The land we live, we have much to discover it is a land of mysteries if we are to say correctly. There are plenty of places in the world where the sun does not rise or tend to rise late. At these places, nights stay for much longer than excepted and the sun does not rise. Earth holds many such places where there is no light at all. All these seem like a land of fairies and mysticism. Our routine revolves around 24 hours a day, with around 12 hours a day. With around twelve hours of sunlight and the remaining hours are nighttime.
