From 26 to 71.
This is the age range of the 10 new leaders that will be in charge of reforming the ruling Grand National Party.
The head of the ruling party's emergency steering committee Park Geun-hye introduced the new faces to the party's standing committee members on Tuesday.

Grand National Party] "I stand here today to ask for your approval on appointing these new leaders. I've worked very hard to recruit these people who are more than capable of carrying out reforms in politics. I hope we can start off with your positive support."
Out of the ten leaders, six are from outside the party including former presidential secretary for economic affairs, Kim Chong-in and 26-year-old founder of a volunteer tutoring program for underprivileged students, Lee Jun-seok.
Recruiting Lee was seen as part of the party's efforts, to improve communication with the younger generation.
The new leadership held its first official meeting following the announcement and pledged to make reforms that will best reflect the needs of the people.
Meanwhile, having selected nine candidates, the main opposition Democratic United Party, is gearing up to elect a new leader at next month's party convention.
