Politicians are mastery of their own cultural gestures. Ground chief, instructs large machine operators. Scuba divers, alerts others to surroundings. American Indian use sign language as a bridge between disparate tribal language. Gestano, an universal sign language for human today. Koko, a gorilla who mastered Sign Language. Sheepdog, also a master of distinguishing gesture vs. behavior. Once basic gestures are mastered, one can tell the difference between gesture and behavior. Heck, even body behavior is a form of a language in itself. Association gets harder when going from physical realm into psychological; even harder when going into virtual abstraction.
