I watched the program ” End day” in Discovery channel. This story was incredible .what if the world is ended, how can we do that? the answer is nothing. as scary as nothing compared to this story. they said 4 parts of senarios what will it happened some day. At first, all over the city is supposed to cover with huge flood as tsunami. Second, Meteor collapsed the earth. Third, viruses spread it out as if we’ve seen before the movie from “Out break”. Finally, they are supposed to say about “Black hole” . I can’t imgine what will it be is true or not. but I just would like to say that we do your best in present.
