As a longtime night owl - perhaps stubbornly so - I find this headline rather vindicating: Bright ideas come to us at night, not in office hours.
The article claims that, "research now suggests that if you want to be the wisest, you really need to stay up - well, until 10.04pm at least. This is supposedly the best time for a eureka moment, according to research."
Good stuff. Now, if only the article's author would actually cite what research study says this I will sleep better at night.
