Your Bones Are 5 Times Stronger Than Steel π¦΄πͺ It might surprise you, but the human body is built with an incredible natural material — bone — that’s stronger than you think. In fact, human bones are about five times stronger than steel of the same density! This means your skeleton is both extremely strong and amazingly lightweight , perfectly designed to support you through every jump, run, and movement. ⚙️ The Science Behind Bone Strength Bone isn’t just a solid structure — it’s a living tissue made up of a tough outer layer and a spongy inner core. Its unique composition of collagen (a protein) and calcium phosphate (a mineral) gives it both flexibility and hardness. Collagen provides elasticity, helping bones absorb impact. Calcium phosphate gives bones their rigid, steel-like strength. Together, this combination allows bones to withstand pressures that would easily break many metals. A cubic inch of bone can bear a load of about 19,000 pounds — roughly the w...
