From Wikipedia, the free encyclopedia. Randy Gardner (born c. 1947) is the holder of the scientifically documented record for the longest period a human has intentionally gone without sleep not using stimulants of any kind. In 1964, Gardner, a 16-year-old high school student in San Diego, California, stayed awake for 264.4 hours (11 days 24 minutes). This period of sleeplessness broke the previous record of 260 hours and 17 minutes held by disk jockey Tom Rounds of Honolulu.

The average adult bladder capacity is about 300-500 cc. The average bladder begins to feel full at about 100-200 cc. After voiding fully, the average bladder should contain less than 50 cc of urine. Some individuals with chronic urinary retention will have over 1,500 cc of urine in their bladders.
