Legends are tales that, because of the tie to a historical event or location, are believable, though not necessarily believed. Legends usually involve heroic characters or fantastic places and often encompass the spiritual beliefs of the culture in which they originate.
Though most of them are proved untrue, some people seem to believe them and thus taking advantage of this, businessmen, politicians etc target on legends to attract the general public.
Legends provide an outlet for people in a number of different ways. For the person who does not believe a legend he has received, participating in the distribution of it will fulfill another need: breaking boredom and providing a social outlet. For others, believing in a particular legend is an emotional response. Legends can feed into the fears, anxieties, and biases a person may feel toward the subject matter or society in general thus providing them with emotional gratification.
Legends, though must be respected because their value lies in the message it conveys and what it teaches rather than what the story says.
