Conciousness in the Abscence of Life

I've been pondering this for only about 5 minutes, to be totally honest, but I thought I'd get it down in writing while it's still incredibly fresh in my mind.

I was contemplating the old evolutionary ways of 'survival of the fittest,' when I suddenly moved into the whole idea of consciousness. It's a proven fact that the human brain, which is the seat of consciousness, as well as humanity as an individual and a whole, is a biological structure, and as such, is subject to the universes fundamental physical laws. Thinking strictly in these terms, it would seem hard to really believe in the face-value interpretation of a spirit, especially one that continues to exist following the physical death of an individual. Now, to make myself clear, I am neither supporting nor condemning any religious or individual beliefs in regard to a post-mortem spirit; I am simply voicing my interpretation as it is at the moment.

It would seem, in a black-and-white sense, that when the human brain is dead, it's simply dead. That's all there is to it. As such, the consciousness of the passed individual is also destroyed. Interestingly, depending on the individual, it may not be as dead as one may believe.
In the sense that it has lost its awareness of itself, it is, or would at least seem to be dead, and many would argue that awareness of itself is what makes it conscious.

Let me stop dancing around the idea itself, and simply jump to the point.
For example:
There is a man who has decided to live his life to the fullest, as he sees it, and decides to go bodysuit-gliding through a part of the Andes mountains in South America, at a direct risk to his own life. Someone (or a group of people) decide to record it professionally and cinematically. The said gliding individual, after a heart-poundingly epic session of gliding, dies upon a rough landing due to a punctured wing. Regardless, the video is placed on the internet, and becomes incredibly popular, and as such, through the video, people relate to the conscious activities of the gliding man, and what he saw in the last moments of his life. I don't know about everyone else, but if I were to witness such a video, I would feel as if I would be glimpsing inside the gliding mans consciousness both at the moment, as well as a whole. That moment would give me a good idea of who he was and how he thought, as well as what and how he perceived. In this sense, his consciousness would live on not only in me, but in the millions of others who watched the video with an emotional maturity and understanding, regardless of the fact that he's dead.

Now, on the contrary, a young inward-looking individual who remains out of the public spotlight entirely, is at home at this bachelors apartment one night. He has only a few very distant friends, due to his self-imposed isolation. While alone, he chokes on a piece of food, and dies as a result. As soon as his consciousness disperses, it disperses into nothingness due to his remaining out of the public spotlight, and making it hard for the majority to ever understand, or ever get the chance to understand, what or how he perceived. His story would be very unlikely to be told anywhere, to anyone, due to the above reasoning's, and as such, everything about him would probably disperse entirely, and he would be largely forgotten, except as a vague memory by his distant friends. The only people that would be likely to remember him with any depth would be his immediate family; like his parents, or possible siblings, and through them is the only way his consciousness would continue past his death, providing they understood him well enough.

I'm honestly not entirely sure about any of it, but it's a interesting concept. Just thought I'd get it down on my blog, unlike my other in-depth philosophical thoughts I haven't got much of a chance to write about in the past few weeks.

Anyways, hope this was interesting for anyone who decided to read, and have a good night, Blue Planet.
