Xu Zhipeng, a freelance computer graphics artist and Internet gamer, with his typical day's worth of food in his rented chair at the Ming Wang Internet Café in Shanghai, China. (From the book What I Eat: Around the World in 80 Diets.) The caloric value of his day's worth of food in June was 1600 kcals. He is 23 years of age; 6 feet, 2 inches and 157 pounds. He lives at his computer station, day and night, sleeping there when he's tired and showering once a week at a friend's apartment. His longest continuous game lasted three days and nights. When he tires of gaming at the café he reads fantasy books. ?It's nice to rest your eyes on a book,? he says, even though he's reading it online. China has more than 300 million Internet users?a number close to the entire population of the United States.
