”Dave Grossman, a former army lieutenant colonel and the author of On Killing, argues that the optimal state of ‘arousal’ – the range in which stress improves performance – is when our heart rate is between 115 and 145 beats per minute… ‘After 145,’ Grossman says, ‘bad things begin to happen. Complex motor skills start to break down. Doing something with one hand and not the other becomes very difficult. … At 175bpm, we begin to see an absolute breakdown in cognitive processing. … The forebrain shuts down, and the mid-brain – the part of your brain that is the same as your dog’s … – reaches up and hijacks the forebrain. Have you ever tried to argue with an angry or frightened human being? You can’t do it."
