I am going to make a very shocking announcement here. I actually believe... Heh heh, sorry I just could not finish that sentence with a straight face. No,I do not believe this or any other doomsday theory. And even if I did, frankly I wouldn't worry about it. Any catastrophe that could possibly end all life as we know it on this planet would likely be out of our control and completely unpredictable, so as far as I'm concerned I'll cross that bridge when I come to it. For now, life as usual.
