I learned about cars, robots, food, soap, toys, cigarettes, sweets, fountain pens, timber, fish, newspapers, oil, wine, nuclear fuel, the army, the police. I visited hospitals, refugee hostels, sweet factories, oil refineries and nuclear plants, was taught how to drive a Land Rover through a river, how to fire the cannon of a Centurion tank and have sat quaking in a police car during a high-speed chase. I learned how the insurance and banking systems work, as well as about human rights, our plundered environment and the scandal of places like Bhopal.
