death is the irreversible cessation of all biological functions that sustain an organism.for organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including the brainstem, and brain death is sometimes used as a legal definition of death.the remains of a former organism normally begin to decompose shortly after death.death is an inevitable process that eventually occurs in all organisms.some organisms, such as turritopsis dohrnii, are biologically immortal.however, they can still die from other means than aging.figuring out when someone is dead has been a problem.initially, there was the definition of death when breathing and the heartbeat ceased.however, the spread of cpr no longer meant it was irreversible.brain death was the next option, which fractured between different definitions.some people believe that all brain functions must cease.some believe that even if the brainstem is still alive, their personality and identity are dead, so therefore, they should be entirely dead.death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis.something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die, as a virus is not considered alive.as of the early 21st century, 56 million people die per year.the most common reason is cardiovascular disease, which is a disease that affects the heart.many cultures and religions have the idea of an afterlife and also may hold the idea of judgment of good and bad deeds in one's life.there may also be different customs for honoring the body, such as a funeral, cremation, or sky burial.death is actively trying to be cured by a group of scientists known as biogerontologists, through seeking to do the same as biologically immortal organisms do and applying a similar means to humans.however, as humans do not have the means to apply this to themselves, they have to use other ways to reach the maximum lifespan for a human, such as calorie reduction, dieting, and exercise.there are many scientific approaches and various interpretations of the concept.additionally, the advent of life-sustaining therapy and the numerous criteria for defining death from both a medical and legal standpoint have made it difficult to create a single unifying definition.as a point in time, death seems to refer to the moment when life ends.determining when death has occurred is difficult, as cessation of life functions is often not simultaneous across organ systems.such determination, therefore, requires drawing precise conceptual boundaries between life and death.this is difficult due to there being little consensus on how to define life.it is possible to define life in terms of consciousness.when consciousness ceases, an organism can be said to have died.one of the flaws in this approach is that there are many organisms that are alive but probably not conscious.another problem is in defining consciousness, which has many different definitions given by modern scientists, psychologists and philosophers.additionally, many religious traditions, including abrahamic and dharmic traditions, hold that death does not (or may not) entail the end of consciousness.in certain cultures, death is more of a process than a single event.it implies a slow shift from one spiritual state to another.other definitions for death focus on the character of cessation of organismic functioning and human death, which refers to irreversible loss of personhood.more specifically, death occurs when a living entity experiences irreversible cessation of all functioning.as it pertains to human life, death is an irreversible process where someone loses their existence as a person.
