Death is one of these mysterious of life we can't quite wrap our head around. What happens after we die, I don't know and frankly I'm not entirely sure I want to know. However, to me it's fairly obvious that something inside a person disappears at death, if this is the soul being liberated or not is up to debate, but there's a blank stare from the dead that is... lifeless. The eyes of a person who is alive have a certain glow to them, which disappears instantly at death. It's as if the "glow" itself is dragged out of them and you're looking at an empty shell. It's a very strange sight...
Death could be many things though, the end of us, the end of the physical us, either way you look at it, it is the end of something. The end of our excitence here in this world. If there is a life after death I highly doubt that we'll even remember this life, or even care about it. If I'm going to think about it from a "soul" perspective I imagine the soul being energy released into the universe, if we have a conciousness at this point then I would imagine our understanding of the universe, life, death, the world, would become unrestricted. Which would in turn lead us to see a bigger picture which does not involve the "physical" world.
If death is not the end of life, and theres a larger reason for "death" aside from the fact that we'd overpopulate the earth in a century or two, then it would stand to reason that this life has some sort of meaning as well. If this life has some sort of meaning then shortening it would be foolish, but I digress.
My religion teaches me that death is not the final "end", my experiences teaches me that death is the final end to something, but that something happens at the moment of death I can not hope to understand. Knowledge teaches me that death is a necessity, while my instinct of self preservation would do anything in my power to avoid it. It's all very compliacted...
