Not only primates, I am surprised by the irrational primate attitudes of many humans..I don't talk about punch..Many people today have not learned to listen. I meant spar with words hand to hand, Fighting using logic, conversation, discussion and intelligence. I'm 66 years old with many mistakes and errors in my life, possibly more than those in this forum and I've never used my fists, but I've always used my head to defend my ideas and my rights in life, at work and in the family.
