Losing a limb can be due to any number of reasons, including: cancer, atherosclerosis, diabetes, traumatic injuries, and birth defects. The experience has a huge impact on people's lives, so bionic limbs were invented as a solution. They are state-of-the-art technology that integrate the human body with mechanical parts so that a person may regain movement again with an artifical limb. They are regularly improving with each new discovery the scientific community makes. Commercial prosthesis are getting cheaper and more accessible, and they range from life-like hands that have an increasing variety of movements to make the user feel that they fit in, to high-tech running prosthetics designed to provide speed for athletes, to even bionic eyes. With the speed that prosthesis are evolving at, it might not be so long before we start voluntarily replacing our own body parts with enhanced prosthetics.
