Nostalgia - running back into the womb

Nostalgia describes a longing for the past, often idealized.

The term was originally coined by Johannes Hofer, a medical student in 1678 (νόστος = nostos = returning home, άλγος = algos = pain/longing) roots, to refer to "the pain a sick person feels because he wishes to return to his native land, and fears never to see it again". This neologism was so successful that people forgot its origin. Moreover, its original meaning--referring to a serious medical disorder--has been lost as the word nostalgia entered everyday language.
