"Martial arts are codified systems and traditions of combat practices, which are practiced for a variety of reasons: self-defense, competition, physical health and fitness, entertainment, as well as mental, physical, and spiritual development."
I guess it's hard for you to understand the value of physical health, entertainment, mental, physical and spiritual development. This is something that people in these boards should value a lot more, and that can have a huge impact in your life.
Sorry for the long reply, but your comment made me feel sad for you.
