"woz you lookin at my girlfriend?"
Funny, I always thought that the only reason that our particular species of human was able to rise to the pecking order as it did or currently “dominate” other species was in the fact that we had evolved enough mental capacity to understand that a stick could be used as a viable weapon, fire making or hunter gatherer tool and not just for scratching your own arse or amusingly flinging your flaming faecal matter at the cave wall.
I am sure that before this (and still during) we probably did go around punching or slapping the shit out of each other.
Anyone - no matter their perceived level of civilisation will resort to violence if pushed far enough or if the need arises to protect or dominate and this has always been a natural state.
Even individuals or children not exposed to violence (“innocents”) will naturally clench their fists in anger - although also a sign of manipulation.
Clearly we have physiologically evolved our hands from knuckle dragging (in most places!) to tool wielding, but just like every dog is a wolf, every human is a potentially violent psychopathic ape waiting to knock ten shades of shit out of each other if pushed enough or the obligatory 10 pints, curry n fight Friday night debacle.
And yes I too have suffered from “boxers/brawlers” injury and yes I too have been trained in various martial arts.
Now, if only our fists were as hard as Chuck Norris’s chin….
