Hollywood Photographer Says He Went 40 Days Without Sleep

If you thought the DaVinci Sleep Schedule was intense, check out what this Hollywood celebrity photographer is doing: Tyler Shields says that last month he completed 40 days straight without sleep. This story may belong in the nearby Ripley's Believe It Or Not! Odditorium , but if true, experts think it's a very dangerous endeavor.

Shields, however, found it "an interesting way to create different brain waves and see things differently," he told KTLA. "As the years have gone on and I have to do more work and I have to do more things it's just become less and less need for sleep."
