Dependency is a relationship between one or more individuals, entities or objects in which one or some need the attention, characteristics or specifications of the others to exist, function or do the task for which they were conceived or created. To living beings, any number of dependencies are known, the vast majority attributed to human behavior, however, living beings supply their needs and dependencies in a different way, based on their instincts and actions than with their inferior human mind. they are capable of doing.
This type of dependency connection between two or more entities can be described in simple examples for a comprehensive assimilation of the simplest idea of what a dependency is: Human beings at birth depend on who is older, who conceives it, doctors and caregivers on the spot to survive. In fact, no living being, no matter how wild, can survive the new world it will face without at least a primary care given by its instinct or knowledge.
In politics, the institutions that depend on the central government are those that need a subsidy to maintain their offices, trades and workers. The government also needs to depend on a judicial, administrative and legislative system to carry out its functions effectively. Education is also a social system based on dependency, because people from an early age based their academic and intellectual training on a program taught by a teacher facilitator through the didactic content of an educational program.
Medicine for its part offers us a notion of dependence that is a little more complex. Patients with drug addiction should be treated with treatments based on the eradication of that need for harmful and psychotropic substances. Medical treatments generate severe withdrawal and dependence syndromes, while certain types of treatments are the only possibility for a person to stay alive for a longer time. Medicine in turn is in charge of generating a business in which patients, in addition to being "drug addicts", are the best customers of the system.
