country

The concept of happiness is well known as in philosophy, as psychology, as etic. Happiness is looked as constant humans psychological state, as moment euphoria, gleam. Yesterday I watched documental film, where the happiness constant was analyzed in country, nation meaning.

By this, I would like to clarify how to write countries, languages and currencies in short form. Especially it is important when working in international projects or with software components where these standards are used. For example, how to you think what is 3 digit code for country Latvia? – LAT or LAV? Correct answer is LAV, because LAT is language short form.
