Anatomy of Laughter

Laughter is a physical reaction in humans and some species of primate, consisting typically of rhythmical, often audible contractions of the diaphragm and other parts of the respiratory system. – Wikipedia

The above definition speaks more about us than about laughter. If we consider laughter as “audible contradictions”, then something must be wrong with the Kingdom.

Kingdom is serious
Laughter was always considered threatening to serious rules, rulers and regulations, designed to disseminate fear and trembling among citizens. First victim of laughter was Socrates, who was ironically asked to choose the way to be punished. After Socrates, history presents us with a continuous line of exiled, poisoned and punished jesters who paid dearly for provoking audible contradictions accompanied by watery fluid.

Laughter cannot be explained without tears, profoundly explained by the Dictionary (below)

Tears
“A drop of the saline, watery fluid continually secreted by the lacrimal glands between the surface of the eye and the eyelid, serving to moisten and lubricate these parts and keep them clear of foreign particles.” – Dictionary & Thesaurus
