Kenny Myers, a child care expert from Texas, has a great article at http://www.kenneymyers.com/blog/10-reasons-martial-arts-benefits-kids/. Kenny is not a martial arts instructor or school owner, just a child care expert, so his article focuses on children. However, in many respects I would go so far as to say the title should be "10 Reasons Martial Arts Benefits Everyone".
Without reposting his entire article, the 10 reasons he lists are:
During the summer break, I would travel just as I had as a youth. I had no money, so I hitchhiked across the country, seeking the Buddhist temples, so that I might extend my knowledge of Zen, Tao, and Confucianism. These three had come through China to Korea. Confucianism of course started in China. Zen came there from India, but through China first. Buddhism became very strong in Korea.
The college I attended trained its students to enter the Navy or the Merchant Marines. Even though I was on that course, I wanted to fulfill my military duty. So in 1967, I joined the Navy. Korea was very poor at the time, and we had just ended a horrific civil war. Military duty was brutal. The Korean military still used the Japanese techniques for training the recruits. Often, they would be killed during the training, it was so harsh. Technically, the south was still at war with the north. Entering the armed forces meant you were most likely going to war.
One summer, when I took off from school, I travelled the country to visit the masters, grand masters, and spiritual leaders I could find. In 1966 I visited one famous spiritual mountain, Gyeryongsan Mountain. Gye means "chicken" and Ryongson means "dragon". Thus the mountain was called Chicken and Dragon Mountain. On this famous mountain was a temple that had been there for 1000 years, called Kapsa. Kap was its name. Sa means "temple".
In my eagerness to study martial arts, I often visited other schools to learn from the masters and students there. On one occasion, I visited a school down by the harbor. Pusan is a harbor city, famous at the time for its smugglers and gangs. This school was on the second floor of a building down by the ocean and was affiliated with a gang of smugglers. I did not know this at the time.
Many Thanks to ALL of those who make this event possible year after year, for the past 40 years, and we look forward to seeing you year after year, making history together in the world of Martial Arts!
