Wind Through The Shutters

Nobody has ever thought himself to death.  The chief danger confronting us is not age.  It is laziness, sloth, routine, stupidity, -- forcing their way in like wind through the shutters, seeping into the cellar like swamp water.

-- Gilbert Arthur Highet (1906 - 1978), Scottish-American classicist, writer, and literary historian, The Immortal Profession: The Joys of Teaching and Learning (1976)
