“Danger, when it is always imminent, does harm. It doesn’t need to actually arrive. You exhaust yourself in the act of forever looking over your shoulder. Your body readies itself to fight and never quite discharges that chemical cocktail. You channel it instead into anger and self-pity and anxiety and hopelessness. You divert it into work. But really what you do, with every fibre of your being, is watch. You are incessantly, exhaustingly alert. You don’t dare ever let up, just in case the danger takes advantage of your inattention. I’ve forgotten what it feels like to have space in my brain for anything other than watching.”
