Lifecycles

  • Throughout our lifetimes, as we grow from infancy to old age, we undergo changes and development.

Human Lifecycle

There are six stages in the human lifecycle:

  • Foetus Stage: This initial phase marks the development of a baby inside the mother's womb. It is a crucial period for growth and formation.
  • Baby Stage: Following the gestation period, a baby is born, symbolizing a new beginning and the start of a remarkable journey.
  • Childhood Phase: During childhood, individuals learn fundamental skills like walking and talking, laying the foundation for their future growth.
  • Adolescence Period: Adolescence bridges childhood to adulthood, characterized by significant physical and emotional changes during puberty, shaping one's identity.
  • Adulthood Stage: This phase signifies the peak of physical development and maturity, where individuals may choose to start families and pursue their aspirations.
