That doesn't explain why you like it.
We often can't justify our likes - just one of those things. I suspect some of us are rather more inclined to problem solving than others - because it is a surefire way of gaining something, whether that is knowledge or ability. I did learn long ago that one often does have to work to gain many things, and I'm perhaps more inclined to look towards those problems that I might have a chance of resolving rather than those without such, which is why I tend to leave the spiritual things aside. Perhaps I should blame my parents, especially my mother, since we had lots of those physical puzzles as children, and lots of books, although they were both just ordinary normal working-class parents and not inclined to much that might be seen as being intellectual pursuits.
