People living in sprawl and in nonwalkable places are more likely to be overweight, get less exercise, and spend less time walking
Also some people have physical abilities such that walking is not a valid lifestyle choice. For instance, two year olds.
I'm pro-walkable spaces. But it's not across the board superior to other arrangements.

Probably easier to push a child on a stroller through a walkable area than to put it in a car and drive to a location. Less time-consuming and better for the environment as well.
As well as walkable spaces being better for the elderly who can't legally drive and the handicapped who can't legally drive as well.
