One is 'Logan's Run'. In this story, people are not allowed to live past a certain age, and old age is seen as something to be eradicated. The main character, Logan, is a 'Sandman' who hunts down those who try to escape their fate of termination at the age limit. Another is 'Do Androids Dream of Electric Sheep?' by Philip K. Dick. The concept of old - fashioned values and the passage of time, as well as how age affects the characters' understanding of the world around them, is explored in this complex work. The old and the new, in terms of both technology and human nature, are contrasted.
There's 'Station Eleven'. It shows how different generations, including the older ones, cope with a post - apocalyptic world. The memories and skills of the older characters are important elements in the rebuilding of society. Their age - old knowledge of things like farming, medicine, and basic survival skills become invaluable in a world that has been stripped of much of its modern technology. And in 'The Left Hand of Darkness' by Ursula K. Le Guin, the concepts of age, gender, and identity are explored in a unique science - fictional setting, with the older characters having different perspectives and experiences that shape the story.
