Explain what is life cycle of human

The human life cycle is a series of stages a person goes through from birth until death. It includes:

1. Infancy (birth to ~1 year): Rapid growth and development, learning basic motor skills.
2. Childhood (~1 to 12 years): Continued physical, cognitive, and social development. This is often broken into early childhood (toddler years) and middle childhood.
3. Adolescence (~12 to 18 years): Puberty, significant physical and emotional changes, identity formation.
4. Adulthood (18+ years): Reaching maturity, often involves career, relationships, and potentially starting a family. This stage is long and can be divided into early, middle, and late adulthood.
5. Old Age (typically 65+ years): Physical decline, reflection, and often retirement.
6. Death: The end of the life cycle.
