It's funny, my input buffer may be small and it's a large mental drain to read busy code (ADHD con), however once I grasp how a code base works it's just there (ADHD pro).
It makes me wonder if it's related to the hunter-gatherer origin hypothesis. In that scenario covering large tracks of land was beneficial and that ability can be used to mentally map code. The flop side this also leads to distractibility and boredom paying attention to monotonous details.
