In 'The Age of Adaline', a key element from the true story is the central concept of a person's body not aging while the world around them progresses. This gives rise to her complex relationships as she has to keep reinventing herself in different decades. The movie might have drawn from real - life stories where people with unique conditions face difficulties in fitting into society. The idea of her love life being affected by her non - aging state is also an important aspect that could have been inspired by real - life tales of those who are different from the norm.
