Boxing around that time was just as brutal, people would box for like 30 rounds, and if you knocked someone down, they wouldn't make the other boxer go to the opposite corner. They would literally just wait like a stalking tiger over their opponent till they got up. It was bonkers. And no 3-knockdown rule.
As a person who's been on the internet since 1994, I can tell you, never judge anything on what the Internet has to say. Everything I've ever purchased on Amazon has had scathing reviews, and yet none of the things said were actually true. Yeah, I'm saying most of the people online are insane.
