Between March and December 2005, myself and 2 sidekicks, Anna and Mel, subjected ourselves to three (sometimes four) times a week tuition in taekwondo. Our mentors were Kwan Jang Nim (Grand Master) with his 7th grade black belt and 30 years experience, and Sah Bum Nim (master) a lowly 4th Dan of 10 years black belt experience. Our Wang Ho dojang (King Tiger gym) is, KJM proudly tells us, the best gym in the county, and affiliated with Kyong Hee University, the best taekwondo university in South Korea. Our two masters for three students education rapidly became a way of life, and a bargain one at that for fifty quid a month.

Learning sonnahl chigi or 'knife hand strike', or if you'd rather, 'neck chop'

Sparring with black-belted Hyong: 'older brother' as the Korean system of addressing elders and seniors dictates. Oooh! my ribs were tender that evening
Proudly showing off black belt status with Sah Bum Nim ('master') of many years black belt experience, yet only 25-yrs-old (and he delivers a mean, ceiling-reaching, flying cartwheel, 360 degree turn kick)
