Hi, I am a postgraduate student whose major is applied psychological research. Now I am researching my final thesis project that the Marriage influence in Male Boxers' competitive performance but I have a big challenge. I have to compare male boxers' record before and after their marriage but I can't find where or which website I can find these information about their marriage date. If someone know that, please let me know. That is so important for me. Thanks!!!!!
