I was asked this question last night ( If I grew up with judo and karate why tkd now), by reply was it is a extremly effective way of self defense and conditioning. Beside my kids love all the aspects of TKD as so does my wife. As everybody that knows my post my oldest has a dream to compete in the Olympics who knows!!!! And for us this has become a life over the last 18 years, so my question to everybody else why do you study TKD??? God Bless America
