It is often mentioned how two diverse games have their origins in India. Kung-Fu (through Bodhidharma), JuJutsu (India's wrestling & grappling), are martial arts documented to be something developed out of India's traditional combat styles.
Also, Chess is well-documented to be a game played by royalty in ancient India. The known, recorded history of chess goes back at least to the emergence of a similar game, 'chaturanga', in seventh-century India.
Mind and body are both thoroughly tested in a martial artist, with or without chess.
You should also look forward to participating in Kata Team tournaments just as chess players have Chess Team tournaments -- so as to be capable in teamwork while also developing individual fighting skills.
Keeping that in mind, here is a humorous meme from the internet.... the legendary Chuck Norris ready for combat.
