After a bicycle accident forced her think differently about her body and the role of movement in her life, Collins (creative writing, Central Connecticut State U.), an athlete, was inspired to explore the sedentary lifestyle of the majority of Americans, and the forces that create it, including historical factors like farming and the Industrial Revolution. She discusses other species, the walking trails of prehistoric people, factory workers, Olympic athletes, government efforts to get people to exercise, church-sponsored exercise, effects on the brain, how small shifts can bring physical movement back into people's lives, and the two most immobile populations: Hispanics and African Americans.
