Human Magnet Effect
Why do people live in cities?
Look at a city from above — a million lights, ten thousand streets, people stacked in towers fifty stories high. Why would anyone choose to squeeze together like that when there's so much empty space everywhere else?
Turns out humans are like magnets that only work on other humans. The first person opens a bakery. The second person needs bread, so she moves nearby. The third person sells flour to the baker. The fourth repairs the oven. Each new person makes the place more useful for the next.
