Ambiguous Warning Shouts
Look out! Watch out! Heads up! What are you supposed to do when someone shouts one of these at you? Most people hunch over slightly and feebly raise their hands close to their head. Another common reaction is to turn directly towards the source of the warning, which, if this is also the source of the impending danger, is about the worst thing you could do. I propose instead a series six of generally accepted warning shouts: Stop! Run! Duck! Jump! Step left! Step right! Doesn’t that seem much more likely to save your life than HEADS UP? Even if you don’t know your left from your right, you still have a 50/50 chance, which I would say is better odds than you get from WATCH OUT!
