Most NDEs experience very pleasant sensations. I've heard that most do not want to "come back."

Meanwhile many dismiss the experiences as brain chemical induced events at time of death to ease the fear and make death more tolerable. Nothing more.

I have always wondered if that's true then why? We evolve through many generations in order to survive. What would be the reason for any experience at time of death except to be clicked off like a light bulb. What's the point? if there is nothing after. Death has nothing to do with evolution.

It doesn't take a lot of googling to find that near death experiences have been researched by real scientists.

Why not?

You assume the brain is designed to trigger a pleasant sensation when death comes. It could just be a random byproduct of the brain getting killed cell by cell. Kind of what happens to my harddrive when running several read/write operations and just switching it off.

Anyway, I'm sure your questions, or our questions, will be solved eventually. On way or the other.
