why do veins show on my face

Telangiectasia, the medical term for spider veins and broken capillaries, may appear anywhere on the face, typically around nose or under the eyes. The causes of spider veins on the face may differ from the causes on the legs or other areas. The red or bluish threads are injured veins or capillaries. Spider veins are usually harmless, but some people have a cosmetic concern over the condition. In fact, the American Academy of Cosmetic Surgery found that 50 to 55 percent of American women complain about spider veins. (See Reference 1) Spider veins develop from a venous deficiency. The deficiency comes from a back-flow of blood in the veins; the pressure causes damage to the vessel walls. Prolonged inflammation, high blood pressure and obesity are some of the medical causes for venous

why do we waste so much food

With the world's population growing, there's more and more waste being produced each year. All this week Nel's been looking into the inventive solutions people have been coming up with to put what we throw away to good use. Experts think that as much as half of all the food produced in the world ends up going to waste. It's estimated between 30 and 50% of all the food produced in the world never even reaches a human stomach. A report by the UK's Institution of Mechanical Engineers blamed food having strict use-by dates and consumers expecting fruit and vegetables to look a certain way. With the world's population expected to keep growing some people are worried that there could be less food to go around. Nel's been looking at why so much food is thrown away and what we can do to reduce

 why do tomato plants turn brown at the bottom

why do tomato plants turn brown at the bottom

Q. I have two tomato plants in my garden. They grew up and out very quickly and appeared to be thriving during the beginning of the summer. The past couple weeks they have been looking worse and worse. There are lots of fruits on the plants but they take forever to ripen. I have noticed that the leaves are brittle and brown starting on the bottom, near the soil and has been working its way up. I thought maybe I was over-watering but I have since slowed my watering and they are still not looking the way I would like. I also have zucchini, pepper, onions, and cucumbers. My zucchini and cucumbers have been doing wonderfully all season but the past few days the zucchini is starting to look a little dead on the bottom as well. My peppers still are not growing. They were looking real bad for a

 why do we use matched cells in a colorimeter

why do we use matched cells in a colorimeter

What does matching mean? Matching of cells refers to the degree to which absorbtion cells will give a similar absorbance or transmission reading when empty or filled with water. The practice started at a time when spectrophotometer cells were not made very well and most absorbtion instruments were single beam (no ability to automatically adjust for the blank). As high quality cells from major manufacturers like Starna have become the norm and instruments have improved, the concept of matching has become less important. A poor cell can appear matched because measuring a cell with no sample does not test the accuracy of the path length nor the dimensional quality of the windows. The important elements of cell quality are listed below with the specifications that you can expect from Starna

 why do your muscles twitch after working out

why do your muscles twitch after working out

Experiencing twitching muscles after an exercise session is not uncommon, particularly if your muscles are fatigued or you are not getting enough electrolytes in your body. Taking measures to alter your workout routine and watch your diet can help avoid twitching in many cases. If your twitches persist, however, consult a doctor to rule out an underlying medical disorder. Muscle twitches, medically referred to as fasciculations, are contractions of small muscle groups that are not particularly strong and are localized to one area. According to Sports Medicine physician John Su, post-exercise twitches are very common in the calf, hamstrings and quadriceps, and are essentially low-grade cramps. Unlike cramps, however, muscle twitches are not painful and usually only last for a few seconds,

why do we celebrate halloween in canada

Origin and History of Halloween in Canada From the historical records it is known that Halloween developed from the ancient pagan festival observed by Celtic (present UK, Ireland and northwestern France) people over 2000 years ago.

 why women should be allowed in combat

why women should be allowed in combat

No, men can do it better. No, women should not be allowed to fight in combat, because there is no reason to think that women can do the job better. It is a fact that men are stronger than women. There is no need to tolerate higher casualties in war just so that we can say that women have had the same chance as men. Women can serve their country in other ways. The bible says no. There is many verses in the holy bible that specifically say that women should not fight in wars. Such as Deuteronomy 22:5 which basically says that men should not wear women clothing and women should not wear the gear of a warrior. Therefore that would mean that women should not fight in the military. The military cannot, and never will be, comparable to modern society. In the civilian life, failing to do your job

 why do we pay national insurance contributions

why do we pay national insurance contributions

If you have a job, then you pay National Insurance. It is taken out of your salary depending on how much you earn, similar to income tax. But because it isn't called a tax, governments can say they haven't increased income tax even though they've put up National Insurance. Labour is planning to increase how much both employers and employees pay. The Conservatives claim that will damage business and say they will scrap the rise. So what is National Insurance and how does it work? National Insurance payments were introduced in 1911. The idea was to provide a government safety-net for workers who fell on hard times. Employees paid money into the scheme out of their wages. Anyone needing cash for medical treatment, or because they had lost their job, could claim from the fund. What it is used
