Description: Nanomechanical medical robots lace the internal hollows of the bones with high tensile strength alloys and then draw the same filaments around the exterior of the bone. The result is an improved skeletal structure that is highly resistant to fracturing or breaking. Bones that have undergone this procedure have a tell-tale metallic sheen to their surface. In game terms, the effect of this cyber is that damage due to falls has a less chance of causing serious injury.
