The Story of Human Growth: From Baby to Adult

Rapid Rise: Babies triple their birth weight in the first year—one of the fastest growth phases in life.
Head Start: At birth, your head makes up a quarter of your total body length.
Height Highway: Kids typically grow about 2 inches a year after age three.
Peak Velocity: Puberty brings the fastest growth since infancy, with sudden height spurts.
Brain Blaze: By age five, the brain reaches nearly 90% of its adult size.
Changing Proportions: Limbs grow faster than the torso, reshaping body balance through childhood.
Strength Shift: Muscle mass steadily increases through adolescence, especially in teens.
Skill Climb: Fine motor skills refine each year as nerve pathways strengthen.
Voice Journey: The larynx grows dramatically during adolescence, reshaping the voice.
Adult Arrival: Most people reach full height by late teens, but growth continues in other ways.
