Most people probably don't think too much about health issues when they decide on a place to live. Many assume that exercise, diet, and habits such as smoking depend more on personal initiative and less on choice of neighborhood. To a degree, they are right. If you are determined to live a healthy lifestyle, you can do it anywhere. The reverse is also true. Yet what is true for an individual is not necessarily true for a community. Aspects of the built environment make it easier or harder to maintain health. An environment where one can more easily get around on foot or on a bicycle will help a family to be less sedentary. That daily trip, on foot, to the park, elementary school, or store may seem unimportant. Yet it may make the difference, in the long run, as to whether a family member becomes overweight, which in turn contributes to myriad health problems.
