SFWeekly: In the Sack at the Exploratorium
Apparently we spend more than 27 years of our existence doing absolutely nothing. During this time we could be researching a cure for cancer, helping attain world peace, making billions developing the next big thing, having crazy sex, or holding down a beach somewhere, drink in hand. Instead, we're sleeping. It seems like a total waste of time, right? Well, hold on there, overachievers. “After Dark: While You Were Sleeping” at the Exploratorium sheds light on what goes on in the dark and why it's important.
