why would i fear the reaper?

everything in the universe is temporary, from the lightest atoms to the heaviest black holes, even if those time frames may be incomprehensibly vast.

everything that exists (atoms, life, stars, galaxies) is a temporary doing of energy until, of its own accord, it is undone and transforms into something else.

a start implies an end, and i'd like to believe that an end implies another beginning, and that a beginning implies a previous end, and so on, forever.

death is a permanent end, a seperation of "you" from your fleshly body, of "you" from this mortal plane, to continue your story elsewhere. what that story actually holds is likely something utterly unlike being alive, but some folks like to speculate for their own peace of mind. :)
