The cryopreservation of humans or large animals is not reversible with current technology. The stated justification for cryonics is that people considered dead under current legal or medical definitions do not necessarily have to be dead under the stricter definition of death. [19] [39] Historically, attempts to define the exact time of a person`s death have been subjective or inaccurate. Death was once defined as stopping the heartbeat (cardiac arrest) and breathing, but the development of CPR and immediate defibrillation has made this definition inadequate, as breathing and heart rhythm can sometimes be resumed. This type of death, in which circulatory and respiratory arrest occurs, is called the circulatory definition of death (DCDD). SDTC proponents believe this definition is reasonable because a person with permanent loss of circulatory and respiratory function should be considered dead. [9] Critics of this definition argue that while the termination of these functions may be permanent, this does not mean that the situation is irreversible, because if CPR were applied, the person could be resuscitated. [9] Therefore, the arguments for and against the DCDD boil down to defining the words “permanent” and “irreversible”, which further complicates the difficulty of defining death. Moreover, events that were causally linked to death in the past no longer kill in all circumstances; Without a functioning heart or lungs, life can sometimes be sustained with a combination of life-sustaining devices, organ transplants, and artificial pacemakers. To die is a verb.
When a person, animal or plant dies, it ceases to live. Other forms of “dying” are dying, dying, dying. In addition to the issue of advocacy or defense against brain death, there is another problem inherent in this categorical definition: the variability of its application in medical practice. In 1995, the American Academy of Neurology (AAN) established a set of criteria that became the medical standard for diagnosing neurological death. At that time, three clinical features had to be fulfilled to determine “irreversible withdrawal” of the entire brain, including: coma with clear etiology, respiratory arrest, and lack of brainstem reflexes. [14] This set of criteria was last updated in 2010, but there are still significant differences between hospitals and medical specialties. [14] It is possible to define life in terms of consciousness. When consciousness stops, we can say that an organism is dead. One of the shortcomings of this approach is that there are many living but probably unconscious organisms (for example, single-celled organisms). Another problem is the definition of consciousness, which has many different definitions by modern scientists, psychologists and philosophers.
In addition, many religious traditions, including the Abrahamic and Dharmic traditions, hold that death does not bring (or bring) the end of consciousness. In some cultures, death is a process rather than a single event. This involves a slow transition from one spiritual state to another. [7] Death plays an important role in Buddhist teaching and practice. Awareness of death was what motivated Prince Siddhartha to fight for the “immortal” and eventually attain enlightenment. In Buddhist teachings, death functions as a reminder of the value of being born as a human being. Being born as a human being is considered the only state in which enlightenment can be attained. Therefore, death helps to remind us that life should not be taken for granted.
The belief in rebirth among Buddhists does not necessarily eliminate the fear of death, because any existence in the cycle of rebirth is considered filled with suffering, and being reborn many times does not necessarily mean progress. [66] Smith attended both funerals as a police officer and as the husband of police officer Moira Smith, who died on 9/11. Much interest and debate revolves around the question of what happens to consciousness when its own body dies. The belief in permanent loss of consciousness after death is often called eternal forgetfulness. The belief that the stream of consciousness is preserved after physical death is described by the term after death. Both will probably never be confirmed without the perpetrator actually having to die.
