The first time I saw professional boxing on television I was 5 years old. I believed that the fighter's were putting their teeth back in before a fight started and that they were angry at being without clothing. I was almost 10 when I actually tried boxing first hand and realized that my teeth and mouthguard both fit in my mouth, still I refused to let the other man get me in my underpants
