 Everything in your body, all the cells, everything that runs you is ordered and operated by the brain. And your brain does that communication via the spine. So when you go, when the brain sends a message down, let's say to your heart, it goes down the spine. It goes out a hole between the vertebra and your spine that basically everyone knows disc or for cushions, but they're also shims. And they hold open the holes called foramen. And the nerves come off your spinal cord. In this case, it goes to your heart and says, hey, buddy, you beaten. And the heart sends one back up in a loop and says, yep, guy, I got it. We're doing it.
