Challenges of a changed identity, What you could write about: 

I think the one of the most primary emotional relevance of the books that we read for English usually has to do with growing up, and many classics even fall in the category of growing up. I want you to think, if there was technology that could reverse age you, and people either methodically used for a study (and what others would know), and the affected adults, now children temporarily didn't know, given that they had the memories of an adult. How would they feel different? Maybe they could be put in a dire situation, as children, and those kids, because of some kind of magical chemical solution, mature emotionally faster, what would that look like, and how would that effect how intelligently they figure out the solution. There must be some bad consequences to it as well, because these types of experimentation on people and new products shouldn't have been introduced because of the ethical flaws. For example, those children could understand childish concepts with greater precision and speed, but because of maturing too quickly aren't ready for the heavier adult subjects. And also, they feel insecure and urged to understand very mature and inappropriate topics unfortunately, and when they encounter some truths of the adult world they can't emotionally handle it. How would this story go?
