South Korea is one of the countries facing the ageing problem. Women born in South Korea in 2030 are projected to be the first to have an average life expectancy of over 90.
A group of Korean women in their 70s finds new freedom in the "cheerleading team," which mixes cheerleading and aerobics.
The seniors say Cheerobics is a stress-reliever which makes them happy.
Cheerobics becomes a popular activity for South Korean seniors who are just retired.
