There is scientific evidence to suggest that life can continue after death, according to the largest ever medical study carried out on the subject. A team based in the UK has spent the last four years seeking out cardiac arrest patients to analyse their experiences, and found that almost 40 per cent of survivors described having some form of awareness" at a time when they were declared clinically dead. Dr Sam Parnia ... who led the research, said that he previously [believed] that patients who described near-death experiences were only relating hallucinatory events. One man, however, gave a "very credible" account of what was going on while doctors and nurses tried to bring him back to life - and says that he felt he was observing his resuscitation from the corner of the room. About the evidence provided by a 57-year-old social worker ... Dr Parnia said: "We know the brain can't function when the heart has stopped beating. "But in this case, conscious awareness appears to have continued for up to three minutes. "The man described everything that had happened in the room." Dr Parnia's study involved 2,060 patients from 15 hospitals ... and has been published in the journal Resuscitation. Of those who survived, 46 per cent experienced a broad range of mental recollections, nine per cent had experiences compatible with traditional definitions of a near-death experience and two per cent exhibited full awareness with explicit recall of "seeing" and "hearing" events - or out-of-body experiences.
