I believe that mind, spirit, and body have to be equally trained and exercised. That is why I engage with science and martial arts, the latter since I was 10 years old. I am currently a black belt 3rd Dan in judo, have a long competition experience and practice regularly. As I have no teaching qualification for Judo, teaching in this context has not been consistent. Yet it happened and still happens frequently to support the growth of every member of my judo group.
I have a Shihan license in Ichi Gi Do Bujutsu, a Koryū encompassing Tenshinshoden Katori Shinto Ryu and Shino Rikugo Jujutsu. I practice regularly and teach for free Ichi Gi Do Bujutsu once a week, under the authorization of the Soke Shiigi Munenori. In case you are interested, you can check it out here.
