Why Are You Alive - Life, Energy & ATP

Sources & further reading:
At this very second, you are on a narrow ledge between life and death. You probably don’t feel it, but there is an incredible amount of activity going on inside you. And this activity can never stop.
Picture yourself as a slinky falling down an escalator moving upwards - the falling part represents the self replicating processes of your cells, the escalator represents the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.
Somewhat unsettlingly, the universe wants you to reach the top. How do you avoid that and why are you alive?

    Alive from electromagnetic static electricity. Electrical conductivity and density place humans at the low high voltage end of the high voltage scale for all matter. The body works from positive voltage as well as, opposite negative voltages colliding and releasing from the heart. The electrical current flow that occurs in the body as the Earth orbit Microvectors open and close per second; causes Bioluminescence in the body. The light is focused through the eyes and provides vision. Stars flicker occasionally by the same electricity that the body does. The earth itself is the contact point for our body's positive side charge. The air is our negative contact point. The air and earth come into constant contact with each other daily, causing a complete circuit and earth heart beat. Bioluminescence is in the living inhabitants and the atmosphere. Density as well as, electrical conductivity changes in the body causes heart and sight problems. Remember at the universal level; voltages are high enough in human hairs to cause baldness, so bone density stability is how electricity passes through the heart. The medical world can keep a heart pumping artificially when bone density flops: Though the voltages of Jesus are rare. Jesus had powerful universal alignment in timing, so he could raise from death and restore the Bioluminescence for sight. Simulation. My name is Charlie John Thomas

    Good vid, but the whole 'live vs dead universe' thing is very western thinking, and annoying w as much as you use it. There is no such thing as magic. Emergence is a synergistic phenomena based on the fundamental laws of the universe. Everything auto-arranges; no getting underneath that. In that sense, everything is simultaneously 'alive' and 'dead'. edit: yes I understand it was for the entropy angle, but even so, the above is still true.

      I can't say I'm an expert but I will try to explain. Keep in mind I might be wrong. Our bodies produce ATP by taking sugar from plants and animals and the oxygen you breath reacts with the sugar making carbon dioxide and water and energy. This energy is experienced as heat energy which is just faster movement and ATP molecules. These ATP molecules have 3 negatively charged particles that hold energy and as we know similar charges don't want to be near each other so one of these particles is disconnected from the ATP turning it into ADP and this process released heat energy and released that particle and reacts with your cells giving them energy.
