Is it possible to return from the dead ?

Dr. Sam Parnia has taken a closer look at how someone can be revived up to several hours after death.
The key is in determining at what point the patient is actually dead and at what point it becomes impossible to revive them. It is now believed that the brain cells remain viable for as long as eight hours after a person is otherwise declared clinically deceased, but finding a reliable way to resuscitate someone within this time frame remains a problem that science has yet to solve.

"We now understand that its only after a person has turned into a corpse that their cells are undergoing death, and if we therefore manipulate those processes, we can restart the heart and bring a person back to life," said Parnia.
Dr. Sam Parnia, a critical care doctor and the director of resuscitation research at Stony Brook University School of Medicine, has written a new book discussing ways in which people can be resuscitated after they previously would have been considered clinically dead.

I remember reading in a biography of George Washington that being buried alive that way was a real fear in colonial times and that Washington made special terms in his will about this to be really sure he was dead before they buried him. I also recall reading that this may have been one of the sources of vampire myths -- people trying to dig themselves out of shallow graves in Eastern Europe scaring the locals.

the speed of `death diagnosis` is directly proportional to the amount of people on earth .

Im sure scientists already knew about these things for many decades, so why cant they use it right now on humans. The russians did a successful revival of a headless dog in the 1940s. If it helps the human society why not just use it, rather than keep bragging they can do this, they can do that, but still nothing happens.

I have always understood that 4 minutes after clinical death the brain becomes so much damaged, due to lack of oxygen, that if revival were successful the person would be seriously mentally impaired. So what's all this talk about 8 hours? It is a interesting point! I don't see any good reasons bringing back to life a human if there brain will be in a "zombi mode". It will be just a living corp....or science is also wrong about 4-5 min deadline. But If stem cells science improves and can repair the brain cells, then the deadline will be truly 8 hours or more.

Waking up in a coffin must be worse than dying.
