I'm not pretty young but I like anime. In Japan, If a middle-age people say I like anime, people may think that it is a bit childish. Some foreigners may be said that age does not matter about your hobbies. However, some Japanese connect to something with age.
As a matter of fact, Im a not a super big fan of anime but I often have been watching an anime than a movie recently. My favorite is Demon Slayer: Kimetsu no Yaiba, Yowamushi Pedal, Kingdom, and Naruto.
I also like historical drama anime, for example, Onihei Hankachō but I think historical drama anime isn't popular for foreigners. All anime can watch via Netflix but I don't know those animes whether with English subtitles.
