Almost always, the prevention appears as one of the essential tools, or even indispensable, to tackle this type of complications, and possibly the most certain and effective. That’s why, do need to develop to achieve pleasing results. Promote habits, promote and defend practices that prevent unwanted consequences or protect the individual against potential aggressors, well with objects, either providing him with information, resources or personal skills, are the main actions that will come to mind when we hear of prevention, and in some cases it is very difficult to separate a policy or prevention of any action, since always, any intervention prevents us always a situation of worse prognosis.
