I made about $14,000 that year as a mystery shopper, not including reimbursementsâthat's pure earnings. It was amazing how quickly that money grew: Thanks to my mystery shopping, I was able to set up automatic withdrawals each month from my checking account to an emergency fund and an account for house savings.
Each person's sleep requirement is different. Some people find that they only need 5-6 hours of sleep, while others need 10-11 hours for optimal performance. The average adult functions best with 7-8 hours of sleep a night; however, it is important to consider how much sleep you need on an individual basis.
REM sleep occurs at intervals of one to two hours, and is variable in length. REM sleep is characterized by irregular breathing and heart rate, and involuntary muscle jerks. Most adults need around eight hours of sleep on a regular schedule to function well, although some require less, and others more. (It has been said that men need an hour less sleep than women.) Children, particularly teenagers, often need nine or ten hours for optimal functioning.
