Do you like to read really old literature because...

By old literature, I assume you mean the classics?

Those are the books that have stood the test of time. For each and every one of them (well at least after the printing press), hundreds if not thousands have been delegated to the dustbin of history. They have survived on their own merit because they are good. And I mean really good.

And yes I read them I'm currently reading several old Norse literatures as a part of some courses I'm taking at the local University as a hobby. Higher education is (almost) free here in Norway, so I usually take a course or two every year in whatever interests me. I also read a ton of modern books.

And yes they are very good, trying to read them in the original Old Norse however still eludes me.
