I guess it depends where you are at in life. Which one do you think you will benefit more from? Do you see yourself being in a situation where you will need to use the language a lot? Or do you want to continue to benefit your physical health more with the Martial Arts? Just depends. Personally, if I wasnt living in Japan I would stick with the Arts, but if I was I would stick with the language. If you cant use the language you will forget it.
