who never liked getting punched in any of the boxing matches or even sparring I engaged in, I'll speculate that you are agreeing with my reasons I do not want either my son or daughter who competed in the ring to do so again. My older brother suffered and eventually died as a result of being a boxer who would take five punches to land one -- because with that one, he usually won. But that isn't good for the human brain. And while mst people recognize the sport is corrupt, they tend to associate it with the money involved in big fights. After 60+ years in the sport, I can say without risk of error that it is just as corrupt at every level.
The strange thing, of course, is that I find boxers to be the most interesting people I encounter. Most -- though certainly not all -- are actually gentle people outside of the ring. I remember a show (either Mike Douglas or Merv) from either the late 1960s or early '70s) where a psychiatrist was a guest. He was talking about how complex human beings are. At one point, he noted that while boxing was the most violent of sports, he found boxers to be the moat gentle of people outside the ring.The host questioned him on how that could be? He said most had suffered in their early life, in one way or another, and by bocing, were telling the world, "Don't touch me in an aggressive way."
