What Causes Aging? The Science Behind How We Grow Older

What causes aging is a question at the heart of longevity science, and this video explores the biological processes that help explain how we grow older. We look at the mechanisms behind aging, including cellular damage, inflammation, metabolism, and the gradual decline in repair systems that support healthy aging and long-term healthspan. Full article: https://longevityinsights.co.uk/what-causes-aging/ Aging is not caused by one single factor. It is a complex process involving changes in biomarkers, mitochondrial function, DNA damage, cellular senescence, chronic inflammation, and shifts in metabolic health over time. Understanding these mechanisms can help explain why aging affects the body differently from person to person and why lifestyle factors may influence healthspan, resilience, and biological function as we age.
