At what moment are you dead

Humans have been captivated by death and resurrection for as long as we can remember. The dead keep returning, from our earliest mythologies to the most recent blockbuster movies, according to nearly every faith in the globe. But is it actually feasible to rise again? And anyhow, what actually distinguishes a dead corpse from a living one? We must first comprehend what life is in order to comprehend what death is. One old view was vitalism, which held that the reason why living things were exceptional was because they contained a unique component, or energy, which was the essence of life. Whether it was known as qi, lifeblood, or humors, there was a widespread belief in such an essence throughout the world. This idea is still present in tales of monsters who can somehow sap another person's life or of magical sources that may restore it. Following the Scientific Revolution in the 17th century, vitalism started to lose popularity in the Western world. René Descartes promoted the idea that a divinely created soul residing in the pineal gland of the brain gave life to the human body, which was fundamentally no different from any other machine. And in 1907, Dr. Duncan McDougall went so far as to assert that the soul had mass, weighing patients before and after death to support his assertion.There are still references to his thesis in popular culture despite the fact that his experiments, like the rest of vitalism, were disproved. Where do all these debunked hypotheses leave us, though? What we now understand is that life actually resides inside the active biological processes themselves, not in some mystical substance or spark. And we must enlarge our view to the level of our individual cells in order to comprehend these processes. Chemical events are ongoing inside each of these cells, fuelled by the glucose and oxygen that our bodies turn into ATP, a molecule that transports energy. For everything from repair to growth to reproduction, cells require this energy.The required molecules require a lot of energy to create, and even more energy to transport them to their final locations. Entropy is a universal phenomena that causes molecules to randomly diffuse, move from high concentration to low concentration, or even disintegrate into smaller molecules and atoms. Therefore, cells must constantly use energy to maintain their molecules in the extremely complex configurations required for biological functions to take place in order to keep entropy under control.Death ultimately follows from the breakdown of these arrangements when the entire cell is overcome by entropy. This is the reason why it is impossible to revive a creature that has already passed away. Air can be pumped into someone's lungs, but if the several other processes essential to the respiratory cycle aren't working, it won't be much use. Similar to this, the electric shock from a defibrillator resynchronizes the muscle cells in an abnormally beating heart so they resume their normal rhythm rather than jump-starting an inanimate object's heart. This can save someone from dying, but it cannot bring back a dead corpse or a monster made of dead bodies.It appears that despite all of our different medical wonders, death cannot be stopped or stopped from occurring. But that's not as easy as it might seem because ongoing medical and technological developments have led to diagnoses like coma, which describe potentially treatable situations for which people would previously have been regarded as dead. The line of no return might be stretched even further in the future. Some animals have been observed to lengthen their lifespans or endure harsh environments by practically pausing their basic processes. Cryonics research aims to accomplish the same by freezing the dead and resurrecting them when better technology is available. As you can see, when cells are frozen, diffusion all but ceases and there is very little molecular motion. A swarm of nanobots could theoretically turn back the clock on a person's cellular processes even if they had already stopped altogether. They could do this by repositioning every molecule in the body and simultaneously injecting ATP into every cell, causing the body to resume its normal functions. Therefore, death is just the result of growing entropy that upsets this delicate equilibrium if we consider life to be a state of immensely intricate, self-perpetuating organization rather than some mystical spark. And it turns out that the point at which someone passes away entirely depends only on how much of this entropy we are now able to reverse, rather than being a fixed constant.
