Late adulthood is the time of life after age 65. During this time, people go through many changes in their physical appearance, including an increase in wrinkles due to less elastic collagen, a decrease in muscle mass, and a loss of height.
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.
