Earlier quoted context omitted.
I don't know how else to tell you that anger very, very, very literally gives a person energy. Amongst other emotions (like fear as I have already mentioned, but also e.g. excitement), part of its arousal is your body being flooded with epinephrine et al, which provokes a significant boost in cardiovascular performance. > The original claim was "do what needs to be done" and now you backtracked to claim that instead…
(a) recall that I made a utility judgement, not a value judgement: "anger = useless" (b) That an adrenaline dump provokes a significant boost in cardiovascular performance is true. We are neither fighting anachronistic saber-toothed tigers, nor are we in the wild west, we are in civilised countries in the 21st century. When should improved cardiovascular performance improve any outcomes?
And, again, if you don't have the emotional regulation to not fly off the handle at things that aren't actually dangerous or threatening, that's a you problem not a problem with the existence of your limbic system.
