Back when I had a real job that I had to go to everyday they would get upset if I napped. Add to that the fact that coworkers would stare at you if you start drooling in your sleep things just weren't conductive to napping in the office.
The people who work at Google have no fear of naps. Apparently, the search giant encourages it. A picture has turned up of folks at the Googleplex HQ in California napping in a high-tech pod.
The fancy sleep pod is ergonomic, has a music player, and an alarm to wake the Googler before they oversleep. The pod is made by a company called Metronaps.
