According to the theory of functional equivalence, any dynamic stereotype is an example of the fact that a person, in certain typical situations, has found ways to eliminate constantly emerging imbalances. A change in behavior, a change in a dynamic stereotype will always be associated with the appearance of emotional stress.  Does it make sense to abandon the old dynamic stereotype, even if it leads to deterioration of health, if a new one, in the phase of its formation, will lead to discomfort and unpleasant sensations? It makes sense if breaking the stereotype will lead to an understandable and desired improvement in the state of health for the individual. Or, if a new stereotype leads to an increase in the quality of life of an individual or (and) those who are extremely dear to him. A necessary condition for the success of building a new dynamic stereotype is a background of positive emotions at the end of each stage.
