We're keep saying “better safe than sorry” but after all only few of us truly taking necessary precautions for most of unfortunate events. Many people would probably think why something like that should even concern them in the first place. The answer is obvious for the same reason you keep a spare wheel in your car. You never know where or when or how a possible accident might happen no matter how carefully you prepared for an emergency no one can really predict the future. However, by making a detailed plan of your behavior in extreme situations you will be able to come up with an appropriate strategy of making right decisions which will possibly even save your or someone's life.
