I don't think the readers realize she's NOT 50 years old. Chronologically, she'd be 50, but PHYSICALLY and MENTALLY, she's still in her 20's! She spent only a year or two inside the dungeon. Not 30 years. Time was slow for her.
Just think of it as if she time traveled to the future. That's the easiest way to understand that she's still young.
