If you have ADHD, emergencies are common because the dopamine to motivate doing stuff isnt there so the extra norepinephrine from procrastination’s consequences finally brings your norepinephrine levels “high enough” to be “normal” (its usually below normal for us) while an average person is going to be swimming in it enough to be paralysed. So the same reason that we tend to procrastinate is also why we tend to be chill when everyone else is freaking out. Not only are we used to those scenarios, our brains are ironically, the only ones that are going to be “normal” during those emergencies.
