Hopefully, I just made you say underwear.
Even if I didn't, consider this fun fact courtesy of a medieval historian:
In the 13th century, more people moved to urban cities. Because of that, the use of underwear increased, since developing cities frowned upon the peasant tendency to wear nothing under a smock. With an increase in underwear came an increase in rags made out of worn-down underwear.
And, with an increase in rags came an expanded supply of material used by papermakers to make books.
With more material came more books. More books brought more literacy.
So thank your underwear for furthering Western culture.
Just don't do it out loud.
