The brain-changing benefits of exercise is the area of Wendy Suzuki’s research, the topic of her 2017 TED Talk, and of her book Healthy Brain, Happy Life: A Personal Program to Activate Your Brain and Do Everything Better. It’s also deeply personal. Suzuki’s late father was diagnosed with Alzheimer’s in 2009, and her daily commitment to exercise is an important element of a strategy, which also includes a healthy diet and proper sleep, to do everything she can to stave off the disease in her own life.
