The broader point that's often missed is that this is a naturally occurring and common phenotype that doesn't gel well with office-work culture and the modern regimented schooling system, forcing people to sit for unnaturally long times focusing on anxiety-inducing problem solving all day. It's not normal, and it's a recipe for burnout, and our only answer, is not to change the system, but to try and medicate it away, with sometimes devastating consequences.
