I guess we've known for years that the amazing human brain can solve the most complex of problems when you think you're not thinking about it. The answers emerge in the shower and other unlikely places.
Fantastic example of that in the middle of last night. I have some corrections to do to my doctoral thesis next week, then I can graduate in June and I know what I've been asked to do, but have studiously NOT been thinking about how I'll do it until next week. Last night - the whole answer just unfolded when I was asleep. Obviously my efforts to not think about it consciously didn't fool my sub-conscious. Hope I can remember the answer when it comes to writing it down!
How lucky we are. We should give our brain more problems, then try not to think about them!
