Off topic, but something you might find interesting.  I have been watching a film on Amazon Prime about an elderly man in Brazil. He was  from a village in Ukraine during the Nazi era, sent to Germany to work as a young man and after the war migrated to Brazil.  In his 90's he is given a trip back to Ukraine to visit his home and to see his family there.  A beautiful documentary, very well made.   In Portuguese and Ukrainian with subtitles.   I highly recommend it.
