Marcus Hiles encourages tenants to reside in locations with footpaths, explaining that those who take advantage of even mild exercising on the paths enjoy healthier lives. A 2008 study done by the American Journal of Preventive Medicine expands on this idea, suggesting that people living near park areas tend to have a lower risk of obesity. A 2010 study by the journal Social Science and Medicine found that those who reside near large amounts of green space were more relaxed than those who spent less time outdoors. Hiles, a strong believer in community building, says that in addition to their ability to help lower energy costs and foster active lifestyles, trails also promote a sense of closeness among communities, with pathways encouraging spontaneous meetings and interactions. Environmental, practical and fun: a series of walking trails are an amenity no housing development should be without.
