Elderly struck by dance fever at Monday afternoon discos

As the mercury outside plunges to - 10C on an ice-cold Monday afternoon, the dance floor inside Kukilgwan Palace is packed with gray-haired Korean couples moving to the rhythms of high-volume disco.

"I come here every day of the week, except for Saturday and Sunday," said 81-year-old Jun Il-Taek as he danced beneath the giant disco balls and brightly-colored string lights decorating the venue in central Seoul.

Jun was one of around 200 men and women on the floor - all engaged in the same, rather static, knee-bobbing dance routine, with the odd slow-motion twirl to liven things up.
