In the district Cote-d'Or (France) legends about werewolves have a strange detail: it is believed that a person can only be a werewolf certain period of time, usually ten or seven years. Where did these numbers? Apparently, we'll never know. Although most of the stories related to lycanthropy, French or German origin, there are plenty of perfectly credible stories about werewolves and likoreksii (condition when a person suddenly begins to imagine himself as a wolf and feel ravenous appetite, together with other terrible symptoms) occurring in countries such as For example, Austria and Russia. However, among the Slavic peoples of legends about werewolves are very closely intertwined with the legends about vampires.
