AP writes: "A friend of mine from work, Chris, is a practicing Catholic with 5 children. Before marriage, he was even in the seminary. He is very orthodox. He also happens to have a number of black belts in all sorts of martial arts. I have two teenage daughters and and a 11 year old son. I want them to be able to protect themselves, especially when they go off to college. Last night, Chris came over and gave us family Karate lessons. I thought it was wonderful. The stretching and exercising were great. He talked about the Eucharist. The only thing that was a little bizarre is that in Okinawan Karate, and I think other Karate, they bow when they enter the dojo. . .
