The grandfather recounts how much the world has changed from when he was born, listing many technologies and social norms that did not exist in his youth like television, vaccines, credit cards, commercial jets, washing machines, computers, cell phones, and instant photography. He notes how respectful interactions were between men and women as well as children addressing all adults formally. The grandson jokingly guesses his grandfather must be over 200 years old to have lived without all these modern things, but the grandfather clarifies he is actually only 60 years old, highlighting how rapidly the world has advanced.
