Want to add more years to your life? Perhaps leave the car at home on your commute.
According to researchers at the University of Otago in New Zealand, those who biked to work saw a 13 percent reduction in early death rates compared to those who got behind the wheel every day. No difference was seen for walkers or public transit riders.
The results build on similar findings by other teams in the UK and Denmark. A cyclist's risk of heart attack dropped by at least 11 percent in the Danish study.
Census data shows that only 0.6 percent of Americans bike to work. Of the US bikers, most are city dwellers, aged between 16 and 24.
