My latest TED Talk, about my adventures with four in the morning, is here if you're interested. It's a follow-up to my 2007 TED Talk about . . . my adventures with four in the morning.

Talk trivia: the watch I'm wearing was a TED speaker gift in 2007. The batteries are long dead but I thought it would be appropriate to set the hands to 4 a.m. and sport a little theme-bling.
