Whats a really random topic for an isearch paper?

I want something fun and interesting. I have already thought of two prompts i just need a third. Here are my other two:
What are the effects on a person that has undergone physical and/or medical trauma?

Is body language a true indicator of emotions and is it a reliable way to understand what people are feeling?

Im interested in dinosaurs, psychology, medicine, human behavior, societal trends

I thought about something that had to do with how middle children vs. younger children vs. Oldest children are affected by their position in the family and how they relate to people because of it. IDK ! help
