What can’t be cured must be endured.
This phrase is the title of a 50s era Greek movie. It comes from a post-war time in Greece (which was then followed by a civil war), when poverty was extreme for some, and the memory of starvation during the Nazi occupation was perhaps still fresh. The English translation catches some of the meaning, but the Greek seems to mean something more like “have fun, since poverty leaves us nothing else”. See also: Zorba.
