Growing old disgracefully

The Old Man at the End of the World may be full of zombies, but the protagonist is an 87-year old man who finds himself unwittingly thrown into the apocalypse on a sunny Tuesday morning. Readers have a great fondness for older central characters. Through their eyes, those of older generations may well be inspired to grow old disgracefully (something we all desire, right?) and people of younger generations can see the world in a new light.
