SAN FRANCISCO—Despite having no access to personal entertainment technology or media stimulation of any kind, 33-year-old Jeff Vali somehow withstood his entire harrowing 30-minute train commute Friday. “I wasn’t scared at first, but I started freaking out when I fully realized what was happening,” said a stunned Vali, who told reporters he had dashed out the door and left his iPod on the counter. “I still had my Kindle, but it went dead last week and I forgot to charge it. I tried to keep calm by reading the newspaper of the guy standing next to me, but I couldn’t get close enough to make out more than one or two big headlines. Even the ads on the train were all boring community college stuff. Eventually I realized I was going to be trapped with nothing but my thoughts for the next half-hour. It was horrifying.” Vali told reporters he managed to survive his ordeal by humming “Goodbye Yellow Brick Road” and sifting through the contents of his wallet.
