What is the series of stages that individuals go through from birth to death called?

The term that best describes the series of stages that individuals go through from birth to death is the Life Cycle. This concept encompasses all the biological and developmental changes that occur from the initial stages of life, such as infancy and childhood, through adolescence and adulthood, and ultimately to old age and death.

The Life Cycle captures the comprehensive progression of life stages, highlighting that each phase has its own characteristics, challenges, and milestones. It emphasizes the continuity of life experiences and the transformation an individual undergoes over the span of their lifetime. By understanding the Life Cycle, one can better appreciate how physical, emotional, and social changes manifest throughout different phases of life.

Other terms like the Aging Process or Development Stages may refer to specific aspects of growing older or particular phases of development, but they do not encapsulate the complete journey from birth to death as effectively as the Life Cycle does. Lifecycle Analysis, on the other hand, typically relates to assessing products' environmental impacts throughout their life span rather than focusing on human life stages.
