Off on a tangent here. Maybe cutting is a symptom of a society where the "acceptable risk" bar is rising. That is, people will go up to the line of immenent death, testing the limits. But people are harder to kill these days. Doctors are getting better and better at bringing people back from the brink. Thanks to GPS, we also have the ability to extract people from the most remote and compromising situations. Thanks to antibiotics, a simple cut rarely kills.
We have heavy cross-checking in hockey resulting in more serious injuries (thanks to better protection, ironically). This was predicted by an instructor of mine over ten years who specialized in "acceptable risk". Think about it. Before the heavy padding and the helmets, those guys on the ice were a little more careful how they hit their buddy in to the boards.
We have extreme sports.
Where once mount Everest was the ultimate human challenge, we have had the blind and the paraplegic safely make it to the top.
