Your skeleton is never more than ten years old
Bone might feel like an inert, permanent scaffolding, but it is living tissue in constant flux. Specialized cells called osteoclasts constantly break down aged bone matrix, while osteoblasts lay down fresh mineralized collagen in its place. This continuous cycle, known as bone remodeling, replaces roughly ten percent of your adult skeleton every single year—meaning virtually every bone in your body is completely rebuilt about once a decade.
