In early adulthood (ages 20â40), our physical abilities are at their peak, including muscle strength, reaction time, sensory abilities, and cardiac functioning. The aging process also begins during early adulthood and is characterized by changes in skin, vision, and reproductive capability.
Physical growthâheight and weightâaccelerates in the first half of puberty and is completed when an adult body has been developed. Until the maturation of their reproductive capabilities, the pre-pubertal physical differences between boys and girls are the external sex organs.
