Have you ever felt the entire external surface of your heart as it beats? I am not talking about the heart pounding against your chest when you are stressed or excited, which I guess is technically called palpitations (which I feel particularly when I drink a lot of coffee while fasting).
I am talking about you being able to feel a 3D model of your heart. I am not even sure anyone could feel that way, because I might have been half asleep when I felt it. But it was wonderful and shocking at the same time. Wonderful because I have never felt it before, shocking because it reminded me of the fragility of life. Life. That was it. That was the generator powering my entire body. And there is no backup.
Imagine, after a power cut, you can see a machine running your entire house, far, far away from town. And there’s an important event, like a wedding or a birthday party, going on. Don’t you constantly make sure there’s enough fuel supply for that machine, that everything’s working alright? Well, we don’t behave the same way with our body’s machine, our heart. Until you can see it (or feel it, in this case) like you could a generator.
That feeling was a reminder that life is fragile. And your body is running on a single generator, with no backup at all.
