Health is a result of dynamic relationship between the being and the medium. As well, the disease is also the product of asymmetrical and disharmonious interaction between these entities, that is against both beings and society´s evolution.Whether the person is capable of overcoming this gap, than he will remain healthy. Otherwise, he becomes ill. The best defi nition of “normality” implies dynamic interaction, understood as harmonious adaption in any moment of existence. This process is developing depending on the environment, person´s or society´s part. The “normality” is a qualitative result of the person – medium interaction and not only the absence of disease or “migration” in the ocean of possibilities.
