When the world is on the brick of destruction, everything and everyone is turned upside down and twisted inside out, nothing is quite the same anymore. It messes with your mind to the point that you no longer trust your own thoughts, because rules of the humanity has changed into a lawless anarchy. As these developments occur, the more primal and animalistic you become and your appearance slowly deteriorates, almost looking as if you are a zombie. This is my before and after pictures, to show the effects the apocalypse. My before picture I took in my room where there is good lighting and then edited to appear more presentable and my after picture I took later today after running from the infected in the woods.
