it would throw off the crazy unexpectedness of it all. There would be no guinness book of world records cause most people would see they were going to die. It would be full of people in iceland with 8 ft long beards...i mean not like anyone reads guinness books anyways...but thats another topic.

Also we'd all spend our whole life counting down the seconds (yes we would) and thinking up ways to avoid death. Look, were human we dont want to die we dont want to see the end of something like life.
