If you are reading this then you have access to the World Wide Web so listen up. We are the last few of the human race that has survived just like the Mayan said would happen. As you know either a black hole, the Sun blew up, Planet X hit us, zombies has returned, Jesus is here or the Internet isn’t working and civilization is on the edge of dying completely.
So the first thing you got to remember is to find a place to stay. Remember the most important thing to find is to get access to the World Wide Web so you can post online that you survived. The second thing is to want to make sure you take as many photos as you can of any weapons, any food caches you have online so people know it is safe to come to you.
