Ever wonder why you don't walk into walls? How you decide if you can drive through a snowstorm? How high you are willing to climb up a ladder to change a lightbulb? Physical intelligence is inherent in all of us—and always in problem-solving mode. Through the prisms of behavioral neurology, Scott Grafton brilliantly accounts for the design and workings of the action-oriented brain in synchronicity with the body. Drawing on insights gleaned by engineers who have learned to emulate the sophisticated solutions Mother Nature has created for managing complex behavior, Grafton also demonstrates the relevance of physical intelligence with examples that each of us might face—whether the situation is mundane or extreme.
