Yes, people can survive without beer, but the enjoyment of a sporting event is enhanced by having a drink or two. (Don't get it twisted, though, just a few. Drunken assholes in the stands are assholes.)

I think you'd want to leave it on at ski resorts. If you crash into a tree going downhill it is usually a serious event. I don't know how sensitive the threshold is, however, so it probably needs some tuning around falling down versus serious crash.
