed beliefs, including assumptions around memory loss and the focus on lifespan instead of 'health span'. Levitin reveals the evolving power of the human brain from infancy to late adulthood. Distilling the findings from over 4000 papers, he explains the importance of personality traits, lifestyle, memory and community on ageing, offering actionable tips that we can all start now, at any age. Featuring compelling insights from individuals who have thrived far beyond the conventional age of retirement, this book offers realistic guidelines and practical cognitive enhancing tricks for everyone to follow during every decade of their life. This is a radical exploration of what we all can learn from those who age joyously.
