Bungee jumping involves jumping from a tall structure while attached to an elastic cord. It is an adrenaline sport that requires jumping from a fixed object like a bridge or building, or sometimes from a helicopter. To bungee jump safely, one must be in good physical health without heart conditions and not afraid of heights. Special equipment like a harness, padded bumper, bindings, and gloves are used along with safety measures by a professional operator to control the fall and provide a progressive braking as the elastic cord supports up to a ton of weight.
