No interest in the world

(29M) As the title suggests, I just don't have an interest in the on goings of the world really. Travel doesn't interest me, going out doesn't interest me much, events don't interest me, people in general don't really interest me. I'm a homebody through and through but I feel like even then I should have an interest in something. I've been single for years now because of my lack of interest. Just wondering if anyone else shares a similar experience. Not sure if there's anything I can do to even change it or if I'll ever find someone to be with as I am. I just don't have the desire to make a massive change alone honestly.
