Bone is constantly regenerating, but density declines after age 30
Bone is a dynamic tissue that undergoes continuous destruction and reconstruction, much like renovating a high-rise building. This process continues throughout life, with old bone tissue being removed and new bone tissue forming.
However, upon reaching age 30, the rate of bone destruction begins to exceed the rate of reconstruction. This gradually lowers bone density, weakening the internal structure of bones like a sponge and increasing the risk of fractures.
