that's very true. also, i know getting hit a lot will damage your face and can change your features.
when i was in martial arts, my dad would not let me compete. the women i trained with that would compete professionally alllllll changed....one sensei, her nose was broken, never the same. her cheeks looked as if they were always swollen. just no bueno. but if you think about it, the women that do join combat sports are usually more on the masculine side lol.
