The human life cycle document outlines the main stages of human development from infancy to old age. It describes the key changes that occur in nutrition, interaction, and reproduction at each stage. The stages are infancy (0-6 years), childhood (7-12 years), adolescence (13-19 years), adulthood (20-64 years), and old age (64+ years). At each stage the body's needs and capabilities change as it develops and ages.
