Michaeleen Doucleff reports: "Hospital admissions because of bike injuries more than doubled between 1998 and 2013, doctors reported Tuesday in JAMA, the journal of the American Medical Association. And the rise was the biggest with bikers ages 45 and over."

"Another study, published last month in the Morbidity and Mortality Weekly Report, found a similar trend with bicycle deaths: While the death rate among child cyclists has plummeted in the past four decades, the mortality rate among cyclists ages 35 to 54 has tripled."

The article goes on to examine a pair of viewpoints about how to mitigate the public health risk presented by riding a bike. Dr. Benjamin Breyer, who led the study published in JAMA recommends helmets and bike lights. Jason Vargo, however, who studies urban planning at the University of Wisconsin, Madison and led the second study cited above, "says society also needs to change the definition of what a road is to implicitly include bikers."
