A long time ago, psychologists believed that intelligence and IQ were fixed at birth. In this book, Hurley digs deeper by meeting with field specialists and researchers, and he becomes a human guinea pig. He improves his fluid intelligence over time by doing a bunch of different stimulating activities. The book goes over practical findings that sharpen the minds of children, young adults, seniors, and those with cognitive challenges. It was interesting to read and it provides tips on what you can do to improve your life too.
