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