The dataset card mentions 'TEMPORAL AXES' pointing to f_boxer_age and s_boxer_age columns, but these appear to be categorical text values (the card shows ranges like '20..orthodox' which suggests mixed/corrupted data). I need to inspect the actual values in these columns to understand what temporal data exists, if any. Let me check one of the larger tables to see what the age columns actually contain.",
