* When I visited Japan, I saw this strategy save a woman’s life. Her young son stepped onto the Shinkansen, one of Japan’s famous bullet trains that travel at over two hundred miles per hour, just as the doors were closing. She was left outside on the platform and jammed her arm through the door to grab him. With her arm stuck in the door, the train was about to take off, but right before it pulled away an employee performed a safety check by Pointing-and-Calling up and down the platform. In less than five seconds, he noticed the woman and managed to stop the train from leaving. The door opened, the woman—now in tears—ran to her son, and a minute later the train departed safely.
