whether that theory is true or false is really irrelevant to me, but I can see where the depletion of oxygen might cause one to be more agitated than peaceful. I have stood by the bedside of many loved ones as they passed over, and whether they saw a "light at the end of the tunnel" or not is also irrelevant. They knew and I knew that there was something better in store and the pain and suffering was over and many smiled. If a near death exerience has caused someone to repent and follow GOD, that is great and they can relay their stories to others that might need it, but I don't.<quoted text>
The oxygen depletion theory has been refuted by several neurologists. There is still much to learn about consciousness surviving after the neocortex (gray matter in the brain)stops functioning. The last book that I read involving this topic was written by a neurosurgeon who had a near-death experience. It is very interesting. I don't know what heaven is like but I am absolutely certain (faith) that Our Creator has more in store for us after we leave this planet physically.
From a medical standpoint, an individual who becomes acutely deprived of oxygen usually becomes agitated and combative (internal agitation, not related to an observable cause) and does not experience the serenity or recall vivid details most often associated with a near death experience. Science and the belief in God need not be mutually exclusive.
It is raining here now. Is the rain Science or God watering the earth? or both? Does it really matter?
