Final answer:
Healthy aging is promoted through exercise, good nutrition, sleep, and relaxation.
Step-by-step explanation:
Healthy aging is promoted by a combination of factors including exercise, good nutrition, sleep, and relaxation. Exercise helps to maintain muscle strength and flexibility, while good nutrition provides the necessary nutrients for healthy bodily functions.
