Health.com: 14 Surprising Facts About Healthy Bones

Your Bones Are Alive

They may feel like rocks, but bones are living things. In fact, a group of cells (called osteoblasts) are constantly churning out new bone, while a second set (called osteoclasts) destroys bone by gobbling it up like Pac-Man.

This constant tug of war between creation and destruction is called bone remodeling.

It’s the reason bones regenerate after a break, grow rapidly during youth, and, unfortunately, decline later in life when the balance tips toward destruction.
