The purpose of science and statistics is to make us aware of what kind of risks we are taking, so that we in turn can make informed choices.
I am glad someone on here likes using their brain. It is true, science can't tell me whether or not I will die from oropharyngeal cancer, but it sure as hell has the potential to tell me how likely I am to die from oropharyngeal cancer. As an avid backcountry skier, I regularly put myself in situations that most people would consider too risky. However, I don't do so blindly. I don't say to myself, "Well, I know someone who skied yesterday and they didn't die so I will be fine". I gather as much information as possible about the different variables, recent weather, predicted weather, snowpack conditions, terrain, routefinding, abilities of those in my party, etc. THEN, I use this information to weigh whether skiing in a particular spot on a particular day in particular conditions is an acceptable level of risk to me. Yes, I might die in an avalanche, but if I am constantly seeking out information to inform my decisions, I doubt it.
