Or if the hair cells in your ears all die, you can't hear. We now know why that is. They're not punished by God. They can't hear because the little vibrations in the air that we can't see aren't getting into their brain. So, we take a cochlear implant, we take a microphone, we record the vibrations, we put it into the brain in the right way, and now many people can hear.
