You could read again what I said: no actual basis it's exactly that, but an assumption, which is likely partially true in the sense that there are more cases than what's reported. However, to say grossly underreported when he has no evidence though it's just an assumption.
If there was an 'actual' basis there would be no under-reporting because the unreported cases would be reported, whether later or through a different process.
Whether or not the term 'grossly' is appropriate, is mere semantics. If you wish to use the term 'significantly' under-reported, I have no problem with that. However, there can be different opinions or interpretations of what constitutes 'significant' in a particular set of circumstances. If only half the cases of the ''Lazarus Phenomenon' are reported, does that constitute a 'significant' or a 'gross' under-reporting? This is really a deflection from the main issue which is that all opinions are a result of an interpretation of the evidence available to us.
None of those people was actually reported dead and then woke up, it was just that the resuscitation efforts ended and they regained pulses within 10 min. Most also still died, just later. I saw a couple of cases who allegedly woke up in the morgue but most likely those who called the efforts didn't know what they were doing. Again, using something that's so rare that's practically zero to argue the point that death status it's an opinion and not a fact is just a pedantic exercise.
Read again what I wrote in response to Bart. I wrote: '
Sometimes it is just an opinion', and then gave some examples.
I would agree that in the vast majority of cases when a doctor expresses his opinion that a person's body has ceased to function, he is probably almost always correct, with very few exceptions. However, before the era of modern medicine, I would 'deduce' that the Lazarus Phenomenon would have been more common. There are a number of stories available on the internet, of people who appear to have been buried alive. On the few occasions when coffins are dug up or resumed, perhaps in order to identify the occupant, scratch marks on the inside of the coffin are sometimes found, as well as torn shrouds, and sometimes the corpse is found sitting in an upward position rather than lying down.
It's a horrible scenario to imagine someone waking up whilst buried in a coffin, but my 'opinion' based on my interpretation of the evidence, is that it has happened.
There are also religious issues. If you believe in an eternal 'soul' or identity, then a person never really dies. His body just stops functioning and the 'person' either migrates to another body (if you believe in Reincarnation), or resides in Heaven or Hell (if you believe in the Creator God).
However, I'm not religious, but I accept that what is currently 'unknown' or 'not understood' is far greater than the combined knowledge of humanity with all his various scientific disciplines. The current hypothesis that approximately 95% of all the matter and energy in the universe is invisible and undetectable, even by the most sophisticated scientific instruments, is an example of the limited extent of our knowledge.
