Feeling Sleepy

1 June 2010 - In 1964 17 years old Randy Garner from San Diego did not sleep for 11 consecutive days and set the world record. The student suffered from memory loss, had hallucinations and behaved erratic, but stayed awake all the time. He was kept awake by Stanford University scientists around him, otherwise he would have fallen asleep within 48 hours, according to one of the scientists. People who stay awake for long periods will develop a pattern of micro power-naps (sometimes they fall asleep for only a few seconds). It is not yet exactly known how long human beings can stay awake. Rats can survive for two weeks only - they can survive longer without food, and rats are probably stronger than human beings. When Randy finally fell asleep, he slept non-stop for 14 hours.
