Thank all of you for the suggestions. I agree that getting on the recovery path is the best thing for him. He was afraid what people would say about him if he got into a fist fight at his age and how it might escalate into a bigger feud, but my advice is to do the good work and if he as to defend himself then try do so but then try once again to reach out to the other person to let it finally go. The other person is still drinking so thats why they won't just move on.
