I dont even care anymore. 2012, 2025, whatever. The world is going to end when some jackass madman comes in to power in some unstable region that has nuclear capabilities and some ICBMs on hand, launches one to let his people see his strength, trips our systems and causes our SSBNs to launch Trident II D5 Missiles carrying 12 warheads each as a retaliatory measure. Other countries will freak, everyone blows up and dies. That's a more realistic scenario than some stupid Mayan calendar predicting Armageddon, an asteroid hitting us or gremlins taking a bath and running rampant.
Personally, my world ends if HR2811 passes.
