I propose an experiment. You will give a meal to a twin. Someone else will be with the other twin far away and ask them what the other twin ate.
Which is the problem with much supposed research into such as telepathy. It seeks to IMPOSE what telepathy should do, not study evidence of what actually HAPPENS.
The presumption you make is that it is repeatable at will. Sensing death is not an act of will.
It’s exactly like me saying “ I’ll believe in relativity if my watch goes bavkwards” or “ I’ll believe in dark matter if my telly doubles in weight”
But The universe does what it does. All you can do , is observe what it does, you cannot impose what you prefer.. Some events are rarely repeated. Scientific process, which demands repeatability struggles with them, so science studies a limited subset of observation.
From what I hear, his conclusion is only that people with this experience had a dramatic change in their life. Darn right! They almost died. That would make anybody have second thoughts about how he is living his life. That doesn't prove their NDE was a real experience outside their body.
There you go again. A straw man based on conflating one type of experience with a wholly different type.
There is evidence of consciousness of remote places and events, whose details are such they cannot have been imagined. Providing fraud can be ruled out, the present scientific model has a problem with them.
