everybody knows that sleep is the most essential part of our life , moreover without sleeping a person can last no more than 10 days( beside without food a person can live longer- more than 2 weeks)

*The record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.

*Most of what we know about sleep we’ve learned in the past 25 years.

*If you lose two hours of sleep, you can impair your performance equal to a .05 blood-alcohol level

*Some studies suggest women need up to an hour's extra sleep a night compared to men, and not getting it may be one reason women are much more susceptible to depression than men.

*Dolphins have to be conscious to breath. This means that they cannot go into a full deep sleep, because then they would suffocate. Dolphins have "solved" that by letting one half of their brain sleep at a time.

*Every 50th teen is doing pee-pee while sleeping

*The most common pose for sleep is so called "embryo pose"(41 %)

*Every 4th married couple sleeps separately
