I think you need to be more specific, "other field" can mean anything.

Have a look at "Ask HN: Do you recall any book or course that made a topic finally click?" https://news.ycombinator.com/item?id=33593631

Find interesting things? HN helps.

Otherwise, there are no fundamentally uninteresting things in the world and everything a person can study will add to the depth of their knowledge.
