OMG, thanks for that article. You see, it did affect my focus and concentration. I could feel it building up before I was called on to "center stage." All I could think about was the impending fart building up from the inner depths of my buttocks. Perhaps in allowing myself to become obsessed with the looming gastrointestinal disaster, instead of focusing on the bigger matter at hand, I failed myself and failed a higher purpose of kata. Never again will I allow flatulence to disrupt my inner peace during kata. Sincerely, BISON
