I beleive (at a minimum) that long after I die, the physical usiverse will cease to exist (either by the "big crunch" or "heat death"). At some point in time in the very distant future the universe will exist again, I'll be born and live again. Remember from a literal standpoint, there is an infinite number of you's living in the "forever timespan"...
Of course, I an hoping for either benevolent Aliens or friendly Fairies to scoop me and my family up and will live forever on the wings of energy...
