Aquarius, I was also thinking about this very subject today. Yes I do live each day as if it was my last and enjoy it to the full. Be it doomsday on 21 Dec 2012 or getting killed in a car crash, anything can happen at any time in the future and our life's are so fragile. I do read read with interest regarding Polar shift, Nibiru, Galactic plane re -alignment, Mayan calendar etc and they all do seem to point to something happening, but as to what can only be speculation on our part, maybe it will be like the Millenium bug for example with a lot of theories before and nothing of real note afterwards, then again it might be the worst case senario's. Keep informed and enjoy is all I can suggest to all. Hope this helps ease you alittle!
