What stage in a person’s life coincides with the period of maturity?

There are age periods in a person’s life: childhood (0-10 years), adolescence (10-15 years), adolescence (15-18 years), youth (18-30 years), maturity (30-60 years), old age ( over 60 years). The period of maturity is the peak of the development of a person, both an organism and an individual. This is the longest, most active and productive period, since a person defines life goals and has the strength to achieve them. It comes with the acquisition of life experience, new qualities appear: realism comes to replace youthful maximalism.
