Personally, I'm not at all content with the idea of losing my consciousness. Not just because I've become accustomed to being alive, but also because I find it such a waste. All of that experience, information, the whole of my memories, all gone, dispersed to the four winds (Sorry,
Mr. Homn, I
am a bit of a romantic.

).
Sure, I won't be aware of it, the person whom I identify as me will not even care because he won't be there, and intellectually I understand that, but on a more visceral level, it does affect me. At the very least, I would like the human lifespan to be longer, even though it would still end.
The idea of "me" is quite an interesting one, I find. Every time I go to sleep, my consciousness is suspended and I don't engage in any form of actively chosen deed, but rather my mind simply turns on a sort of screensaver known as REM sleep, and my body breathes, both of which are involuntary reflexes as a result of human biology. When I am in this state, I am merely lying there and seemingly not doing anything.
The thought of dying does occasionally bother me as well as I'd very much like to carry on being a part of the world and contributing to it, but if I was being faced with the prospect of actually having to meet my maker (or possibly not, as a bus advert once told me) I think I might actually turn around and think about what the world is like because of things I've done.
Biologically, I've reproduced and so there are two other individuals genetically similar to me who will carry on walking the Earth after I've gone and carry on my lineage. However, I've also touched the lives of a lot of people, I hope for the better.
I've taught quite a few students and given them my own personal perspective on things, I've helped friends out with personal problems and on a wider level I've contributed to charity and done charitable works in order to try and make the world beyond me a nicer place. I hope that all of these things will carry on after I've gone as well, so that something I've done will carry on doing good long after I've ceased to be able to do them.
Even after we've moved on from the world, we leave behind an impression on it physically (through a very, very tiny increase in entropy through heat exchange, etc) and in the memories of others and how we affected their lives, hopefully for the better. I find that quite comforting, as even if I disappear from the world tomorrow, our presence in the world has changed it forever and permanently, even if it is in a small way and our thoughts, actions and values will remain with the world long after we have physically parted from it. Even if there is no God, the possibility for something of us to survive after death is nonetheless there in the world.
