Not enough sleep or disruptions to the sleep-wake cycle (such as those that may occur with shift work or travelling to a different time zone) cause the physiological state known as fatigue. Staying awake for 24 hours leads to a reduced hand-to-eye coordination that is similar to having a blood alcohol content of 0.1.
There are 13 hearts in a standard 52 card deck. There are also 13 diamonds, 13 spades and 13 clubs.
THE DECK HAS 4 QUEENS, AND 13 HEARTS. BUT IF YOU DRAW THE QUEEN OF HEARTS----- REMEMBER THAT THERE ARE ONLY 12 HEARTS THEN LEFT IN THE DECK. GOOD LUCK. Linda B Â· 8 years ago.
