I’ll start off with one, Being upset about a breakup that happened hundreds of years ago.
Edit 1:
- Heath death of the universe, Death of the sun, etc, does not count. I feel like focusing on this is an overused point.
Edit 2:
- Loneliness does not count. I feel like we all know immortality means you’ll miss people and lose them.
Forgetfulness. Think how forgetful people get after having lived a normal lifespan, now go for a few thousand+ years and you’ve probably forgotten whole centuries of your life. This is actually the premise of a solo journaling game Thousand Year Old Vampire, you have to cross out and forget memories as you progress through the game, just forgetting whole parts of your life.
There’s a Doctor Who episode with that idea in it too, the Doctor saves a girl in Viking times but brings her back forever, and when he meets her in mediaeval times she has a whole library of books that are just her memories that she’s written down over the years.
What episode?
Actually it was a two-parter, S09E5&6 (of the reboot), called The Girl Who Died and The Woman Who Lived.
Here’s a clip of the relevant bit!
