Pushbike Peril
Low speed bicycle crashes can badly injure — or even kill — children if they fall onto the ends of the handlebars. So a team of engineers is redesigning the humble handlebar in a bid to make it safer.
Kristy Arbogast, a bioengineer at the Children’s Hospital of Philadelphia in Pennsylvania, began the project with her colleagues after a study of serious abdominal injuries in children in the past 30 years showed that more than a third were caused by bicycle accidents. "The task was to identify how the injuries occurred and come up with some countermeasures," she says.
By interviewing the children and their parents, Arbogast and her team were able tog reconstruct many of the accidents and identified a common mechanism responsible for serious injuries. They discovered that most occur when children hit an obstacle at a slow speed, causing them to topple over5. To maintain their balance they turn the handlebars t

The most damning thing that can be said about the world’s best-endowed and richest country is that it is not only not the leader in health status, but that it is so low in the ranks of the nations. The United States ranks 18th among nations of the world in male life expectancy at birth, 9th in female life expectancy at birth, and 12th in infant mortality. More importantly, huge variations are evident in health status in the United States from one place to the next and from one group to the next.
The forces that affect health can be divided into four groupings that lend themselves to analysis of all health problems. Clearly the largest group of forces resides in the person’s environment. Behavior, in part derived from experiences with the environment, is the next greatest force affecting health. Medical care services, treated as separate from other environmental factors because of the special interest we have in them, make a modest contribution to health status
A. a special aspect of an individual’s environment
B. a function of an individual’s behavior pattern
C. becoming less important as technology improves
D. too expensive for most people
