Taking the bus or train to work may be even healthier than walking, according to a new study published Sunday by the American Heart Association. “Bus/train commuters had even lower rates of diabetes, high blood pressure and overweight than the walkers or bikers,” according to a press release about the findings, which were presented at the AHA's Scientific Sessions 2015 meeting this weekend. The study, which was conducted in Japan, found that compared to drivers, public transport riders were 44 percent less likely to be overweight, 27 percent less likely to have high blood pressure and 34 percent less likely to have diabetes.
