Final answer:
Adulthood spans the ages between 25 and 65, with middle adulthood ranging from the mid-30s to the mid-60s. This life period includes raising a family and achieving career goals, alongside the onset of aging signs and health issues.
Step-by-step explanation:
Adulthood covers the four decades of life between ages 25 and 65.
In the United States, adulthood is often considered to start at 18 years old, which is when a person becomes legally responsible for themselves. However, middle adulthood specifically is typically recognized as beginning in the mid-30s and continuing until the mid-60s. During this period, many adults raise a family, strive for career success, and begin to experience the physical signs of aging.
It is also important to differentiate between the stages of adulthood. Early adulthood is when most individuals establish their path in life through education, career, and perhaps starting a family. Middle adulthood is often a time of reaching career goals and coping with the challenges of aging. Finally, late adulthood begins in the mid-60s and lasts until (the end of life), when individuals typically retire and focus more on reflecting on their lives.
