I find it odd that the title says "Science Explains...", but then the main reference is to another blog post[1], which itself does a much better job at quoting and referencing scientific information...
Interesting post, but I don't recall ever getting great ideas in the shower myself. Anyone else care to share their shower stories?
In the morning right after getting out of bed? Those ideas were/are nothing compared to the ideas that came to mind while running 5 miles in the woods in college and then in the shower afterwards. Runners highs are awesome!
