How Mitochondrial ‘Rubbish DNA’ May Drive Age-Related Inflammation—and What It Means for Healthy Aging
Understanding the Mitochondrial Mess Behind Aging As people live longer, researchers are increasingly focused on the tiny powerhouses inside our cells: the mitochondria. A new line of investigation suggests that a surprising source of chronic inflammation in aging may lie within the mitochondria themselves. When these organelles mismanage their own DNA, they can release material…

Empirical Study on 15-Minute Fitness Circles and Health in Chinese Older Adults
Background and Significance As the global population ages rapidly, finding accessible, scalable strategies to promote healthy aging is essential. A robust body of research links physical activity to better health outcomes for older adults, including improved mobility, mood, and chronic disease management. In this context, 15-minute fitness circles have emerged as a practical, low-cost approach…

An Empirical Study of 15-Minute Fitness Circles and the Health of Chinese Older Adults: The Mediating Role of Physical Activity
Introduction As the global population ages, finding accessible, time-efficient ways to promote health becomes a public health priority. This empirical study investigates 15-minute fitness circles and their impact on the health of Chinese older adults, with physical activity serving as a mediator. The approach reflects real-world conditions where busy schedules and limited resources demand brief,…
