Cancer. So much goddamn cancer. It doesn’t matter what kind of immortality you have, you WILL get cancer. Repeatedly. Over and over. Forever.

The disappointment of experience winning lifetime supply of something but that would eventually turn into a lie

Wage slaving never stops

Family meals that take 3 restaurants No retirement

Loneliness. I think being immortal would show someone what true Loneliness is

If we’re talking magical immortality, as in you can’t die, at all. Then the fact that however much enjoyment and experiences you get while the universe still exist, it will be followed by an infinite stretch of nothing after the heat death of the universe.

Nobody is answering the prompt lol. Everyone says all of this shit all the time.

You live long enough to never feel at home. Sure the loneliness sucks or whatever, but who do you root for at the football game?

Having to buy new shoes for the rest of eternity. You know how much work I’ve literally just put into finding shoes that 1) don’t suck and 2) aren’t made with slave labor? It’s impossible. Drives me insane. I’d found my own shoe company once I become immortal rich just to fix that problem alone. Maybe other stuff too we’ll get there

I suppose on that note: it seems like a really bad idea to become a public figure after a while. Like you obviously don’t want your immortality found out. You have to have like illuminati power before that point though, but it could happen at any time. Like if something happens and you become a news item (i.e. helping someone out and a video goes viral online). Not saying everyone is all that close to going viral, but over a sufficiently long lifespan you’re effectively rolling that dice a lot.

i think that experiencing all the things & people i care about would be the worst of it.

either that or seeing us repeat history over and over again as a society complete with all of the indifferent cruelties it entails and studying it, but ignoring it anyways

If you have epilepsy or Parkinson’s or MS, you’re just going to likely get worse forever.

At some point, our sun will go supernova and you will end up drifting through space.
And all your life before that point will be less than a blink of an eye compared to the time that follows:
Trillions and trillions of years until the heat death of the universe.
And even that time will be less than the blink of an eye compared to the eternity afterwards, when you drift through a black void without any stars.

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.

A lot of ways to die are excruciatingly painful, but you die, so you don’t live with the pain. If you end up in one of those situations and don’t die (because you are immortal), I imagine the psychological impact of the pain without immediate release could be enough to completely break you, mentally.

Everyone else in your life that isn’t immoral (if you’re the only one who is) dies eventually, so every time you make a friend or start a family, you do so knowing that you will have to watch them all die someday.

Life will pound you into an uncaring jaded disinterested unloveable husk of a being after too many emotional scars from losing loved ones, too much of seeing humanity make the same mistakes, and too much watching the knowledge you gained turned irrelevant.

Or, life will beat into you an uncanny ability to converse and relate to others, even if fleetingly.

Watch The Man from Earth.

If you’re injured and you survive with the scarring from said injuries. Well, good luck because you’re now going to wear those and wish you had died from them. If you’re incapacitated or amputated? Gotta live with that for years and years.
