I go to a school that has a large number of deaf students, which means they use ASL to communicate, which requires their hands. It got me thinking about how when we lose a sense it seems one of the first things we learn to do is use our hands to make up for it.
Can’t hear or talk? Use your hands to communicate with sign language. Can’t see? Use your hands to feel your way.
Our hands are important. Built with a lot of internal circuitry that we don’t see, moving all the parts, sending all the signals to the right places.
