Is the world ending at 2012

Many people probably got they calender marked for the world ending at 2012 i don't but plenty of people do though.I really don't think about things like that happening cause it makes me scared cause i really don't want something like that happening cause i will only be 19 years old and im to young to die I don't think nobody should at that age but some do and also i really dont want to loose my friends and especially loose my family cause they are the best thing that ever happen to me and i love them but with everything happening with the earthquakes like that happening i really do think it might happen but i don't want to believe it.
