[00:00:00]What happens to your brain if you don't sleep for 11 days?

[00:00:03]Meet Randy Gardner.

[00:00:07]In 1963, this teenager tried to break a world record.

[00:00:11]By day three, he was moody and slurring his words.

[00:00:16]By day five, he was hallucinating.

[00:00:19]He literally thought a street sign was a human being.

[00:00:23]On day 11, he tried to do simple math.

[00:00:26]He stopped midway because he forgot what he was even doing.

[00:00:38]He recovered, but Guinness banned the record because it's too lethal.
