I don't really get why everyone stresses out on end of the world theories. If you're just going to live in fear of dieing what's the point of living? "Oh no there's a volcano that will cause a tsunami sometime in the next 1000 years oh noeess!!" "o god theres an asteroid that has a 25% chance of hitting us!!". Just live and enjoy life, as far as we know we only get one life to live, no one knows when the world will end and if you really want to get technical it probably won't end for a very long time. Call me an optimist but jeez people, the world has been around for billions of years, and now it's going to end in the next 10-100 years? Come on...
