Worried that humanity is coming to an end on Friday? Well, everyone around the world is. Since the last couple of days, buzz is high that the world would end, as per Mayan prophecy, on 21 December, 2012. On the other hand, another report says that there would be a total blackout throughout the world from 21 to 25 December because of change of planetary positions. Whatever be it…the situation certainly seems to be a little grim. While some people are scared, many brush this report off as another petty joke.
