My dojo is not all that fancy, it's kind of a rustic affair that will be adequate for only me and another person . . . that's abut it I am a retired builder/carpenter and am building it myself on the cheap in my woods. anyways I've now read through the entire thread and IMO it seems that if you take martial arts as a sport, working with various age groups makes sense . . . but otherwise? Naaa I don't want to teach my grandson pressure points, killing/maiming techniques, etc. . . . and as we all know the martial arts started as a warriors way to defeat the enemy, not just to win a match (this is the more modern approach I believe) Right or wrong doesn't seem to be the question . . . what are you wanting to accomplish does . . . my approach is dangerous and drastic and no place for kids. The streets around here are mean so it takes an above and beyond mean to counter them. Ever hear of the game the called 'Knock out?' . . . . . From Wikipedia, the free encyclopedia (October 2011) Knockout, also known as the knockout game and knockout king, is a violent activity played by teenagers in which they attack an innocent pedestrian in an attempt to knock him or her unconscious with one punch.[1] The game can result in serious injuries or death for its victims and corresponding criminal charges for those playing it. [edit]Cases involving teens playing knockout The knockout game typically involves Black youths specifically targeting White victims for assault. Cases involving teens playing knockout come to light when extremely serious consequences result. In one such case, in 1992, three teens were charged with assaulting an MIT student while he and a friend were walking near campus. Prosecutors said that one of the teens stabbed the student through the heart, killing him.[2] In another case, a St. Louis, Missouri teenager and his friends allegedly attacked a couple as they were walking home from the market. After one of the teens struck the man, he hit his head on the ground and ultimately died in the hospital.[3] Both cases involved immigrants. The MIT student was Norwegian and was chatting with a compatriot when he was killed. The victim in St. Louis was a Vietnamese immigrant that was walking home from the Vietnamese market with his wife. Although authorities are unsure whether immigrants are targeted, the fact that immigrants are victims often makes other immigrants in the same area feel more at risk. [edit]
