Death

From Hitchhikers Guide

Apparently death is the opposite of life and is what happens when you're laying down, not moving and apparently stopped. No one knows what death looks like or feel like. Mainly because they were too dead to tell us what death really is. I predict that death will be some weird stuff where you are moving around in some sort of black room, where everything is weird and stuff, cause death is apparently supposed to be weird and stuff. Nobody actually knows what death is truly like, even those guys who survive these things called "Near Death Experiences". Sure every experience may be different, but it's hard to tell what death is like, even me the guide does not know. Mostly we may never know what death means.
