(via Twenty Two Words) I watched this video hoping that it would vindicate my position in a long-standing argument with my partner that alarms spaced at half-hour intervals is better than hitting the snooze button every nine minutes for an hour, but it sounds like they're both awful, according to science.  Still, I love learning about details of sleep cycles, and this video captures the main points (including some information I didn't already know) in a quick, easy two and a half minutes.

Also this is totally unrelated but the narrator's voice sounds a lot like Michael from Vsauce, and I'm just sleepy enough to begin to wonder if it isn't a conspiracy... I mean, Mike from Idea Channel looks enough like Michael that it could possibly be CGI, and CGPGrey doesn't sound anything like either of them but voice altering software has come a long way, and he never allows himself to be photographed...
