The line between life and death remains unclear, and the exact moment when a cell becomes alive package as well as the point where it ceases to be still living in constant debate. From the medical point of view there is, however, a way to tell exactly when a living organism is completely and unquestionably dead.
Death is somewhat relative, and people who have been declared brain dead or whose heart has stopped beating were observed when they were "revived thanks to modern medical advances.
True death, according to a conference held by TED-Ed motivational platform, is when there is the possibility of being resurrected. This is the point at which there is no return.
All that makes our cells from repairing to an increase in reproduction, is fed glucose and oxygen that our body convert it to ATP, part of the nucleic acids DNA and RNA. Our bodies are the universal law of entropy, which means that these molecules tend to move randomly in areas of high concentration in the low concentration. While cellular process is complex and complicated, simply, entropy always be kept under control for life to count. When this delicate balance takes down results in death.
Lifesaving procedures, such as CPR (cardiopulmonary resuscitation) or defibrillator, can delay or even prevent death but once all succumbed to entropy cell resuscitation is not possible.
Scientists believe, however, that if they are able to find a solution for the cells to survive entropy, may someday overcome "point of no return", effectively revising the definition of death.
