Did you know a singer in Seoul broke the world marathon for singing?

SEOUL (AFP) – A South Korean housewife on Saturday broke a world record in marathon singing after crooning for more than 76 hours without stopping at a Seoul karaoke bar, local record verifiers said.
Kim Sun-Ok, 54, broke the 75-hour Guinness World Record held by Marcus Lapratt of the United States, the private Korea Record Institute said.
She started singing at 11:14 am Thursday (0214 GMT) and sang a total of 1,283 tunes before she gave up at 3:21 pm Saturday following her family's appeal for her to quit for the sake of her health, it said.
Under Guinness World Record regulations, she was given 30-second breaks between songs and five-minute breaks every hour. She was also barred from singing any song she had already sung less than four hours earlier, it said.
"My sister has had a very strong sense of determination since she was young. Once she sets her mind to anything, she finishes it," her brother, Kwang-Jin, was quoted as telling South Korea's Yonhap news agency.
The Korea Record Institute said it would submit video footage of Kim's feat to the Guinness authorities for official recognition as the new title holder in "longest singing marathon by an individual."
