Near Death Experience Research

I've found an article online that discusses Near Death Experiences. And along the lines of the direction of the class, the article talks about a scientifci approach to understanding Near Death Experiences, much like how Lane speaks of physics and chemistry being foundation of religous diversity.

So Lane's discussion of near death experiences (nde's) are biology's
last ditch effort to keep us alive. My question is, what if we do not
get the chance to have these near death experiences? How come some
people experience these nde's, while others don't. Do only 'religious'
people get these nde's? Well, Lane did explain that the object at the
end of the tunnel, whether it is god or a bicycle, is what draws us
back to life. Almost as though we had some unfinished business and the
object at the end of the tunnel reminded us of that. But let me set
up a scenario, there are two populations of people. Population 1 is
100 percent deeply religious, consisting of Christians, Buddhists,
Hindus. Population 2 consists of people who take no part in any form
of religion. Statistically speaking, will the two populations
experience the same number of nde's?
