Around 30 years ago, archaeologists in Cairo, Egypt, were excavating the tomb of an
ancient Egyptian royal family member who had lived about 3,000 years ago. They
discovered that her body was fitted with a tiny, prosthetic toe made of wood with a leather
strap that connected it to her foot. Historians refer to it as the Cairo Toe.
Isn’t it amazing that humans were already using artificial body parts—prosthetics—as far
back as 30 centuries ago? Today, we have sophisticated, 3D-printed robotic limbs that can
fully function by connecting directly to a person’s nervous system.
