What is the story like of a science fiction about a man who lives forever?

According to my knowledge of online literature, there isn't a single novel describing a man's immortality.

Jules Verne, although from an earlier era, has works like 'The Time Machine' that have influenced forever young adult science fiction. Ray Bradbury also has some stories that can be considered in this genre. And of course, there are newer authors like Marie Lu, who has written works that appeal to young adults in the science fiction space. They all bring different perspectives and styles to the genre.

The man might have a near-death experience and then encounter strange phenomena or beings that change his life.
