One of the best books I read when I was young was Heinlein's Stranger in a Strange Land (Biblical phrase) which has been referenced frequently in popular music. 

Well I am no longer young and I feel as if I am a stranger in a strange land when, for example, I get on the subway in Long Island City along with the throng transferring from the Brooklyn train which parades by sporting their art, tats and sleeves on their arms, legs, faces, chests, backs and who knows where else. 

It is not for me to pass judgement on this generational statement, but I do notice and wonder.
