Would be worth further study. I don't know how to describe it either but it changes your way of thinking - at least subtly. Makes you stretch your brain and bifurcate your focus from one thing at once to two (or more). You never wind up being able to fully concentrate on two things at once but with practice you start to get good at it - you become able to do two things decently well at the same time, constantly shifting back and forth between them almost automatically.

Not sure in what ways this stretches the mind but it certainly does feel a bit different for the first while.

What are you all doing 5x though? Except a few actions, I generally did things once and it happened 5x. Except opening up npc quests, logging on, etc.
