Cheerleaders symbol of longevity

SAMCHEOK, SOUTH KOREA - Waving white pom poms in the air, dozens of grey-haired cheerleaders in matching red and white uniforms hop and skip to K-pop music that fills the practice room.

Halfway into their two-hour practice session, most of the elderly dancers are panting and sweating, but do not let their bad knees or back pain stop them from what they say is keeping them healthy and youthful.
