Memory foam has been about since it was developed in 1966, but it has only been generally available for about twenty years, although twenty years ago hardly anyone could afford it.

One of the early uses of memory foam was for mattresses for the bed-ridden. This is because memory foam mattresses help minimize pressure on the skin touching the bed, which reduces the likelihood of bed sores and gangrene.

In those early days such mattresses were prohibitively costly so just hospitals and the wealthy could afford them. However, the cost of memory foam mattresses has sharply over recent years and now they can even be purchased on Amazon and.

To begin with this extraordinary foam was invented by one of NASA's spin-off research companies, so it is a product of the space program. At the time, scientists were attempting to find a safer material for use in cushions and pillows for the aeronautical industry.

They came across this foam, but NASA allowed the right to make it, the patent, to slip into the public domain.

A Swedish firm took up the challenge and made orthopaedic mattresses with it because of its capability of moulding itself to a body's individual shape due to that body's heat and weight, thus supporting the body at more points than a traditional mattress. It is this additional support that reduces pressure on the skin and so reduces the likelihood of bed sores.

Another property of memory foam is its composition. Normal foam is manufactured up of lots of bubbles per cubic inch which are in effect sealed off pockets of air. You body heat warms this air up and so keeps you warm.

This can be a good or a bad thing according to the background temperature, but normal foam is always warm.

On the other hand, the cells or bubbles in memory foam are not sealed off entirely so air can course between them. That means that warm air can escape and be replaced by cool air.

This permits you much more control over the temperature of the mattress by controlling the temperature of the room.

There are two types of memory foam high density and low density. One reacts to heat and the other to pressure (or in this case, body weight). Most memory foam mattresses are made up of a mixture of these two kinds of foam so that the top layer reacts to the heat of your body and shapes itself around you, while lower layers react to your weight in the same way, depending on how heavy you are.

The lower layers will permit the passage of cool air and this will be transferred to the upper layer, keeping your body cool. One point to make on this issue is that because memory foam mattresses react to heat, if you live in a hot country, the foam will become quite flaccid because of the ambient heat. Therefore, if you live in a hot country, the mattress will need to be that much thicker to permit more air to circulate.

Are you shopping around for a new job? Or have you ever wondered how much a truck driver earns? If the adverts in the truckers' magazines are to be believed, it is easy to get a driving job paying $100,000 a year as an owner operator.

This may be true, but it is certain that you can make a good living by owning and operating your own truck. There are several good reasons for this. There is a worsening shortage of people who are willing to drive long distances and stay away from home for a night or more and yet more goods are being imported and so have to be distributed from ports to distribution warehouses.

Many owner operators enjoy the lifestyle of being their own boss and not having anyone breathing down their neck. Owner drivers often take their spouse or their dog on trips with them and a modern cab is more like a small caravan that a car.

There are three main types of driving job available in the truck driving industry:

The first is the owner driver or owner operator. This type of driver owns his or her own tractor - the cab part that pulls the trailer.This operator is usually contracted to a haulage company and is paid per mile and is at least partially accountable for fuel and repair bills. It is normally the highest paying trucking option.

The second is the company driver. A company operator does not own his or her own truck and will usually get a wage based on hours or miles. A company driver typically does not have the same level of control over his wages that an owner driver has.

The third sort is the independent trucker. The independent trucker is fundamentally a mini haulage company. He or she has to find the loads, deliver them, make sure he gets paid, repair the wagon and everything else that a boss has to do, but without the corporate support and regular loads that an owner operator has from his haulage company.

If you are interested in this kind of business, the first thing you will need is a Commercial Drivers License (CDL) in the USA or Heavy Goods Vehicle (HGV) License in the UK.

Most truck drivers attend a truck driving school where they will be given intensive training on how to drive a semi, as the tractor-cum-cab is known as. Training will be given on driving and the written part of the state test. After graduating from the driving school, you will be able to apply for your CDL or HGV.

Alternatively, you may be able to get in with a large haulage firm that runs its own in-house training school. This is better still as it may guarantee you a job with that company for a while and that will help you found a financial history should you want finance to buy your own truck later.

Once you are legal, you can rely on your training school to help you find a job, you could phone around, look on the Internet or go and get one of those truckers' magazines where they advertise jobs at $100,000 a year.

Nearly all people spend a third of their lives in bed. Everybody knows that. Eight hours at work, eight hours 'at play' and eight hours sleeping. We even say: 'I have to get my eight hours beauty sleep'. I understand that some can do with less and that children, especially teenagers, it seems, need more. So, it makes sense to spend those eight hours a day, or night, as comfortably as possible, does it not?

After all, you would not like to work at a desk that was too low or too high and you would not like to walk around in shoes that pinched. It is the same. You have to have the tools that allow you to do the job as easily as you can and the tool for sleeping is a bed and its bedding.

In fact, the bed and the bedding should be chosen somewhat carefully if you are going to get the best night's sleep possible, which means that no-one can purchase a bed for you and be sure of making the correct choices. There is more chance of getting it right with some materials than others and one of those materials is memory foam.

This is because memory foam moulds itself to the contours of a body by reacting to its heat and weight. It provides more support over a larger area than conventional materials, This is most important in the mattress and the pillow. Some people have to have or prefer a hard or a soft mattress, that is personal preference, but the pillow is more universal.

All our heads and necks are pretty much the same. However, once again memory foam pillows are that little bit more adaptable to each individual's characteristics. However, you would be wrong to suppose that all pillows are the same size like the customary cotton sack filled with feathers or whatever. Foam, conventional or memory, can be cut to any shape and some people find wedge shaped pillows more comfortable.

Then some people prefer little pads for pillows and others prefer four foot bolsters. There are even sectional pillows made up of up to a dozen sections that you can assemble into practically any shape.

Memory foam pillows return to their original shape when you get off them. It may take an hour but that is why they are known as memory foam pillows. This means that they do not require fluffing up each now and again. Being inorganic, they are hypoallergenic, impervious to mildew and dust mite resistant, which will help a lot of allergy sufferers.

Memory foam pillows are comfortable for sleeping on your back or side. They are not the cheapest pillows on the market, but the price is coming down all the time and they will last quite a few years if you get a good one. See if one of your local retailers can show you a sample or even allow you a thirty day satisfaction warranty then you have no risk.

Cream floats to the top, as the saying goes and that applies to many other things too. The best games have been around for thousands of years: chess, draughts, cards and ludo. The favourite hobbies have been the same for donkey's ears as well: flirting with the opposite sex, riding horses, breeding dogs, hiking, sailing, travelling and keeping up with the latest technology. However, until recently, keeping up with the latest technology was quite easy.

New models came out every few years before, but nowadays they come out every couple of months and most items you buy have been surpassed by the time they get into the shops. Computers, especially laptops, and mobile phones are prime examples.

And so is auto navigation or sat nav as it is often known as. Auto navigation systems are based on GPS or GPRS and this technology is at the cutting edge of electronics because the world's military relies on it and they have a great deal of spending power.

However, cream floats to the top and so it is with auto navigation systems too. The best auto navigation system manufacturers have been constantly good and at the cutting edge of the fairly old idea of GPS. In this article, we will run through a few of the leading makers of auto navigation systems

Tom Tom is world-famous for its quality. It is also well-known for repeatedly manufacturing some of the smallest auto navigation systems. Small does not necessarily mean better, but the quality of Tom Tom auto navigation systems is beyond doubt.

However, if you are not having your auto navigation system fitted by your car's manufacturer, space may be at a premium and so a Tom Tom sat nav system may be ideal for you. If you have a bluetooth-enabled cell phone, you can link them together without wires, wirelessly, and make use of their up-to-the-minute weather and traffic data while you are en route.

Garmin auto navigation systems are time after time one of the most feature-packed and up-to-date auto navigation systems on the market. Despite it being just about the most feature-rich sat nav system on the market, it is not always the most expensive. However, learning to use all of the Garmin's functions can take a long time, but it is normally the auto navigation system that the tech nerd would like to get his hands on. It is bluetooth enabled as well.

Magellan is well known for its portable auto navigation systems. They make a variety of types of devices, but they are most well known for their portable auto navigation systems. So, you can use your Magellan sat nav system in your car, then take it on your boat or on hiking or bicycle trips.

There are auto navigation systems to match every pocket and every situation, so if you travel a lot, these manufacturers' names should be on your short list. Auto navigation systems are perfect for individuals who travel, but they are also great for locating different routes through town to avoid hot spots. You do not have to make use of them every day, but they are good to have, if you do need them

A lot of people are very concerned about privacy and security issues regarding GPS auto navigation systems. This does not only involve your in-car sat nav, but also portable devices such as your cell phone.

These days most people can be traced one way or another, whether it be by their mobile phone, their GPS auto navigation system or an RFID tag that was sewn into a shirt they bought last month at a supermarket.

Some people do not care about this state of affairs, some deplore it, but most people are not even conscious of it. It is hard to avoid being tracked. It is often stated that anyone walking around London carrying out his or her routine daily life these days, shows up on a closed circuit TV screen about 300 times every day.

However, there are benefits. If I was being attacked in London, I would hope that someone could see me on a screen and call the police or if I was mountain climbing and I fell and broke my leg, I would be pleased that the rescue personnel could track me because I was using a GPS enabled cell phone.

Luckily, there are fairly strict laws in place in most Western countries limiting what can be done with the intelligence gathered from GPS auto navigation systems. The issue is that everyone knows that governments break the law and can change them to suit themselves whenever they like. No-one trusts politicians. Not even politicians.

This creates a huge dilemma for a lot of people and especially parents of young children. Do you switch on the tracking options of a GPS enabled mobile phone so that you or your child can be found if lost or injured or are you scared that that information could be misused by a criminal of some kind - a kidnapper or a paedophile?

None of us actually knows what our governments are up to or capable of, but we are being wound up by films and books about the widespread invasion of our privacy and what clever people can do with the information that is floating around us in the air.

In reality, we have all given up a lot of the privacy that our grandparents took for granted, but the apparent risks to society are greater these days, although 9/11 could have happened to the Empire State Building 80 years ago and anthrax could have been released on London or New York 100 years ago. People do not have to have high technology to bring out atrocities. Look at World War One or Rwanda.

GPS and auto navigation systems are good things. They help you stay aware of where your dear ones are and give you the peace of mind that if they get into trouble they will have a better chance of getting out of it.

The information gathered by these GPS auto navigation systems can be used in the wrong way, that is indisputable, but at the moment it probably is not. However, using GPS auto navigation systems can help keep you and your family secure.

Maps are fundamentally defective. By the time the surveyors have finished and the data that they have collected has been mapped out and the printers have published the map and sent it to the distributors and they have sold it to the shops and you have made up your mind to buy one, it is out of date. Sometimes years out of date

Another difficulty is that it is impossible to read a map and drive carefully at the same time. You cannot study a map and look out of the windscreen at the same time. So, you either have to have a passenger who can read a map, or you have to stop repeatedly and memorize a small part of the map. That is all right, people did it that way for a hundred years or more, but now there is a better way.

GPS satellite navigation systems have been around for a long time. At first they were only utilized by aircraft and ocean liners. As the price fell, yachting people could afford them; later still long distance lorries had them, then very expensive cars and now virtually all cars.

In spite of the odd story of someone driving into a river in the dark, because the driver trusted the sat nav and the sat nav did not know that the bridge had been removed, the auto navigation system has been a resounding success.

I am certain that family Sunday outings are far more pleasurable now that the spouse does not have to do the map-reading; lone travellers do not have to stop to get their bearings and lone female drivers are safer because they do not have to stop to ask directions.

Being lost at night or having broken down in the countryside or even taking a wrong turn into a rough district of town is terrifying. Even if you have your cell phone to call the breakdown service, you have to know where you are and if you are in a rough area of town by mistake, you do not want to stop to ask the way and you certainly do not want to go farther off the beaten track.

Then there are the detours that we want or have to make because of natural disasters, break-downs, traffic jams and roadworks teams. Often you will get advanced warning on the local radio of trouble spots up ahead, but if you do not know the neighbourhood, there is not much you can do about it. Unless you have an auto navigation system.

I know many people who do not use their auto navigation system every time they get into their car and that is how it should be for those people, but it is like insurance, it is nice to have it when you require it.

No-one needs an auto navigation system to go to the neighbourhood shop, but it is really nice to take the scenic route the next time you go out of town to visit a relative. Perhaps you always take the same route when you visit your Aunty Lil, but with an auto navigation system you can vary your journey to pass local attractions.

No, it is certainly not true that you could rise to fame and fortune if you go and buy a hybrid car. But a hybrid car is not only a vehicle for the wealthy and famous. But it might be right for you. Many famous people are driving hybrid cars nowadays including some of the most well-known in the world like your favourite movie stars. But the big question is, ought you to be driving a hybrid car at all?

So, are you driving anything like a hybrid car? Well, if you are not, you won't get pally with some of these hybrid car-drivers. These people were very early drivers of hybrids cars. You may not see them in a hybrid vehicle when they pull up next to you on Rodeo Drive, but believe me, they've owned a hybrid car before. Whatever, believe me or not they have been reported as driving hybrid cars in the past.

Alicia Silverstone This star definitely isn't clueless about the environment. She knows that driving hybrid cars has many benefits. And if the general public doesn't have the understanding that she has, then that's just hard luck. Alicia knows that hybrid cars are good for the environment and therefore for everyone. So Alicia Silverstone got herself a hybrid car. So she has helped promote this new technology as far as this article goes.

Ellen DeGeneres Now then, this funny lady not only has a great haircut, but she was driving a great hybrid car even before you probably even knew about hybrid cars and she was probably smiling at you and your gas-guzzler last time she wizzed past you.

Robin Williams Funny and sweet, Robin knew when he played the role of Mrs. Doubtfire that he should probably start thinking more like the sensible driver that you would allow to transport your kids to and from school, so Robin got himself a hybrid car, and he hasn't looked back since.

Ted Danson Cheers! Ted knows a great car when he sees one. He was certainly sober the morning when he decided to go check out the new cars on the lot. He got up and bought a car that made a great deal of sense. He was making good sense when he chose a hybrid car.

Brad Pitt What's up? Certainly, not Brad's petrol bills 'cos he's got a hybrid engine! He's had a hybrid car, so he knows his car isn't using that much petrol.

Prince Charles Why, surely, if it's good enough for royalty, then it's good enough for the rest of us? That's how you should feel when you own a hybrid car. You should feel proud, adorned, and admired because believe it or not, that's just what you are when you choose to drive a hybrid vehicle. So enjoy it.

So, how do you feel? Like a million dollars? Well, you ought to if you are thinking of buying a hybrid car and don't worry, you won't have your 15 minutes of fame, but you will be making a very bold statement that people will understand and many people will applaud what you are doing and that will go on for years and years because hybrid cars last for decade or more.

It appears that every new car you see these days has an auto navigation system. They are impressive as well, there is no doubt about that, but how many drivers utilize them to their full extent?

The first navigation systems to become reasonably priced did not have maps and did not have voice instructions, but then they were for use by yachts men and women. They were also fitted in commercial vehicles fairly early on, but when they were first fitted into cars, it was only into the Bentleys and Ferraris of this world.

Now auto navigation systems are cheap enough to go in a Ford. And that is great, but they are still often part of an upgrade package, which most people do not really require, because they are too atechnical to get the best out of the sat nav.

If you travel long distances to different places on a normal basis, then an auto navigation system is very handy, but your employer has almost certainly already installed them in the fleet cars for the sales force. Likewise, an auto navigation system is very handy if you are lost, but how often do people go to places where they run the risk of getting lost?

It seems to me, that the best use of an auto navigation system to most people is to steer clear of traffic jams. However, this means sitting down with the instruction book and learning how to use the device correctly.

An auto navigation system can easily help you steer clear of such obstacles as road blocks, traffic jams and accidents. If you ask it. It can also help you find ways to where you want to go that you would never have thought of even if you do know the neighbourhood quite well. If you know how to ask it.

It is a real shame that people buy this technology, or any other for that matter, in order to make an impression on their friends and never realize the full potential of what they have within their reach. OK, if you have more money than sense, you may think why not?

But the population of the world is beginning to think about excess and how we can save resources, so really you, the world and everybody in it would be better off, if you did not fritter away your money, or worse still, get into debt just to show off. This is a warning sign of where we went wrong last time.

An auto navigation system can be a real boon because it can help you save fuel by choosing direct routes and also help unclog our roads by showing cars alternative routes. If you have an auto navigation system, learn how to use it and you will see the great benefits that are locked away inside that little box; but if you are buying a new car and you know that you will never be troubled to learn how to operate it, do everyone a favour and just do not have an auto navigation system fitted.

Auto navigation systems or sat nav systems, as they are frequently referred to, are in nearly every new car or truck that is purchased these days. But what about older cars and trucks?

Older cars and trucks can also take advantage of these new auto navigation systems because of the different installation options open to drivers. An auto navigation system does not have to be installed by the manufacturer of your automobile.

In fact, there are many third party installers of auto navigation systems: there are 'specialist technicians, garages will do it or you can do it yourself. True, you may run into difficulties if you want to cut a hole in the instrument panel of your car or truck and you may be unwilling to remove your CD player in order to install one, but there are also loads of models that can be attached by other quite simple techniques.

Furthermore, if you do not only travel by car, there are other options that you may prefer, such as the portable options so that you can take your sat nav in your boat on the water with you or on a bicycling or hiking vacation.

These portable devices range in quality, but they still work well and are becoming better all the time. Satellite navigation by laptop or PDA is another option that offers good quality mobile information.

The major problem with conventional paper road maps is that they are out of date before you get them. Some of them are years and years out of date as they may have lain on a bookshop shelf for a very long time.

In contrast, GPS or GPRS satellite navigation systems normally provide information that is up to the minute on important information like traffic jams or floods and up to the hour on lesser problems.

This up to date intelligence is being typed into the database twenty-four-seven by thousands of intelligence providers world-wide and then sold on to the people that manufactured your sat nav system.

You automatically buy a license to access that data when you buy your sat nav system. However, you may have to renew your license every year.

When it comes to choosing one of the auto navigation systems, remember to check the service and licensing particulars. Another point to bear in mind is the cost of the auto navigation system and its installation cost. Having sat nav fitted by the producer of your vehicle is the easiest alternative, but it is by far the most expensive one too.

You perhaps pay between double and treble for this method of installation, but if you are buying your vehicle on finance, well, you will be paying interest on that for five to ten years as well and that will mean that you will pay closer to ten times what it would cost to have sat nav installed by a third party.

It is unquestionably worth bearing in mind when you go to purchase a new car and see one of those fantastic auto navigation systems pre-fitted.
