When I was a kid, adults treated "knowing what to do if you're on fire" as an essential life skill to practice and review. What is the history behind "stop, drop, and roll"? Why did this very specific emergency get so much emphasis?
Responses to more common hazards weren't addressed to nearly the same degree, if at all. Off the top of my head: pressure and elevation to control bleeding; Heimlich maneuver if choking; don't swim out to a drowning person, throw them something instead; lightning position; don't pull out impaled objects; don't run if being chased by an aggressive or overexcited dog. With the possible exception of the Heimlich maneuver, I don't think those require any more cognitive or physical ability than stop-drop-and-roll. Those situations all have to be at least as common and can be as serious as being on fire. What was (is?) the deal with stop drop and roll?
