There's also the long-standing idea that people come up with great/interesting ideas while in the shower (so much that it's an internet meme), and that's attributed to the shower being one of the few places where you don't have media or electronics trying to capture your attention.
That phenomenon is very real in my personal case. Unfortunately the ideas go away by the time i get hold of pen and paper after the shower. Possible solutions to this are welcome.
