The heart has been working all night.

You did not feel it. You were not awake to notice. But it was there in the dark, in the silence, in the hours when your mind went away and left the body to do what the body does without supervision. Beating. Filling. Emptying. Sending blood out to the edges of you and pulling it back in. The quiet hydraulic work that does not ask for applause or acknowledgment. Just working. Just continuing. Just keeping you alive while you slept.

It is working now. You can feel it if you stop and put your attention there. Not loud. Not dramatic. Just the steady thump behind your ribs. The small pressure. The pulse. The muscle that has been contracting and releasing since before you were born. Since before you had thoughts or language or any idea what a heart was. It knew its job before you knew yours. And it has not stopped. Not once. Not for a single moment in all the years you have been walking around inside this body.

Your lungs are filling. Right now. Without you deciding to fill them. The diaphragm pulling down. The ribs spreading. The air coming in through your nose and traveling down into the small branching pathways that you cannot see and do not control. The oxygen moving across membranes so thin you could not build them if you tried. Moving into your blood. Your blood carrying it. Your heart pumping it. The whole system running itself. The whole system that keeps you conscious and upright and able to read these words.

You did not design this. You did not build it. You did not choose the shape of your lungs or the rhythm of your heart or the way your blood knows where to go. You just inherited it. You just woke up inside a body that already knew how to breathe. And it is still breathing. Still doing the work. Still keeping you here.

Your legs are holding you. Or they held you yesterday. Or they will hold you in a few minutes when you stand. The bones stacked. The joints hinged. The muscles wrapping around the frame and pulling and releasing and pulling again. The whole architecture of standing. The whole engineering problem of keeping a tall unstable thing upright and moving. Your legs solve it. Every day. Every step. They carry your weight and the weight of the vest and the weight of the years and they do not quit. They do not refuse. They just do it. They just carry.

The feet at the bottom of the legs. Ten toes. Two arches. The small bones and tendons and ligaments all working together to make contact with the ground and push off and land again. Your feet do not think about walking. They just walk. They have walked so many steps you could not count them. They have carried you through every place you have ever been. Every park. Every room. Every threshold. And they are still here. Still capable. Still willing to meet the floor when you ask them to.

Your hands are resting. On your lap, maybe. Or on the bed. Or holding this device. And they are doing the smallest work. The work of just being hands. Feeling the texture of fabric or skin or screen. The fingertips receiving information. The palms holding warmth. The knuckles bending slightly. The hands that have built and typed and held and lifted. The hands that have touched your children and your wife and your father. The hands that are still yours. Still working. Still sensitive. Still able to feel the difference between rough and smooth, between warm and cool, between here and there.

Your eyes are open. The pupils adjusting to the light in the room. The lens focusing. The retina receiving the shapes and colors and translating them into signals your brain can read. The whole miraculous apparatus of seeing. The fact that you can look at a face and recognize it. That you can read letters on a screen. That you can see the morning light coming through a window and know what time of day it is. Your eyes do this. Your eyes are doing this right now. Letting the world in. Letting you see.

Your spine is holding you up. Even lying down, it is holding its shape. The vertebrae stacked. The discs between them cushioning. The whole column of bone and cartilage that keeps you from collapsing into yourself. Your spine has been doing this since you were born. It has grown with you. It has bent and straightened and carried the load. And it is still here. Still doing the work. Still the central structure everything else hangs from.

The blood is moving. Right now. Through the arteries. Through the veins. Through the capillaries so small you cannot see them. The blood carrying oxygen and nutrients and everything the cells need to keep doing what they do. The blood cleaning itself. The blood returning to the heart and being sent out again. The loop. The circuit. The system that does not stop. That cannot stop. That keeps you alive by just continuing to move.

Your skin is covering all of it. The largest organ. The boundary between you and everything else. The skin that feels the air and the water and the fabric and the touch. The skin that heals when it is cut. The skin that warns you when something is too hot or too sharp. The skin that has been with you your whole life. That has stretched and scarred and aged and stayed. The skin that is still here. Still doing its work. Still holding you together.

The stomach is digesting. Or it will be soon. Or it was a few hours ago. Breaking down food into pieces small enough to use. Pulling out the energy. Sending it where it needs to go. The intestines continuing the work. The whole long process of turning what you eat into what you are. The body knowing how to do this. The body doing it without asking you. The body feeding itself. Sustaining itself. Keeping itself running.

Your brain is reading this. Right now. The neurons firing. The synapses connecting. The electrical signals moving faster than you can track. The brain that is somehow aware of itself. That can think about thinking. That can notice the heart beating and the lungs breathing and the eyes seeing. The brain that holds your memories and your language and your sense of who you are. The brain that woke up this morning and is still here. Still processing. Still aware. Still you.

The body is a system of systems. All of them running. All of them coordinated. All of them doing their work without needing you to manage them. You do not tell your heart to beat. You do not remind your lungs to breathe. You do not schedule the blood to move or the stomach to digest. It just happens. The body just does it. The quiet machine just runs.

And it has run all night. And it is running now. And it will run tomorrow. Not forever. You know that. The machine will stop one day. But it has not stopped yet. It is still here. Still working. Still carrying you. Still breathing and beating and moving and feeling. Still alive. Still capable. Still yours.

You do not need to fix it. You do not need to optimize it. You do not need to make it better or faster or stronger. You just need to notice it. Just need to feel the heart beating. Just need to take a breath and know that the breath came. Just need to stand and feel the legs hold you. Just need to look and see that the eyes are still working.

The body is not a problem to solve. It is a gift you are inside. A machine you did not build but get to use. A system that has carried you this far and is still carrying you. And this morning, before anything else, the gratitude is this: it is still working. The heart is still beating. The lungs are still breathing. The legs are still standing. The hands are still holding. The eyes are still seeing.

The body is still here. And you are still in it. And it is still doing its quiet astonishing work. Not loudly. Not dramatically. Just steadily. Just continuing. Just being the body that keeps you alive. The body that lets you walk and work and hold your children and sit with your father and lie beside your wife. The body that is the floor underneath everything else you do.

The machine is running. And this morning, that is enough.
