"One fascinating feature of remembering is how a cue from the external world can cause us to suddenly remember something from years ago. For example, returning to where you once lived or went to school may bring back memories of events experienced long ago. Sights, sounds, and smells can all trigger recall of long dormant events. These experiences point to the critical nature of retrieval in remembering."

debbyski, your asterisked comment has exactly described the theme of Marcel Proust's novel "À la recherche du temps perdu"—known in English as "Swann's Way," "In Search of Lost Time and Remembrance of Things Past."

From the Novel: "memories of, the French town Combray. Inspired by the "gusts of memory"
that rise up within him as he dips a Madeleine into hot tea"

A Madeleine is a small, rich cake, baked in a shell-shaped mold.
