I believe one of the reasons why we have many questions about death, or we focus a lot on death is really the uncertainty of death. With life, we know it goes on. We are sure of that. We also take for granted that we wake up day after day. We take for granted our lives, and most today are not grateful or thankful for the life that they have or their loved ones. And so when death comes, it seems like the "finale", and we would like to know how is it at the end? We want to be assured of something that we don't know about, until it happens to us. And nobody has really come back and said, "death is like..."
If I were to hazard a guess, I probably think that death is like life and both form an infinite loop (life-death, life death). And it is needed for life to go on, just as life is needed by death to go on.
