To those of you who say it won’t happen to you, it will.  Trust me.  I have been there.  Whether it’s an earthquake or a shipwreck, being without power and heat, not being able to buy food at the supermarket, or anything else, it’s the same situation.  We all have to be prepared to live on our own.  Stock up food and water so you aren’t one of the people mobbing the stores, or so you can feed yourself while waiting for the rescuers.  Always be prepared.
