I have this quirk of mine were I love to learn about great woman/men of history.?

For example in my free time I like to read up or documentary/biography on the lives of people like our founding fathers,famous philosophers and artist such as plato Socrates and Leonardo . I also like activist and leaders like Gandhi and Nelson mandela. I even like learning a thing or two from world religions. Does anyone else have this hobby I guess you could call it? Do you think this is something weird? I'm 15 by the way...
