I am an astrophysics phd student, and my hobby would also be astrophysics. And I love reading, especially translated classics from different parts of the world. I collect books, and my career allows me to travel a lot- so I collect postcards as well. Another strong I interest I have is music- all kinds of rick amd roll. I am a huge Black Sabbath fan, also pink Floyd, also 200 other bands. I write as a hobby. Recently I have been thinking it would be amazing to send these thoughts with a stamp to somewhere else in the world, and get a reply.
