A normal person presents 2.7 symptoms, a neurotic one, 29.3. The rate of somatic diseases per subject is 1.6 and 3.6 respectively. Depressive and neurotic reactions in the form of neurocirculatory asthenia are quite frequent, being predominant in individuals with a shorter length of service, and are associated with financial and household difficulties and dissatisfaction with the present job.
