Can The Suburbs Make You Thin?
It appears that having a large backyard to romp around in the early years has lifelong health benefits. So, a larger 'footprint' in the way of low density living works out to a smaller 'footprint' all the rest of your days in terms of how much it will take to support your appetite.
"Preliminary data from the Flinders University Achieving a Healthy Home Environment study, which surveyed the homes and lifestyles of 280 southern suburbs families, found the size and set-up of homes contributed largely to how fit and healthy young children were."
