If they really wanted to do that, yeah. They could. But they don't want to do that. They spend most of their time kicked back, having sex, relaxing, having sex, farming, having sex, working, eating, having sex, going to museums, having sex, and oh. Before I forget to mention it, "having sex."

That's according to information found in all the books(much of which is translated here on the wiki, though you have to hunt for it).
