And for the more unusual

Life goes on, no matter what, and being prepared and quickly accepting any situation whether it is the 'usual or the unusual suspects' will put you further ahead of the curve. Getting ahead of the rest of the crowd usually means you are ahead in the survival game. All that is usually required is just a modicum of common sense and the ability to think for yourself rather than succumbing to the mass hysteria of the crowd. The mass hysteria today is usually provided by the mass media. Just learn to filter out the news media rubbish and take on board what is important for yourself, your family and your community.
