Tourism

           Tourism can be domestic or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Today, tourism is a major source of income for many countries, and affects the economy of both the source and host countries, in some cases being of vital importance
            Travel outside a person's local area for leisure was largely confined to wealthy classes, who at times traveled to distant parts of the world, to see great buildings and works of art, learn new languages, experience new cultures, and to taste different cuisines. As early as Shulgi, however, kings praised themselves for protecting roads and building way stations for travelers.
