All:
On reflection, I realize that my responses here were the result of my current position - as a man who is getting older. A silverback if you will.
We are not as likely to be pulled into the monkey dance. I would not be at a party where such things happen, I would not be a similarly-situated target of opportunity for a loudmouth punk.
However, we also are aware of our mortality. We are often somewhat more fragile in places, we don't heal as fast, we're not as fast as we were. We cannot afford to be drawn into a fist-fight, and we can't let ourselves be picked to death by crows.
So that has an impact on my response. I cannot and will not allow myself to be the target of slowly-building rage and aggression. At the first sign of it, I have to leave immediately if I can, or utterly destroy whatever threatens me if I cannot. There can't be a test of manhood or a mutual show of force. There cannot be a case where I just take my whippin' and get on with my life - it might kill me literally to take a beating from a young guy who knows his business. I have little stamina, but I do have strength. I have to judge when to use it, but if I use it, it's all in, all or nothing. Nothing held back, young punk is going to get it all; that's all I have.
That would not be the appropriate response, I guess, for a younger guy. For me, I think it's about the only alternative I have. Watch a silverback gorilla fight a young challenger some time. It's freaking brutal. If the young upstart doesn't get the upper hand, the silverback runs him off entirely or kills him. Neither get a second chance.
With an older guy versus a younger guy, it's not about dominance; it is about survival. I want to live. If Joe-Joe the Rat Faced Boy doesn't realize he started a fight that ends with him on a stretcher, or me dead, that's his fault.
This is an important distinction. I think exactly this way when I'm injured. I remember having a significant back problem for a couple of weeks when I was in my early 30's. My now-wife was with me, and asked if I'd still be able to defend myself if something happened (we talk about stuff like that a lot). My response was that they'd get exactly one chance to finish me or leave, because the instant I knew something was on, I'd have to use everything I had on them. I would only get one chance before the pain would likely take me down, so I'd be violent and unforgiving. My only other option was to let them win.
I think that's Bill's point.
