** On a related matter, ''any'' trope involving a [[Phone Booth]] is pretty much dead and is only likely to appear in works set between 1930 and 1975, when phone booths were commonplace.

* [[Food Pills]] (a complete meal—usually offered in a variety of perfectly convincing flavors—in a tiny capsule) were all the rage for the well-stocked future of the Golden Age of Science Fiction, but today's future food is more food-like. If there ''is'' concentrated food—such as the "protein pastes" that may be [[Food Pills]]' spiritual descendants—it tends to taste nasty. The change is no doubt due to the growth of the health-and-exercise industry and the subsequent general awareness that the human body needs considerably more than just a few milligrams of vitamins per day.

* The use of blood typing to exclude suspects in a mystery story now only appears in rare period pieces, as evidence in resurrected old cases, and as preliminary evidence in the ''very'' few stories that have DNA tests realistically take time to get back.

** Inversely, as widespread DNA testing gets older it's increasingly unlikely that someone would not only be exonerated post-conviction by DNA testing ''and'' the relevant parties (at least the falsely convicted and the real criminal) still be alive, let alone have any trail left.

* The use of smelling salts to revive a [[Fainting|woman who's fainted]]—more precisely, the virtual omnipresence of smelling salts in every home. Judging by any number of classic movies from the [[Golden Age of Hollywood]], you were more likely to find smelling salts in a random medicine cabinet than you were to find aspirin. As [[Fainting]] itself became a [[Dead Horse Trope]] if not a Forgotten Trope itself, its quick and easy countermeasure vanished from the trope pool as well.
