#7 Any time less than five minutes to fall asleep at night means that you are sleep deprived. The ideal amount of time it should take to fall asleep is 10-15 minutes.
#8 17 hours of sustained wakefulness will lead to a decrease in performance that is equivalent to having a blood alcohol level of 0.05%

#17 Driving drunk and driving while tired are equally dangerous.
#18 You may feel or claim that you are used to less sleep than you need, but in reality your body is never truly able to get used to it.
