"If there is one general rule about the limitations of the human mind, it is that we are terrible at multitasking. The old phrase “united we stand, divided we fall” applies equally well to the mechanisms of attention as it does to a patriotic cause. When devoted to a single task, the brain excels; when several goals splinter its focus, errors become unavoidable.

They were attending the championships of one of the world’s hottest computer games, StarCraft 2."
