Final answer:
Good health in old age is predominantly attributed to good health habits and care throughout one's life, especially in adolescence and adult years. Access to quality healthcare, advancements in medicine, and healthful lifestyle choices have all played a role in improving the quality of life for the elderly.
Step-by-step explanation:
Good health in old age is a multifaceted issue that can be primarily attributed to good health in adolescence and adult life (B). This lifelong approach to maintaining health is critical, as it helps to lay the foundation for health in later years. Sociological studies suggest that healthy behaviors and regular medical care throughout a person's life contribute to better health outcomes as one approaches old age. Factors such as access to quality healthcare, advancements in medical technology, and the promotion of healthful lifestyles—emphasizing nutrition and exercise—play significant roles in improving the quality of life for the elderly.
Moreover, the sociological impact on health is evident when considering how social behaviors and lifestyle choices directly affect health. The reduction in smoking, better dietary habits, and greater awareness of the importance of hygiene have all contributed to a rise in life expectancy. Even cultural attitudes toward aging and the respective value placed on elderly people in a society can have an impact on their overall health.
Lastly, while chronic diseases such as arthritis, hypertension, heart disease, and cancer remain common among older individuals, medical advancements have helped to manage these conditions more effectively, reducing their disabling effects. Consequently, maintaining a proactive approach to health throughout all phases of life is essential to achieving better health outcomes in old age.
