One think we can concur is that each and everyone of us has hyperfixations, some have permanent ones, others have cyclic ones but it's one of the things that makes us who we are and makes as happy.

My hiperfixations tend to be related to media, a tv series, a book series or about medical cases/diseases, etc. My 5 year hyperfixates (for now) on flags, countries, capitals and car brands and brands in general.

I try to stay away from some hyperfixations that cause me too much anxiety like true crime and real disasters (stampedes, wars, earthquakes, etc)

What are yours? And feel free to share some knowledge!
