Did you know throughout life, you are continually losing and rebuilding bone tissue? It's true. Now, children do make new bone at a substantially greater rate than adults because much more bone is being built than lost during childhood and adolescence, as their bones are growing in both size and density. However, adults are still rebuilding bone tissue throughout their lifespan. Unfortunately, the rate at which adults' bodies can rebuild bone tissue gradually decreases with age, often leading to the development of osteoporosis.
