If you spend your life worrying when you are going to die, then you will never truly live your life as if you were going to live. If we all die in 2012, we all die, there is no way to prevent this occurrence. However, I do not believe that we will all indeed perish at the hands of some higher power, or the sun's rays, or some prophecy, or what have you. I decide to live my life as if I wasn't aware of this impending doom because it doesn't matter in the long run.
