I have had a love afair with 4am (0400) since I was a child. I may even have blogged this video before but it just came up as the first TED Talk in a playlist "Playlist (10 talks): Talks for binge-watching" linked in the latest TED Talks email.

Rives: The Museum of Four in the Morning | TED Talk | TED.com

Rives' first talk about 4 am, "The 4 am mystery."

This is a link to the poem he mentions near the start.

I can identify with Matt Groening as well, mentioned in Rives' talk (the first linked here) as, like me, "not a morning person" and seemingly as nocturnal as I am.
