When Are You Dead?By Adam Sinicki
What Is Death?
If you see a individual & think them to be deceased this will usually imply that you have performed the usual checks – you have taken their pulse rate which shows that their heart has stopped beating, & you will have inspected their breathing. If these have both ceased then you will consider the individual to be no longer alive.
However this could be to overlook the fact that an individual can be revived back from that state using procedures procedures such as CPR to once again start the breathing etc. This can be possible even after a a very long duration of time, & that means that simply because somebody's heart has stopped beating that does not imply that they are definitely dead beyond hope. In fact, in some uncommon reports people have been known to come 'back to life from the dead' in their actual coffins & horrifically we often find scratch marks within them when they are dug up. Similarly you could not base the definition of life or death simply on the prevalence of a heart beat, or or you would be able to set up a mechanical pump in a person who had otherwise been declared dead & categorise them as living.
In fact curiously the cells in our bodies do not totally die for multiple weeks which seems to point to the idea that an person could technically be brought back to life should their heart rate be repaired & should O2 be returned to those cells (though it is worth mentioning that after a mere 4 minutes there is neurological damage that is non-reversible to the brain – so you could be brought back but perhaps not with your former shining personality). In fact some individuals will thus try to extend their life spans by freezing their bodies cryogenically – sustaining their bodies' cells so that they do not die, & thus meaning an individual could one day be willing and able to restore their bodies utilising advanced future tech.
Something else fascinating about death, is that immediately following the cessation of the heart rate, the neurons continue to fire. This then means that while someone might be dead by some definitions, they might still be experiencing certain conscious awareness in the form of dreams or random emotions. As brain areas shut down and brain cells died this would then cause a range of experiences similar to having a stroke, advanced meditation, or taking recreational drugs. It seems that there is at least some life after dead, and this could describe many of the phenomena described during death.
Much of the difficulty in defining death spawns from the difficulty with defining life in the first place. A plant for instance is alive yet appears to have zero of the features of consciousness that we think about to be vital for human life (brain death is one legal form of death in some states for instance). At the moment in a persistent vegetative state, which appears to be the body running without any conscious awareness, a patient is thought to be alive, & their 'right to die' is a very difficult subject. As such there & arguments and lots of debates & conferences still that attempt to discover a global state to call 'death'.
Brain Death
In the largest number of countries and states however, death is thought to be indistinguishable from 'brain death' – brain death here being a state in which a individual has no sign of brain function on an EEG (electroencephalograph) or a CAT scan. In the largest proportion of areas of the world that is thought to be to be legal death, except from a few such as New York & New Jersey in the US where it is necessary for the person's heart & lungs to have stopped purpose additionally. This then means that a individual might be legally dead in one state of America but not in an different one. This aptly demonstrates the complex nature & controversy around what death really means, while some of the other factors we've illustrated here likewise demonstrate how perhaps death isn't potentially such a one way street. In the distant future death might not have the same meaning it did before at all. Copyright 2012 The Biomatrix.Net
