Also kind of a trope. It's a minor plot point in Sandman. Morpheus and someone else were arguing about immortality and how eventually we would all tire of life.

Also kind of a trope. It's a minor plot point in Sandman. Morpheus and someone else were arguing about immortality and how eventually we would all tire of life. So they grant a random guy immortality for as long as he wanted. Every so often, Morpheus checks up on him to see if he's ready to die yet. And he never is. In good times, he's enjoying it too much. In bad times, all he desires is to change his fortune.
