I saw this in the agency bar/cafe place today.
I guess it's supposed to be an insult but this seems like a superpower to me. A lightning bolt is quick but it illuminates the whole sky. I know a few people with attention like this; they seem like they're barely awake, but then they suddenly understand everything.
It reminded me of this episode of RadioLab about falling - including why everything seems to go slow when you fall, or find yourself in a life-threatening situation. It's becase your brain suddenly keeps all the stimuli it normally dumps - for a fraction of a second you notice everything. Then, when you spool back and remember it seems to take forever.
