Well, here are some illustrations of my words, - to do my analyse I’ve choosen the 1st part of “chippy_5.wmv” video clip. Let’s examine YN behavior during this short video episode, using “step-by-step” mode and let’s try to find something unusual in her behavior.
The first one thing that can be immediately observed in this movie is that YN copies the positions, the gestures and the actions of someone, who stands behind the cameraman (just check her eyes). As you understand – this is a woman (the most usual these women-“instructors” also are 100% naked during the shooting of the film, to encourage the young girls). There is also a man behind the filming camera, who gives her orders. Without them YN does not know, that to do – check the time “00:20” – this is a moment, then she does not understand, that to do, - she receives an order from the man, that contradicts with the indications of the woman-“instructor” (finally YN follows the indications of “instructor”

and she stands in indecision. It does not mean, however, that she’s mentally ill (or she’s oligophrene), but it manifests with evidence, that she does not know, what to do during shooting, and she needs in someone, who can help her anytime – she just copies his/her actions and executes orders. At the same time – even the 100% null in porno-business normal 18 y.o. girl can easily learn all these well-known positions and the order of theirs execution. There are also special trainings before the shooting, that allow to learn these positions well. In case of YN, we have an illustration, that she can’t remember these positions and theirs order and she needs in help of “instructor”. This is the first sign, that something is wrong with her (even if she’s completely innocent and understands nothing).
The second one thing – check her body constitution – it’s very important image. She has a torso constitution of 40 y.o. woman. As you understand it – it’s not an usual situation for 18 y.o. normal girl, but for girl-oligophren this is an ordinary sitation, - like the following of accelerated growth and hormonal disfunction, that often provoques not only accelerated development of oligophren body, but also some disproportions in it (and also the disproportions of internal organs – f.e. 18 y.o. oligophren can have the heart of 10 y.o. girl). Like an illustration – check first the time “00:03” and examine her legs (you can see the visible movement of muscles, that is completely normal and visible for the legs of 40 y.o. woman, but not visible and not normal for the legs of 18 y.o. girl – these movements can be also observed during the whole episode) and second check the time “00:29” – you can see YN thin legs of 18 y.o. girl and you can compare them to YN torso and body of 40 y.o. woman. Her famous breasts are also the part and the result of this hormonal disfunction (theirs shape and form are the shape and form of 40 y.o. woman, having by mystery the young girl’s skin). As I wrote if before, the origin of oligophrenia is in disfunction of “h.talamus” or of “talamus” (small brain organoids, “responsible” for normal function and balance of endocrynological system), - then they are underdeveloped or if they have any pathology – the body development can become very fast (it also concerns the puberty and development of sexual organs), - that manifests with evidence the case of oligophrenie – most of oligophrens already have well-developed bodies in young age. Like YN has it in our case (not only her – I have seen enough girls-oligophrens during my work and I can say that for them this is normal situation – 13 y.o. girl can easily look like 25 y.o. woman).
The time “00:38” – “excellent” smile for normal 18 y.o. girl. This is a typical smile of girl/boy-oligophren.
The time “00:51” – you can observe again YN 40 y.o. body constitution, as also you can examine well her forms – they look like “clumsy work made of wood” – very well, but crudely done. This is almost common body constitution and its forms structure for girls-oligophrenes (I described the reasons of it before).
The time “01:00-01:12” – famous naivety of girl/boy – oligophren, as also the “famous” specific expresiion of oligophren’s face (also know as “Parker case”

. Then the camera is close to YN face, they both become visible and evident even for not-specialists.
That’s all for this clip. However, in other clips there are more specific traits, that allow to say with almost 100% evidence, that YN is girl-oligophren. Anymore questions ?
