That part about humans using only 1/10 of their brain is because that's the amount that's actually connected to what you're doing. Rest of the brain is wired for other things: there are parts for each sense, part of the body, memory (spread all over) and several others. Someone who got all 100% of their brain active wouldn't really do anything because their body would simply jerk around, every memory would pop up simultaneously and their senses would be flipping all over.
