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.
In general, most healthy adults are built for 16 hours of wakefulness and need an average of eight hours of sleep a night. However, some individuals are able to function without sleepiness or drowsiness after as little as six hours of sleep. Others can't perform at their peak unless they've slept ten hours. And, contrary to common myth, the need for sleep doesn't decline with age but the ability to sleep for six to eight hours at one time may be reduced.
