"Dirty fighting," "sucker punches'" and "poaching" are short sighted ploys that are counter productive in the end. Eventually we will all die and all we will leave behind our legacy. I try to act so that mine will exemplify honesty, trustworthiness, and dependability rather than snarky, behind the back ploys
You are only fighting, needing to punch, or dispatching animals for survival, if things are pretty bad. Geezers are by definition at a competitive disadvantage and to survive need to consider going beyond what might be considered "fair" - even being "snarky" [whatever that means] and using "behind the back ploys."
We are discussing situations in which the goal is survival, not building your resume in the community. In such times, to be blunt, if the situation forces the choice, it is okay with me for you to go to your legacy first.
