I think that intuition means that we like to "live within our heads" making plans and building theories but if we do that too often we'll get out of ENTP mode since it's the outside contacts that eventually charge us. Maybe it has to do with finding a balance where we're dragged back into life after a period of creative hatching?
I once heard a theory that could explain that couch potatoness but don't really remember it. It had to do with changing your behaviour to something really different when under stress than what it is normally. Someone please help, if you know what I'm talking about.
But being bored is something I really don't understand. Never have been, not even when I was a child. There's always too much to do. Or is it because of my E/I that are almost equal?
