Summary of: Successful Aging: A Neuroscientist Explores the Power and Potential of Our Lives
By: Daniel J. Levitin


In the book summary of ‘Successful Aging,’ the author Daniel J. Levitin takes us on a journey through the various aspects of aging, breaking down common misconceptions and offering insight into the positive elements of growing older. By exploring the neurological shifts that occur in our brains as we age, Levitin demonstrates how we can embrace the unique strengths that come with aging in areas such as practical intelligence, perceptual completion, and improved decision-making abilities. The summary also delves into busting myths surrounding memory and cognitive decline, ultimately suggesting that growing older isn’t just about losing abilities, but growing and developing in new ways as well.

The Upside of Aging

Aging comes with its challenges, but it also brings positive changes that should be celebrated. While cognitive function may slow down, there is increased emotional balance and a greater tendency towards forgiveness, compassion, and practical intelligence. Aging brains are also better at filling in gaps in perception, making life easier. Growing older means accepting limitations but also enjoying the positives that come with it.

Debunking the myths of aging

The aging brain doesn’t just decline, and there are two other aging myths that need to be debunked. Firstly, memory is way more complicated than it is thought to be. Research shows that people of all ages experience short-term memory lapses, but when older people experience it, they have been primed to believe it’s the result of cognitive decline. Older brains perform better in making judgments and decisions based on pattern recognition. This improves their memory function, makes them better at zooming out, and taking a bird’s-eye view of things. Secondly, the belief that older adults can’t achieve much if they start a new hobby or skill is untrue. For example, Anna Mary Robertson didn’t start painting until she was 75, and the founder of KFC, Harland Sanders, started his business at the age of 62.

The Impact of Nurturing in Childhood

The way we age is impacted by many factors, including genetics, environment, and opportunities, but one of the most significant influences is our childhood. Nurturing in the early years affects us on a chemical level, impacting our stress response and immune system. Studies have shown that being nurtured leads to fewer stress hormones and a stronger immune system throughout our lives. The study of baby rhesus monkeys conducted by Harry Harlow demonstrated the powerful impact of nurturing on our desire for contact and comfort. While we can’t change our upbringing, we can address the impact of our childhood experiences on our brains through therapy, thanks to the phenomenon of neuroplasticity.

Personality and Health

Our personalities play a significant role in determining our health span, but the good news is that neuroplasticity allows us to change our personalities throughout our lives. Our environment and opportunities also contribute to our personality, but our brains’ neurochemistry has a major impact on our interpretation, reaction, and engagement with the world. Based on research, lower childhood conscientiousness is associated with worse lipid profiles, obesity, and physiological dysregulation. To extend our health span, we need to adopt the COACH principle, which means embracing challenge, maintaining openness, cultivating conscientiousness, and fostering positive relationships.

COACH Principles for successful aging

The COACH principle, comprising five important aspects namely curiosity, openness, associations, conscientiousness, and healthy practices, is essential to healthy aging. People who embrace new experiences are statistically more likely to perform well in life outcomes and have lower risk of heart disease, Alzheimer’s, and diabetes. The fixed mindset and growth mindset concepts introduced by Carol Dweck are important to understand the difference between people like Luca and Fatima. Fatima’s growth mindset, openness, and connections with others contribute significantly to her chances of aging successfully.
