You are an idiot. The brain will survive just a few minutes with no oxygen but 10??? Show the evidence of your claim.<quoted text>
The brain takes much longer to die than the body, when beheaded the person remains conscious of all activity for up to 10 minutes, of course there is nothing to move the muscles due to no blood, by the time the brain fully suffocates. Takes even longer if the brain is still attached to the body, not a pleasant thought, but then, that's why there is a release of a strong hallucinogenic once the brain thinks it's going to die. We can explain NDEs very well, we know more about those than dreams even. Though we know what causes dreams, the nature of the imagery is still somewhat perplexing sometimes. Either way, your NDEs are not spiritual in any way, simply a mechanism that evolved to make death less horrible.
The brain requires 20-25% of the bodies intake of oxygen. Take away the oxygen and it dies rather quickly.
Again you claim 10 minutes. You need to show evidence that supports and makes your claim true.
