Jewaun Smith, a 9-year-old boy from Chicago, is lucky to be alive. A scrape on his left knee that he picked up riding his bike last October turned into a runaway infection that spread in a matter of days through the rest of his body, leaving his lungs riddled with holes. Jewaun managed to survive, but what worries doctors most about his near-death experience is that it's not an isolated case. The bacteria that infected his knee has become resistant to the most common antibiotics and is on the march across the U.S. It has spread...
When motorcyclists wear helmets, they are less likely to die if they crash--no one disputes that. But should helmets be mandatory? The question came to the fore last week after Pittsburgh Steelers quarterback Ben Roethlisberger, a helmet opponent, crashed his bike, breaking his jaw. Pennsylvania didn't require him to wear a helmet; 30 states have rolled back their helmet laws since the 1960s, and more may follow.

The subjects, men in their 30s and 40s, experienced no blood flow to the penis as soon as they straddled the protruding portion of a bike saddle. "What you're worried about is that the pressure will cause what we call endothelial injury, which is a harbinger of the beginning of localized atherosclerosis," says Goldstein. "Over time, that can develop into permanent impotence...
...bike lovers don't have to abandon cycling altogether. Instead, Goldstein suggests they choose a bike with a noseless seat that allows riders to bear their weight on their sit bones, just as they do when sitting straight on a chair. Goldstein concedes that the nose helps racing cyclists steer and navigate turns more easily and that some may fear looking "wussy" with a wider seat. But, he says, riders have to weigh health risks against speed or style...
