The Importance of Bicycle and Pedestrian Infrastructure
"A top new argument: obesity. A stunning 34 percent of adult Americans are currently obese, another 32 percent clearly overweight, according to the Centers for Disease Control and Prevention. Excessive weight now causes more deaths than smoking.

What's the answer? Yes, diet. But more physical activity, too. We've allowed autos to carry us everywhere, even walkable distances of less than a mile (and even, in many cases, to the gym)! Our bodies fatten inexorably. One estimate of the country's annual medical bill for physical inactivity: $117 billion."
