As Children, the peak-a-boo game was entertaining for a short period of time, decreasing in it's hilariousness due to repletion and predictability. Further in age, there were more sophisticated games that drew our attention, and the laughter increased in loudness and profoundness. We are beings interested in patterns, the older we get the more intriguing and satisfying complex patterns begin. Puzzles, riddles, mystery novels, the sciences, philosophy, ethics, predictability of human lives. But as we are start to learn about the world, a slipping on a banana peal becomes idiotic, pie in the face is equated with rudeness, and the peak-a-boo looses it's meaning because we know the person has not disappeared; from what I've experienced a learned individual it's simply harder to entertain.
Faerie Tales instruct children on being obedient, without questioning, borderline fascism undertones: I am an adult and therefore superior so do as I say. Yet, it's only when the viewer understands the concept questioning submission that the whole construct of the Faerie Tale becomes uncomfortable for was when we first experienced it in childhood we dare not question totalitarianism. In a mystery story, we are usually given clues, shady characters, possible motives, and incentive for us to work out the mystery, but if the mystery is solved out of the blue we feel cheated. Real life detectives often solve cases suddenly with a new found evidence, but we like to imagine patterns and reasoning behind it all.
The brain releases particular chemicals for particular emotions, and like drug addicts, when certain chemicals are used up frequently the receptors are worn out quickly. This results in addiction to emotions stemming from entertainment choices, and leaves the individual dependent on the same recurring form of pleasure derived from the medium of choice. There are consumers in the full sense of the word, dependent on emotions, sometimes pushing the limits of intake, going further and further into their addiction. Horror fans for instance might start loving Slasher Films, then gradually move up to Gore Films, then to Gorn, and to some extremes real violence captured on film. Genres like Comedy, Drama, Satire, Romance, can all be dangerous if taken addictively, similarly to the emotions music genres bring in. Neurologists have discovered depletion of dopamine derived from the extreme consumption of music. Furthermore, if one listens to sad music, major depression maladies can spring up, angry music can lead to hormonal imbalances, etc. Therefore, Neurologically speaking, the more one loves something, the less one enjoys it.
Some of the entertainers with longevity and acclaim often are the ones who are typecast into doing the repetitive act they're known for, and when they deflect are often met with negative results for the majority of the cases; like a loud angry yell in the peak-a-boo game would most likely send an infant from laughter to crying. Comedian Performers tend to be generally depressed individual because they wear out the chemicals for happiness, much like the drug ecstasy, whenever they perform at a club. Anger-driven performers tend to need spiritual wellness to be healed, or major pharmaceutical drugs. Intellectual Teachers often prefer silly humor to relieve the pressure from the amount of deep thinking intake. The duality of this, is also exemplified on the double life an entertainer lives, the necessity to put on an act with the audience as well as one for it's closes friends and family. Some entertainers can't handle this double pressure and choose one life over the other. Therefore, Neurologically speaking, the more one loves doing something the less joy one gets from it.
Growing up worshipping Capitalistic USA, one is often rewarded for being a fan or fanatic of a certain group of entertainment. Some subcultures even devote their entire lives dedicated to the adoration of a genre. However, from a psychological point of view, unbalanced individuals often recoil from change and cling to what they love most to the extreme in order to still get their fix. However, a well balanced individual needs to be aware of all kinds of entertainment, in order to be stable. As an entertainer myself, it has been extremely difficult to find said balance. If my work is too edgy, too unhinged, too unconventional, often people don't appreciate it because it's not the standard. And what sells is the predictable, what makes people comfortable, what tickles their fancy. However, to be a serious change in any sort of field, one has to break away from the cradle, and start walking. Discovering that big scary world where we'd have to work harder and harder to consume and perform great entertainment, and all it takes is one of us saying "No more peak-a-boo, here I am, deal with it".
