Wearing a helmet for sport cycling is obviously a good idea. The epidemiological evidence that they are useful for everyday cycling is far more limited, and despite the online flame wars, helmet wearing is largely cultural.
Public skating rink where small children wear helmets, but vast majority of teenagers and adults do not.
