Just been reading this (SLI ignoring function):

objective sensoring ( ): the zone of ignoring. People of this type may be inattentive to their own appearance, to the interior of their house, to other people’s behavior even if their actions influence them directly. They are not fit for any monotonous work, for example, for work at the conveyor assembly line. They need to pay special attention and make extra efforts to keep up their appearance. They do not have a natural feeling for style in clothes. They often ignore parents or peer pressure. Children of this type may seem to be very stubborn.
Which I find quite interesting. Something that's puzzled me recently, is myself and my SLI friend tend towards a more unkempt appearance. I've struggled at times to look good, look presentable in the world, something I forget to pay attention to.

I've wondered at times, as i've read that Si is to do with looking good, appearance and such, which I would not rate as my strength, although I do have more of a means for it now, can do it some more, but still....

On another note, i've tended to compensate with being in reasonable physical shape, on the thought of ok... perhaps look a bit unkempt etc, but at least it's balanced out with a healthy body, which is probably a compensation attitude.
