The human body is the tool that allows us to experience life through the senses, faculties and talents, with whom and through, we come into contact and relationship with the environment.

The chemical, sensory apparatus, the psychological mechanics, are just some of the tools in itself perfect, but often fallible and potentially misleading in their use, but allowing us to interpret the world in which we live and interact.

It can be said that essentially, in its primary function, much of what we are biologically, thus also psychologically and cerebrally, is a very efficient defense system, which is designed and programmed in almost all of its capabilities, primarily to protect against environmental threats of any kind by us perceptible.

If we put a hand on a hot radiator, we burn, if we do not move right away, we receive a sensorial pain signal, as it is also true that if it crosses our minds an unpleasant thought, even the chemical balance, following a nerve stimulation, at that time will undergo a change, to make us feel unpleasant sensations, which warn us, through the body, that the thought (or the cause that generates it) is not good for us, producing stress and triggering other psychological mechanics that undermine the well-being in the immediate, communicating the need to put a remedy to the source of the discomfort, always with the ultimate goal, then, to preserve our integrity, whatever the aspect concerned.

When this biological machine essentially perfect, feels safe, then begins to put in use senses, skills and quality, not only in order to preserve itself, but to express themselves and be realized, allowing them to exploit the potential of the individual.

It is in the hereditary factor, expressed through the hereditary characters, at their turn, determined by genes, in which resides the traits which determine the individual's potential.

It is in the manifestation of the characteristics that occurs during the interaction with the environment, that the human body, using the chemistry, as well as the physical and mental faculties, concentrates into something undoubtedly higher than the mere self-preservation, and it is only in these circumstances, the individual has the opportunity to develop and exercise their actual and real potential, and it is here that the concept of "life" finally transcends that of mere existence, to indicate a new horizon, different and distinct for each of us.

At the same time, one can comprehend how a perfect tool as the body, as seen in its entirety, with obvious reference also to the nerve and brain complex, can deceive, when the intellectual resources are not able to cope with the situations, and then with the environment. It can be fascinating, to make a self-analysis, during the day, or even during the week, with estimates of all our wrong impressions of which we realized, we had failed to perceive efficiently people and environment. Often we are not aware of our own effective fallibility, because we tend to notice most of the errors that generates consequences and practical implications.

The reality of the environment may not be as easy to interpret as it may appear more often and in addition, the psychological and chemical body factor, can easily distort further an objective view, where there are no sufficiently capable tools, intended as the ability to interpret it.

Take for example all those things, commonly regarded as the material source of well-being, such as certain forms of leisure, relationships with the opposite sex or the fulfillment of professional and economic ambitions and ask ourselves, how the individual, case by case, is more or less able to manage the impact of these experiences in his life.

There are many cases of people who end up compromising themselves seriously, in every aspect, to pursue passions and experiences, of which do not really know how to handle the emotional and psychological impact; just think of those who have squandered fortunes in sexual adventures or who is ruined by gambling, drugs or other vices.

Probably is not the experience itself the problem, but the ability to manage itself, which can only be determined by the individual's cognitive ability and the inner fruit that has derived from the experiences.

It is plausible to assume that the more an experience has been internalized, the more the latter, belongs to us, under a certain point of view of the inner assimilation; This automatically implies a decline in the need to repeat it.

A simple example might be a 7 year old child who begins to drink milk with chocolate, maybe at the beginning he will perceive it as a phenomenal experience, but then, gradually, he will better manage the desire of it. With age the experiences become more complex, but the mechanics remains unchanged, while changing the complexity of the object of the experience, such as being an undoubtedly more simple internalize the experience of consumption of a beverage, than the relationship with the opposite sex or the vices and passions of every kind, as well as any ambition degenerated into something pathological.

It is at this point that it seems legitimate to ask what is the proportion of real mental and psychological independence attributable to an individual who has come to be dominated by any addiction, be it alcohol, drugs, or other vices, without excluding the occurrence of difficulty of self-control in the sexual sphere (often misunderstood with the "sentimental life"), which may result in dangerous compromises in choosing the partner; this question, is placed under an overall point of view, in an attempt to determine which is the boundary beyond which, a mind is sufficiently capable of metabolizing and understand an experience, to the point of internalize enough to be finally capable to "choose" when in front of a potentially tempting situation, rather than being overwhelmed. It is questioned the very effective individual ppsychological independence in relation to its intellectual limits.

It must be underlined that in addition to personal limitations in intellectual ability, several aggravating factors could easily worsen the whole, as environmental's and the general life experience of the person concerned.

At the same time, it is essential to admit, that whatever the individual's resources and the consequent ability to metabolize and internalize the experiences, is still needed the experience lived and repeated an appropriate number of times before being assimilated and absorbed sufficiently.
