A hobby is an obsessive idea for something, an excessive taste or excessive hobby. The ethnic group is a group of people who belong to a same race and share the same language and culture. The etnomania is therefore a preference or preference for everything related to the culture and traditions of a region or nation.
etnomania is incorrectly written, and should be written as "Schizophrenia" being its meaning: Unusual behavior of human groups, manifested in the form of delirium, and euphoria estranbotica.
