In my travels I have encountered many things...but do you know one thing that stands out above the rest?
Death.
It is simple to accomplish and yet impossible to reverse...why?
Soul?
Time?
It takes around 8 minutes for the brain to fully shut off after death...so are they still conscious in some way? And is it the same time for the soul to leave the body?
Pain?
Can they feel it?
If they were shot and died instantly is that the end? Or can they feel the pain for 8 minutes after?
The same with anything else...but what if the brain was damaged or destroyed, will there still be those 8 minutes?
Squished.
What if something fell on your head and completely squished your brain?
8 minutes?
Still?
And how are they so sure that there is 8 minutes of activity left in the brain?
Tests.
You run the tests.
