One of the most creepy places to visit is Candido Godoi - a town located in the south of Brazil. The twin birthrate in this place is 18 times higher than the world average. The specific cause of this remains unknown.However, there have been speculations that Nazi doctor Josef Mengele caused this through his experiments. He performed experiments on Auschwitz prisoners so that he could find a way to rapidly expand the Aryan population in Germany. After the war, he fled to South America and continued with his experiments.Historians deny this. They attribute the town’s high twin rate to toxic waste or inbreeding.
