Q-tips can cause more problems than they solve

Swabbing the ear with a Q-tip can disrupt the ear wax that naturally protects the ear from dirt and bacteria.

We may be using Q-tips in our ears—even when we shouldn't—because they can stimulate pleasure nerves

People continue to use Q-tips inside their ears even though we know it's risky. Some clinicians suggest that beyond the desire to get water out, this may be because the nerve bundle called the vagus nerve, which spans from the brain to the large intestine, can be stimulated that way, causing a pleasurable sensation in other body parts including the heart, belly, or genitals.

Why pickles became a thing

Pickles began in Mesopotamia around 2400 BCE as a way to preserve vegetables amid heat (and spoilage). They spread through Egypt, Greece, and Rome, where Julius Caesar reportedly fed pickles to his soldiers, and brining was treated as a culinary art. The technique is broadly useful, as salt and water can extend the shelf life and deepen flavor for almost anything.

Kids saying "67" and then erupting in laughter may have been popularized by social media, but childhood rhymes, songs, and jokes that confuse adults have always existed. Iona and Peter Opie studied the phenomena, publishing numerous books on the topic from the 1950s through the 1980s.

Before 1920, a single baseball was used throughout a game

During the Deadball Era, pitchers doctored a baseball with spit, nail files, and licorice for a competitive edge, leading to discolored, mangled, and lopsided baseballs by the game's end. This concluded in 1920 when Cleveland Indians star shortstop Ray Chapman was hit in the head by a ball too dirty to see and died. The rules were changed to require an umpire to replace a dirty baseball and outlawed the spitball.

Improved 19th-century sanitation meant kids encountered polio later, with worse results

Almost all children likely used to contract poliovirus, but scientists suggest that when infants encountered it very early in life—due to poorer conditions and hygiene—they still had some maternal protection from pregnancy or through breastmilk, so the symptoms were more flu-like.
