Forum:Jewelry Bonney's Devil Fruit

It has caught my attention that Jewelry Bonney has a prety unique Devil Fruit ability. Her ability alows her to change the age of not only people she chooses but herself. So it is possible to argue that her ability allows her to extend her life. Could it be possible that she is the oldest living person in one piece( being able to rejuvinate herself using her powers)? WHILE I AM NOT CLAIMING THAT SHE IS A CITEZEN OF THE ANCIENT KINGDOM I AM  CONTEMPLATING  THE POSSIBILITY THAT SHE KNOWS ABOUT THE VOID HISTORY.
