Have you ever pulled an all-nighter to study for a test or get a project done for work? How about doing it 11 days in a row? A man in Cornwall, England, actually went 11 consecutive days without a wink of sleep.

Tony Wright, a 42-year-old horticulturalist, claims he has beaten the record of 264 hours (exactly 11 days) set in 1964 by 17-year-old American Randy Gardner. Wright had some practice: he had already been through more than 100 sleep deprivation experiments, with the longest one lasting eight days. He also employed a unique diet that comprised only raw foods. Wright claims that his regimen of salad, avocados, bananas, pineapple, nuts, seeds, carrot juice and herbal tea helped his brain to stay awake. He also says that it allowed him to "switch" from one side of his brain to the other when one got tired. (Whales and dolphins are known to employ similar brain-switching techniques, which allow one part of their brain to rest while the other focuses on breathing and other basic functions.)

In order to chronicle his attempt, Wright confined himself to a live music venue called Studio Bar in Penzance, Cornwall, and allowed a Webcam to monitor him the entire time. He also kept a blog for the BBC, though he stopped blogging on the tenth day because he found it too difficult to concentrate enough to write coherently. The public visited Wright at the Studio Bar or kept track of him through his Webcam.

Though it's believed that Wright broke Randy Gardner's sleep deprivation record, the Guinness Book of World Records no longer acknowledges sleep deprivation attempts because they feel that they're too dangerous. Some have also claimed that Gardner's record was already broken by Toimi Soni of Finland, who went 276 hours without sleep, and that the record was in the Guinness Book until they removed the category entirely in1989 [Source: The Times].
