From Birth to Old Age: Human Development
What do you already know about the stages of human life?
Learning Objective
At the end of the lesson you will be able to describe the major physical and emotional changes as humans progress from birth to old age.
What Are the Stages of Life?
Humans go through several key stages: infancy, childhood, adolescence, adulthood, and old age. Let's explore each one.
Infancy
Infancy (0-2 yrs) is a period of rapid physical growth and brain development. Babies learn to move and interact with their environment.
Early Childhood
Early childhood (2-6 yrs) sees growth in language, movement, and social skills. Children become increasingly independent.
Childhood
In childhood (6-12 yrs), individuals experience steady growth, start primary school, and develop strong friendships.
Adolescence
During adolescence (12-18 yrs), puberty causes rapid physical, mental, and emotional changes. Independence grows.
Adulthood
Adulthood (18-65 yrs) is marked by full physical maturity, career development, relationships, and sometimes raising children.
Old Age
Old age (65+ yrs) involves slowing physical abilities. Wisdom and life experience are significant characteristics of this stage.
Physical Changes Across the Stages
Body grows quickly in infancy, then more steadily until adolescence, where major growth spurts occur.
After adulthood, physical strength and senses may decline, and the body takes longer to heal.
Ageing and Decline
Growth and Development
Emotional and Social Changes
Each life stage brings new emotions: infants form attachments, teenagers seek independence, adults build relationships, and older people reflect on life.
Puberty: A Time of Change
Puberty involves hormones, body changes like growth of hair, changing voice (for boys), and beginning of menstrual cycles (for girls).
Adulthood Responsibilities
Adults may start families, pursue careers, and contribute to society in various ways. Emotional management becomes important.
Staying Healthy in Old Age
Regular activity, healthy eating, and staying social can support physical and mental health in older age.
