A more reason why people who live in NYC put up with living in NYC: Quite frankly, living in the suburbs can make you sick. Or at least that's the implication from a study the Rand Corporation did. The study found that "suburban sprawl is linked to the incidence of many chronic health ailments," such as high blood pressure, arthritis, headaches and breathing difficulties. Roland Sturm, a Rand economist, said, "This is the first study that analyzes suburban sprawl and a broad range of chronic health conditions, We know from previous studies that suburban sprawl reduces the time people spend walking and increases the time they spend sitting in cars, and that is associated with higher obesity rates. This probably plays an important role in the health effects we observe.” Word - think about those huge Big Gulps people get during their commutes. People don't need 64 ounces of soda for the ride home; we saw Super Size Me. Other fun findings:

- The findings suggest that an adult who lives in a more sprawling city such as Atlanta willhave a health profile similar to someone four years older — but otherwise similar — who lives in a more compact city such as Seattle, according to researchers.
- The study found no link between suburban sprawl and a greater incidence of mental health problems. - The findings appear in the October edition of the journal Public Health, in an article titled: “Suburban sprawl and physical and mental health.”

Gothamist would like to thank the Rand Corp. doing this study, because it's just another reason why we love our teeming city, full of crazy expensive rents, crazy people, expensive habits and anything else you could possibly want, so much.
