you can read about fights lasting silly numbers like over a hundered do you really believe fighters trained then as they do now they used to drink through training they were not educated in how to take care of their bodies and what effect bad living would have.

an old rule in boxing is that a round would end once a fighter had been dropped so obviously a fighter would drop down to end the round if tired thats why fights lasted so long i think this came well before JJ time but still it shows how badly the sport was run
