South Korean retirees find a 'playground' in daytime discos

In daytime discos known as 'colatecs', South Korea's retireees are finding a space to relax, exercise and have fun after decades of hard work. In the back streets of South Korea's capital Seoul, a new kind of club is booming. But this isn't the wee hours of a Sunday morning - this dance floor is packed in the middle of a weekday.These retiree dancers are young at heart and members of one of the world's fastest ageing populations.
