Late adulthood, also known as old age, is typically defined as beginning at age 60. This stage is characterized by physical and mental decline. Individuals experience a loss of jobs and independence as they retire from work. They also fear changes to their health. Late adulthood involves adjusting to age-related changes like decreasing strength, retirement, loss of a spouse, and reduced social roles. Maintaining good physical and mental health through diet, exercise, and social engagement can help support a longer, healthier life in old age.
