In his book "A Walk in the Woods," Bill Bryson highlights the stark contrast between the physical activity of hikers on the Appalachian Trail and the average American's walking habits. Bryson notes that while he and his companion Katz are able to walk greater distances in just twenty minutes, most Americans rely heavily on cars for their journeys, rendering them less active. This reliance has led to a dramatic decrease in walking, with many Americans only accumulating an average of 1.4 miles of walking per week.

The statistics Bryson presents are striking; people now often engage in minimal physical activity, breaking down walking to short spurts associated with errands and commuting. This shift towards a more sedentary lifestyle reflects broader societal trends where convenience takes precedence over exercise. Bryson's observations encourage readers to think critically about their own habits and the implications of a lifestyle that prioritizes driving over walking.
