They have lived underground for so long that, without digitally-enhanced contact lenses, they are basically blind. They have grown so unused to exercise that they can barely lift themselves to a sitting position. In fact, they often wonder, why move at all? For them and everyone they know, work and entertainment both happen through computers linked directly to their brains. The world around them is in grey, ugly ruins, but they don’t care; the world in their minds is full of beauty and excitement. As for human contact, they interact frequently with each other’s avatars online. What is the best description of the emotional appeals in this excerpt?
