This research area explores the physical, mental, and social aspects of aging, and investigates how factors such as genetics, lifestyle choices, and healthcare access can impact the health and well-being of older adults. Researchers in this field often focus on identifying strategies to promote healthy aging, prevent age-related diseases, and improve the quality of life for older populations. Topics of study may include chronic diseases, cognitive decline, mobility limitations, caregiving, end-of-life care, and healthcare policy for older adults.
