Learning Japanese at the age of 30 definitely bent my brain in new and interesting ways. Certainly when communicating, it made me realize how much of speaking is actually stringing together groups of words to convey meaning and way less about using some perfect syntax or grammar. The whole backwards grammar relative to English also was pretty new and challenging.
As a native English speaker currently learning Japanese I love just how logical it all is. I'm not sure if it's because I'm from a software development background but I'm finding it so easy to learn.
As you suggested in your comment, it's a whole different way of thinking.
