I study kyokushin in memphis, tn. when i was a white belt black stripe, i came home from church early, and 2 guys were standing outside my fence. as i parked the car i noticed they walked off in a hurry. I went inside the fence and decided to walk around the house just to check things out. there was 2 more guys stealing bicycles out the yard. i walked up and asked them why were they in my yard. these guys were both teen agers, and much larger than i was. i never thought that they would try to attack me. one tried to circle behind me , the other pulled his arm back to throw a punch, i blocked the punch and punched him in the solar plexus, he went down limmediately. the other guy ran up from behind , i was able to side step his punch and hit him in the solar plexux also. the whole thing lasted only about 50 seconds. but the thing that amazed me was, i knew i could seriously hurt these guys but didnt want to i was calm throughout the whole ordeal, but became very nervous after it was over... now i am in no way a accomplished martial artist, i am now a blue belt in kyokushin . and i am 42 years old . would any other person reacted diffrently, if so please respond.
