Were all going to wake up Dec 22nd and live happily ever after. Dont let some spooks fool you. Besides how could we really know when the world is going to all of the sudden end because time is just a man made thing its probably around year 10 billion by now.
Well the world will end but not at one time & not at the same time for everybody. Our personal end of time is our death. That is imminent but we do have a say in how quickly it could come round by the way we live, respect or disrespect our body & the state of our nervous system & our mind. If I was you that is all I would be worrying about. That is all that I do. It makes life much simpler.
