Firefighter here. I was reflecting on a fatality I attended recently. My thoughts wandered to how a body looks like it is 'just matter' in a way that a living thing does not, even when sleeping. Previously I assumed this observation was just something to do with traumatic death, but this person seemed to have died peacefully and the same, 'absence' of something was obvious.

I'm not a religious person, but it made me wonder if there actually is something that 'leaves' when someone dies (beyond the obvious breathing, pulse etc).

I'm not looking for a 'my holy book says', kind of discussion here, but rather a reflection on the direct, lived experiences of people who see death regularly.
