INTERVIEW WITH THE AGESHIFTER

This story will describe an extended Question and Answer session between a professional reporter and a mysterious individual who may or may not really exist.
Somewhere in the world, there is a person who looks normal but has a secret ability.
She can make herself grow older or younger and appear any age she wants. Whenever she wants, as often as she wants, as fast as necessary. She really does get shorter or taller or lighter or heavier whenever that happens.
There have been stories and legends such persons exist, and claims something like that has happened to other people. Perhaps even to you?
The questions that were asked in this interview were inspired by another novel published online that feature a very complex character. This is a simpler character, who still lives an extremely complicated life.
