Answer 1

Explanation:

Adults experiences age-related changes based on many factors: biological factors such as molecular and cellular changes are called primary aging, while aging that occurs due to controllable factors, such as lack of physical exercise and poor diet, is called secondary aging.

In early adulthood (ages 20–40), 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.

Aging speeds up during middle adulthood (ages 40–65) and is characterized by decline in vision, hearing, and immune-system functioning, as well as the end of reproductive capability for women, known as menopause.
