My son has this habit of getting insanely deep into something when he is interested. Now, it is a Rubick's cube. Almost 24/7 he has that thing in his hand, solving it. He goes to bed with it. My brain fries when trying to figure it out. He shows me how to do it, and I get it, but man it's definitely a different part of the brain than I'm used to using.
