I remember, when I first took skiing we didn't wear helmets. Mind you, we were wearing wooden skis and strap bindings in those days, as well as lace-up boots. That was a few years ago, in the Maritimes.
As Ash pointed out, it's the sporting body that has made changes, for example in volleyball, to make sure we're seeing fewer injuries. How much pressure should we be placing on those sporting bodies to actually step up in this avenue and make those changes?
