Superpower
It seems like with this little girl, superpowers are very much a real thing with her and she is unable to feel any pain. She actually has a missing chromosome that gives her this incredible ability to do all the things we mortals have to live with each and every day.
Things like sleeping, hunger, or pain are completely foreign concepts to this lucky young girl. Imagine never feeling the need to sleep or eat, all the time you would save cooking meals or the hours of your life you spend with your eyes closed. You could accomplish so much with all that extra time.
