Scientists have developed a number of myths about themselves. They are, in one sense, the new priesthood, expected to bring us new technologies to make our lives simpler, easier and safer. They work away in these laboratories with complicated pieces of equipment lying around. They wear these spotlessly white coats that would show even the slightest stain, were they to be splashed with chemicals from one of their bubbling retorts. They are the new elite who deliver the goods to the front office where ageing managers sign off on advertizing campaigns to sell the latest gadgets and earn their commissions and bonuses. So we grow used to seeing the latest scientific journals full of the reports from these superbeings. They are couched in strange and incomprehensible jargon, accessible only by fellow scientists and other godlike beings. So it comes as something of a shock to see something written in a blunt, no-nonsense style. How can we take this as a serious piece of research when it is so easy to understand what it means?

Well, in this instance, there have been several years of work involved. The scientists started out with a complex hypothesis. They devised different methods for testing the various possible theories. Work began. Data were collected and numbers crunched. Slowly, a pattern emerged in the results. It was a revelation. Used by countless generations, the traditional idiom was proved by the scientific method. "Use it or lose it" was the right answer! Back to the beginning. One of the more obvious facts of life is that, as men age, they become more likely to suffer from erectile dysfunction. A number of different explanations have been offered for this starting with the simple truth that they grow tired and have less energy, to more complicated explanations about the build-up of plaque on the lining of arterial walls. Now we have this new piece of research. One of the features of ageing is that the opportunity for sexual activity can decline. Couples grow old and get out of the habit. One partner can die leaving the other alone and reluctant to re-enter the dating game. Whatever the reason, some men can go some years without sexual intercourse. It seems that the muscles lose their tone when not used, that the soft spongy tissue inside the penis breaks down and is no longer able to hold as much blood to form the erection. Combined with the tendency of the arterial walls to harden with age and so lose their ability to dilate, and you have a classic recipe for erectile dysfunction. That's before we get to all the psychological problems of performance anxiety likely to affect some men as they approach the possibility of restarting sexual activity.

The evidence from this new research is clear. Men who continue to have regular sex are significantly less likely to suffer erectile dysfunction. Their self-confidence is strong and their bodies still in training. For men who are ageing and with some history of inactivity, the best way forward is by using cialis. Taken as needed about thirty minutes before expected sexual activity, this can boost performance and restore confidence. If there is some embarrassment about the prospect of asking a doctor for a prescription, you can now buy cialis online without the need for a prescription. Your privacy is respected, your reputation safe.

When toothpastes are no longer capable of giving people that shiny and bright smile, teeth whitening is the only alternative left. Having the perfect white teeth have long been advertised by toothpaste and other tooth products. Due to the aggressive marketing that they use, it is no wonder why a lot of people are finding ways to whiten their teeth more. One of the options that they have is teeth whitening. The perfect candidates for teeth whitening are those that have teeth that are discolored because of age, due to possible smoking and many other factors. Once teeth whitening was found out to work effectively, more and more people are enticed to try them out for themselves. And due to this need, there are now a growing number of ways in which people can have their teeth whitened. Some of these are: 1. Teeth whitening systems. This is the process of teeth whitening that you can do yourself and at home. Teeth whitening systems usually consist of whitening gels that needs to be placed in your mouthpiece for specific number of times. In order to maintain its effectiveness, you have to make sure that you comply with the required amount and time that is dictated in the whitening system. If you want to have your own whitening system, you need to have a minimum of $500 set aside as a budget. You can also opt for those that cost less than $100 but they do not work as well as its expensive counterpart. Before you buy the whitening system, it is advised that you check out their labels first. Most of them are already approved by the American Dental Association so you need to look for their seal of approval. Another thing that you need to keep in mind is to follow instructions to the letter. Do not go beyond what is required. You can always consult a dentist if you have queries regarding the whitening system that you are using. 2. Teeth whitening done by professionals. This is by far the most effective means of teeth whitening. The procedure is assisted by a dentist so you can be assured that everything will be done properly. There are steps that are needed to be taken before the actual teeth whitening. You first have to be examined by a dentist so they will decide if you need teeth whitening or not. Then he or she will suggest what type of teeth whitening will work effectively for you. The dentist will then tell you what you can expect from the procedure. Every whitening session varies from case to case. There are those that tend to be more successful than the rest. This will all depend on the condition that the teeth and how effective the procedure will be. Before an individual is treated for teeth whitening, the dentist will first have to clean the teeth to prepare them for the cleaning process. Then cavities are filled in. The teeth whitening process will begin once your dentist has checked that your gums are as healthy as can be. The two types of teeth whitening is not an assurance that your teeth will remain permanently white. Take note that the process is only temporary. Teeth whitening needs to be done repeatedly so that you can maintain that shiny white for longer times.

The kind of bleaching laser or light is enclosed in parentheses. 1.BriteSmile (gas plasma light/light emitting diode) 2.LaserSmile (a Biolase laser) 3.LumaArch (halogen light) 4.Rembrandt Sapphire (plasma arc light) 5.Zoom! (metal halide light) Generally, laser treatment is done by applying a 35% Hydrogen Peroxide gel-based solution on the teeth of the patient. After applying the solution on the surface of the teeth, a light is held several inches away from the patients mouth to activate the peroxide component of the gel. There are manufacturers and dentists who advertise that this method works better than tray whitening method. There are no actual data completed to support their claims.
