Analogy

The world is like a smorgasbord. Food can be categorized into many groups in order to make it unique from another style of food. Examples include spices, poultry, salads, burgers etc. Similarly a country can be distinguished from another by population, language, ethnicity etc. Any place on earth is unique from another. A person will have a different "taste" of the country. Some food can be bad for health, and some considered nutritious. Countries/places can be wealthy or poor. Poor countries and bad food are not good for human beings because they will not live a healthy and happy life.
