What does one do for 8 hours a day in class? I could not physically manage an eight hour class at the same intensity as the one or two hour classes I'm use to. I guess I mean, is it the difference between sprinting and marathon running? Eight hours could make a really good martial artist, or a really bad one, depending on what and how you practice. I've seen the Korean demo teams do some fantastic board breaking, choreographed fights, and team stuff over there. But I've seen the same team do forms individually that were no different from the average stuff here. And I've seen individual stuff from Europe and the US that is just as good or actually better than the individual stuff from Korea. And for some reason, almost every South American I've met is a competent in full contact sparring. (Of course, their economy is different from ours as well, many of them trained to fight for money, or make a name for themselves for teaching credentials.) As for North Korea, they have an fancy marble building dedicated to tkd, complete with stadium seating, and a mechanized floor that rises to create a stage. In his latter years, I believe, General Choi oversaw training at that facility. The students there actually trained for a living--it's their job--Although I'm not sure what they are suppose to do with their taekwondo skills, since they can't open up their own school, compete on a tournament circuit or leave the country. But it's better than starving to death waiting for seeds to plant in the empty fields. I'm not saying it's better to train here. But I do think it depends on who your instructor is and who you are. Not everyone is willing to train hardcore for even two hours a day, even if they can find a competent instructor. Quality vs. Quantity holds true even for training time. (And I would rather live here than there any day--I like ice in my drinks, milk, chocolate, flush toilets, piped sewage, and air conditioning.)
