I fully accept the fact that one day, I will die. A matter of fact, thinking about it makes me smile, so I voted the last option. Not that I'm suicidal, on the contrary I have many many plans for my life and so many things I want to do (hey I'm young so I've got plenty of time). It's just that I realize that death is unavoidable, and I understand the true meaning of things in that EVERYTHING is impermanent, including myself.
The thought of everything being impermanent is on my mind every day and it comforts me, and helps me get through the best and worst of times. When I'm really happy, I know that feeling is impermanent and I know it will end, but I don't let that ruin the happy moment, it enhances the moment, making me enjoy it to the fullest of my ability. And when I'm sad, I realize that the feeling is impermanent, and that the sadness will go away, and I will once again be happy. Often as soon as you can acknowledge your sadness will not be forever it makes it go by that much faster.
Also if you can't tell already I'm Buddhist so I believe in rebirth, and I know that in the last moments(whether it being half a second or minutes) of life you actually stop feeling pain, and things become clear, and you are freed from the burden of this body. As Doer said, there is only the present moment, so simply focus on that, and enjoy your beautiful life while you have it.
(Sorry for going off on a tangent in the middle there I can't help myself sometimes)
