FutureLawyer points to the best age verification test of all time. Years ago, a noted mystery writer who reached major success and was suddenly surrounded by young and beautiful women, had a knowledge compatibility test. He'd ask prospective dates, "Who is Whittaker Chambers?"
If he used that question today, he'd be a very lonely man. We can find ourselves preserving terms from our childhood or even our parents' childhoods. When I was young, I was told to "Put the milk in the icebox" even though we had a refrigerator. My parents had grown up with iceboxes cooled by blocks of ice. In those days, the iceman did indeed cometh.
I still occasionally use that term. It has a flair.
