I've been trying to diagnose a phenomenon that I noticed in myself for a few months. I don't know what to call it, but I'll go with "Involuntary Chants." That might not be a fitting name, but I'll describe it using two instances.
"The patient dog eats the fattest bone". Nearly every child who grew up in Nigeria knows that quote; it was told and repeated to us everywhere: at home, in schools, in markets, and in religious places.
