Randy Gardner holds the scientifically documented record for the longest period of time a human being has intentionally gone without sleep not using stimulants of any kind. In 1964—as a 17-year-old high school student in San Diego, California—Gardner stayed awake for 264 hours (eleven days), breaking the previous record of 260 hours held by Tom Rounds of Honolulu
That is crazy, I can't even stay up for 24 hours 😛
