> Wearing a helmet increases your chance of death on a bike according to the statistics I've heard that too. If it's true, could the causality be the other way? As in, people wear a helmet when the chance of accidents is bigger. When I road bike on open roads it's both fast and higher chance of accidents, so I wear a helmet. Same with downhill cycling. But when using a city bike, I bike slow in the inner city, and don't have a helmet.
