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.
Breasts develop fully between ages 12 and 18. Pubic hair, armpit and leg hair usually begin to grow at about age 9 or 10, and reach adult patterns at about 13 to 14 years. Menarche (the beginning of menstrual periods) typically occurs about 2 years after early breast and pubic hair appear. It may occur as early as age 9, or as late as age 16.
