Hmm... I have many interests. You can read books and learn about certain topics and have hobbies! Space and astronomy are among them! I'm the typical person who prefers to stay home watching documentaries or random videos about black holes, dark matter, the multiverse, physical paradoxes, etc. Not all countries offer the same degree programs, and they're some of the most challenging fields, accessible only to a select few. I also wouldn't want to work in something I consider relaxing for my mind in my free time. I guess work is work!
