The invention of the laptop computer opened up a myriad of possibilities for the itinerant businessman. Gone are the days when you had to carry a bulky attache case stuffed with unwieldy documents like a Thanksgiving turkey. Imagine the embarrassment of the pre-laptop days when you had to sort out stacks of printed papers in front of an impatient client. Good thing a highly imaginative guy named Alan Kay made possible the invention of the first laptop prototype in 1968. Dubbed as the Dynabook
, the idea was to provide people with a “personal portable information manipulator.” However, it wasn’t until September 1975 that the first commercially-available portable computer was introduced to the public. Compared to recent day laptop computer models, the first portable is crude. Primitive
, it may be; but it does the job better than that monolith of a desktop computer that people used to work on in the office.
The invention of the laptop freed the modern businessman from the fetters of disorganization and the clutches of the bulky desktop. Vital business information can now be carried anywhere the businessman might go. This is crucial since the ever-increasing demand of the growing market requires entrepreneurs to be more flexible in dealing with the needs of their clients.
The dawn of the Internet age added more power to the compact computer. Once limited as a portable device to carry information and necessary documents is now upgraded into a dynamic tool for communication and whatnot.
Due to its larger storage capacity and faster processing speed, the modern laptop computer can deliver a performance that can equal the efficiency of an entire business office in the 80s. It can store a large amount of information that would fill up a whole building during the pre-laptop days, it can research about the latest trends in the stock market
, it can facilitate consultation with a client from India, and it can do almost anything that a modern businessman needs.
The usual size of a notebook computer ranges from 10?8 inches to 15?11 inches. It can weigh from 3 to 12 pounds. The ever-downsizing incarnation of the modern laptop computer makes it more favorable for the travelling businessman. Albeit its tendency to get smaller and smaller with every new model, one thing is for sure-its capacity to perform monolithic tasks won’t dwindle.

We all sleep
, and almost certainly not as much or as soundly as we would want. Just how important is sleep? Are there hazards connected with not sleeping as long as we would prefer? New research implies that sleep is substantially more important than you might have believed.

Animal research suggest that sleeping is as critical as food for survival. Rats, for example, typically live about two or three years
, but they live only about 5 weeks when they are deprived of?REM sleep and merely 2 or 3 weeks if they’re deprived of all of the sleep stages-a time period similar to death resulting from starvation. But how much sleep do people really need? To help answer that issue, scientists look at how much people sleep when time and agenda are not at issue, the average degree of sleep amongst different age groups
, and how much sleeping tests show is required to be most effective.

Any time healthy adults receive unrestricted opportunity to sleep, they sleep on average between 8 and 8.5 hours a night. However sleep needs vary from one person to another. Some people apparently require only about 7 hours in order to avoid problem sleepiness whereas some others will need 9 if not more hours of sleep. Sleeping preferences also shift through the entire life cycle. Newborns rest between 16 and 18 hours a day, and youngsters in preschool sleep somewhere between 10 and 12 hours each day. And how important is sleep to kids? Well
, school age children and teenagers need to have at least 9 hours rest each night.

The bodily hormone influences of puberty tend to alter youngster’s Circadian_rhythm. Consequently, teens will probably turn in later than younger children and adults, plus they tend to want to sleep later each morning. This sleep-wake habit is opposed to earlier morning start times of a lot of high schools and helps make clear the reasons why most teenagers get an average of just seven to seven and a half hours of sleep each night. It also helps explain why teens can be so very difficult!

As people get older
, the pattern of sleep also changes-especially the amount of time spent in the deep sleeping stages. Children seem to require much more of their sleeping time be spend in deep sleep than do adults. This explains why children can sleep through loud noises and why they might not wake up when they are moved from the car to their beds. Once the adolescent years begin, a large part of this deep sleep is replaced by much lighter stage 2 sleep. Between young adulthood and midlife, the percentage of deep sleep falls again- from less than 20 percent to less than 5 percent
, one study suggests-and is replaced with lighter sleep (stages 1 and 2). From midlife through late life, most people’s sleeping pattern has more interruptions by wakefulness during the night. As these sleep interruptions increase with age we are faced with losing ev.
