Wearing a helmet, if you're a skier or snowboarder, reduces your risk of having a head injury by 60 percent.

The study showed that head injuries are very common. One in every six injuries in the study was a head injury.

It seems like it is a smart thing to wear a helmet if you ski or snowboard. Even if you're not aiming for Olympic gold, but you are skiing or snowboarding, just for fun or pleasure.

Do as the Olympians do. Wear a helmet, even if you're not an elite skier or snowboarder - especially if you're not.

I believe helmet use should be promoted strongly, and ski resorts could make helmets available for free to skiers and snowboarders when they buy their lift tickets.
