It's worth reminding that we cannot be immortal. We can only live indefinitely. But the universe will eventually see to it that we will end. Most models of the cosmos say so.
Barring some discovery that allows us to hit the reset button on matter and energy every trillion or so years, time will end for us all, no matter how long it seems.
Well yeah, the universe being finite sucks as well. Maybe we can't ever change that, but that doesn't mean it wouldn't be better if we could.
Death sucks. It would be better if it didn't happen.
