Do the elderly really become conservative and rigid from mere age, though? How much of that process is driven by declining health and feelings of alienation from modern society? How much by the belief that people of significantly different ages can't have meaningful friendships? I have a hard time believing that we'd see the same patterns if 20-year-olds and 200-year-olds saw each other on the metro every day.
