Are human bones really stronger than steel?
Science check: Bones are remarkably strong for their weight, but saying they are simply “stronger than steel” is misleading. Results depend on the type of steel, the direction of force, and whether scientists measure strength relative to weight. Bone also changes over time as a living tissue. Explore research on bone strength.
