An 80-year-old man who has not slept for six decades

Every now and again, if he drinks enough rice wine, Ngoc is able to switch off his brain long enough to get one or two hours of sleep. He regularly lies down to try and get some rest, but his eyes rarely close. The rest of the time, he's up and about. While everyone else is catching up on their rest, Ngoc passes the time by working and making rice wine. He said he doesn't get tired in the same way most other people do, though he gets boosts of energy from drinking green tea and rice wine.
