Nearing forty, Dr. Wendy Suzuki was at the pinnacle of her career, but despite her professional success, she was overweight, lonely, and tired. She knew that her life had to change. She started simply—by going to an exercise class. Eventually, she noticed an improvement in her memory, her energy levels, and her ability to work quickly and move from task to task easily. Her book Healthy Brain, Happy Life blends personal memoir and science narrative to show the connection between exercise, learning, memory, and cognitive abilities.
