Sanity is an idea as young as modern mental hygiene, or as the kids say these days "momenhi". No, that last bit is obviously made up, but then, so is every term we use to describe the inner workings of the mind. Since the early endeavors of Carl Jung and Sigmund Freud, personality disorders, neuroses and other maladies of the mind made the leap from "imbalances of the humours" and "demonic possession" to medical conditions. This required new terms! Maybe back in the days of Jung, "id" "ego" and "superego" were all hip terms, like "PWN" or "FOMO."

Today, we have physicians to diagnose the specifics of mental problems, but for the rest of us, the shorthand remains. Words like "lunatic" used to be de rigueur when colorfully describing insanity. The term came from the suggestion that bouts of mental illness came about due to the phases of the moon ("luna"). Today, that's too many syllables, as is "crazy." Rather, we use shorthand for the shorthand. Cray, or if we reference someone truly nuts, cray-cray.

Our standards for what constitutes crazy have also changed significantly. Now, some behaviors are considered eccentric, but would have been deemed crazy just 10 years ago. Conversely, other acts which would have been fine a decade ago are today considered completely nuts! Are you cray-cray? Time to take this quiz and find out!
