I'll say no one can truly know. Unless you are yourself immortal

If it's just you being immortal, loss of all family, and friends, and loss of new friends, rinse repeat forever. Eventualdieyoull watch society collapse and regrow (possibly), and the planet will die. Immortality is forever after all. Then you're left alone on a deserted dead planet. Electronics you have will eventually break and fade away to time. The sun will grow and die off, and it'll burn because you're immortal but still stuck on a planet that'll get enveloped, eventually. Living forever would be terrible unless it was forever until you died of something physical, just not age and illness.

Read this on the largest number every used in a mathematical proof.

Then ask yourself, if you think you could handle this number in microseconds let alone an eternity

Does yer dick still work when you’re like 150?

All the people trying to dissect you for science.

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

Man, you took it too real too quick

Watching history repeat itself.

If everyone gets to be immortal, imagine never being able to get rid of dictators. Putin's 600th won election.

People in the future wouldn't be allowed to have children, Earth will be filled to the brim with very old people and very few new ideas.

outlasting humanity and all its trappings
