Being asked your birthdate in order to view a game on Steam, and the year dropdown not going back far enough.

Having to keep creating fake identities to prevent people and governments from finding out that you’re immortal. That would be a massive pain in the butt, especially in a world where mass surveillance of the population is common.

People are commenting ‘fates worse than death’ and ‘being made into a labrat by the 1%’, but really, if you have infinite time to just do stuff and you can’t be killed – And you don’t somehow squirrel your way into a position of power then what are you even doing with your time and immortality, oomfie?

The loneliness part is also questionable. I know OP said it’s overly done, but I also think it’s just wrong. If you’re an adult you’ve had people in your life die before. It sucks. You miss them. But then you move on. And you meet other people. You’ll still go “:(” when you think about the person and such… But life goes on.

And that’s just life. It doesn’t get any worse if you extend it longer – If anything it gets better. You might have lost your beloved today, but you have another dozen lifetimes to heal your wounds and meet someone else and fall in love again and (…)

So here’s some lower-stakes, frustrating inconveniences of being immortal:

• Your favourite fashion? It’s not just out of fashion. It’s so out of fashion it is now considered ‘historical costuming’. You can no longer find any articles like it at all. Because the only people even trying to recreate the techniques are costuming nerds and theater people who always exaggerate stuff
• You got a song stuck in your head. It is either from before recording was invented, or any recordings of it that existed are too old to be reliably listenable. You have a song stuck in your head.
• You used to really enjoy a job you did. That entire career path is now obsolete. As per the first paragraph of my post, if you’re immortal you have probably snuck your way into the upper echelons of society at some point during your infinite time… But like. You’re bored. You loved being a Court Jester, now there are no Court Jesters.
• Actually tedium just in general. Sooner or later you’ll run out of new things to try, because you’ll have done everything that even remotely caught your eye already. So what the fuck will you do with your time? You’ll eventually just get depressed and not do anything.

All the comments assume everybody else isn’t also immortal. I forget the title and author but there’s an old sci fi story (or novel?) about a future where everybody lives for centuries, and they’ve found that the brain only retains a certain amount of experience. They have long careers, get tired of doing whatever, re-educate and do something else, or even have multiple families they eventually forget about. A couple of the characters are surprised to find out they used to be married like a century earlier. To me that seems vaguely like reincarnation, and I kind of don’t hate the idea. I really don’t see any downside to that scenario, or even just going on forever.

People are focused on having regrets and negatives that last forever. But buck up li’l camper, you can learn to move on from stuff. And I say this as a dad whose daughter had cancer at age 10 (she survived). It was hell and I wouldn’t want to live through that whole period again, but I don’t consider it a reason not to want to live forever. The trick is to learn how to cope with these things and not let them outweigh the good experiences you have.

Depends on the type of immorality. Do you continue to age? If no, what age do you stop? Eventually the universe will die. So what happens to you then?

It might be fun for a while. Maybe even a long while. But that fun will be gone in an instant compared to the trillions and trillions of years you will float in a dark dying universe of nothing.
