Your Skeleton Is Always Rebuilding

Your bones are not permanent, They constantly rebuild themselves. Even though bones

feel solid, they’re living tissue. Inside your bones, two types of cells are working all

the time. One breaks old bone down. The other builds new bone back up.

This process is called bone remodeling. Every year, you replace around ten percent

of your skeleton. That’s how bones heal after injuries and stay strong as you move and

grow. You’re slowly rebuilding your entire skeleton.
