For me, being an atheist makes dying palatable. It's natural to die and it's necessary. Without death there would be no such thing as evolution and we wouldn't exist. My religious friends are much more frightened of death than the atheists I know. They think a major drama is going to begin when they die. In short, they're afraid of getting a bad grade on their lives and being cast into an eternal hell (by their loving god; gotta love that). This means fear and death are entwined in their lives, unnecessarily of course. And many of them are afraid because deep inside, they fear their beliefs are nonsense. All the above cause them to have a terrible foreboding about death. It's sad, really.
I don't share these feelings. Death seems both inevitable and fine to me. I even have this notion that dying probably feels great, like going to sleep when you're totally exhausted. We have to focus on living because it's the only thing that matters. Death is kind of irrelevant. Why think about how it will "be" when you're not here? The obvious truth is that you didn't mind not existing before you were born, and you won't mind it again when you've gone from this Earth. Simple and easy: nothing to fear. Enjoy your long life rather than worry about the last three seconds of it. Makes sense to me.
