Everything we have witnessed that arises also passes away. Every living thing, every dead thing - even stars and planets - arise and pass away.

I feel it’s the ultimate hubris to think we can cheat death.

Moreover, why would you want immortality?

Many books of fiction and poetry discuss the curse of immortality.

Here are a few:

The Immortal, Jorge Luis Borges (1947)

A man discovers a source of immortality, but eternity eventually destroys the significance of individual experiences. When everything can happen infinitely, nothing feels particularly important.

The Mortal Immortal — Mary Shelley (1833) - also wrote Frankenstein

A man drinks an elixir and lives for centuries without substantially aging. He watches his wife grow old and die, and becomes increasingly alienated from humanity. Shelley focuses on loneliness and the psychological weight of endless time.

All Men Are Mortal — Simone de Beauvoir (1946)

An immortal man lives through centuries of history, relationships, and political upheaval. Gradually he discovers that even extraordinary achievements seem meaningless when time is unlimited.

The Makropulos Affair — Karel Čapek (1922)

A woman lives more than 300 years through an elixir. She retains her youth but becomes emotionally exhausted, cynical, and incapable of finding pleasure.

There are more. Sure, these are fiction. But use your imagination. Why would you want immortality, even if you could retain perfect health indefinitely?

Well, accidents. Inconveniently close supernovas. Something is likely to get you eventually, some few millennia later.
