According to the National Sleep Research Project:

–The record for going without sleep is almost 19 hours.

– People can take a cat nap, with their eyes open, and without being aware of  it.

– Scientists can’t explain the 1998 study that showed that a bright light shown on the back of human knees can re-set the body’s sleep-wake clock.

– The 1989 Exxon oil spill, the Chernobyl nuclear accident, and the Challenger space shuttle disaster were all linked to human errors caused by sleep deprivation.

– Teens need as much sleep as small children.
