This question comes from my bailiwick, transportation planning. It begins with this interesting article about mapping obesity rates and driving patterns:
The article acknowledges the limitations on what we can conclude from the results of the mapping (the refrain we often see here: correlation does not equal causation). But I do find the correlation itself pretty interesting. The article's comments seem thoughtful and civil (so far), with one commenter raising the issue of food environment/quality. This is on my mind as a new Wal-Mart Supercenter opens on Chicago's south side, to much fanfare for it's offering of "healthier" food choices to people living in urban food deserts.
I'm interested in exploring the connection between a paleo lifestyle and transportation choices/options. I am not personally a car owner, and choose active transportation most of the time: biking, walking, or transit (which also requires significant daily walking). Whenever I'm hauling a 24# pale of cat litter and another 20# of food home from the store on foot, I admit to a little smug "this is paleo exercise" self-satisfaction. But I live in a dense urban area with mass transit options--something much of America does not enjoy.
I'm curious if anyone here does factor transportation choice into their paleo lifestyles. Have you replaced driving your car for walking, for example? How about shopping on foot and hauling heavy groceries as part of a functional exercise/natural movement program? With acknowledgment of barriers like extreme distances, physical disability, jobs that require driving, etc., would you consider ditching the gym membership and making transportation one of your primary forms of healthy exercise?
