Thus demonstrating that it's very EASY to argue from a life/death standpoint. Which is fine...perfectly legitimate argument. "Cost effectiveness", however, is NOT.
My father's neighbor actually got on Rescue 911 for his accident. 20 years experience riding, locked up on gravel, flew into a ravine, snapped a 6-inch sapling in half with his leg, left most of his calf in another tree. What saved his life was...his leather riding gear, actually. Aside from where his leg intersected the tree, he didn't have a mark on him...but his medical bills were insane nonetheless. He's still in physical therapy 10 years later.
Another guy...managed to decapitate himself on a stop sign (tough to do, road signs aren't exactly sharp). His medical bills were dirt cheap.
