Goin back to martial arts, I practiced Tae kwon Do from age 8 to 25. Was highly involved in competition. Was ranked third in the nation for some time in the fly weight division. tried out for 92' and 96' olympics, but lost in quarterfinals. Tae kwon do has helped me tremendously in tree climbing as far as flexibility, and most of all, my work ethic. I would highly recommend any form of martial arts to tree workers. Tried to make a come-back a few years ago, but tore a meniscus in my right knee. Had to choose between work and comp. So I hung up my hogu for spurs.
