Obese have poorer sex life: study
PARIS (AFP) - – Obese women are likelier to neglect contraception, obese men are more prone to impotence and both are far less sexually active than counterparts of normal weight, a study said on Wednesday.
The findings highlight "a major reproductive health challenge," requiring doctors to pierce the twin taboos of obesity and sex, it said.
The research covered 10,170 men and women aged 18-69 whose data was randomly chosen from a French survey of sexual behaviour carried out in 2006.
Around two-thirds were of normal weight, a quarter were overweight and the remainder (411 women and 350 men) were obese.
Overweight was defined by having a body mass index (BMI) of between 25 and 30, and obesity as a BMI of at least 30.
Obese women were 29 percent less likely to have had a sex partner in the previous 12 months, compared with women of normal weight.
Obese men were 69 percent less likely to report having more than one sexual partner in the same period and two and a half times likelier to report erection problems than non-obese counterparts. Obese men under 30 were also far likelier to have a sexually-transmitted disease.
Sexual dysfunction -- lack of desire or arousal or pain in intercourse -- was not a problem for obese women.
However, those under 30 were far likelier not to use contraception or to seek contraceptive advice. Unintended pregnancies among obese women were more than four times higher than among women of normal weight.
That discovery is especially worrying, as obesity is a major factor in mother and infant death and sickness.
The study, published online by the British Medical Journal (BMJ), was headed by Nathalie Bajos of the National Institute of Health and Medical Research (Inserm) in Paris.
In a commentary published by the BMJ, Sandy Goldbeck-Wood, a British gynaecologist specialising in psychosexual medicine, said the findings should ring alarm bells, given the unfurling global epidemic of obesity.
"In public health terms, the study lends a new slant to a familiar message: that obesity can harm not only health and longevity, but your sex life. And culturally, it reminds us clinicians and researchers to look at the subjects we find difficult."
BMI is derived by dividing one's weight in kilograms by the square of one's height in metres. Using Imperial or US measurements, it is one's weight in pounds multiplied by 703, and then divided by the square of one's height in inches.

Now We Know Why US Is Adamant To Conquer Afghanistan...
WASHINGTON – A team of U.S. geologists and Pentagon officials has discovered vast mineral wealth in Afghanistan, conceivably enough to turn the scarred and impoverished country into one of the world's most lucrative mining centers, The New York Times reports.
"There is stunning potential here," Gen. David H. Petraeus, commander of the United States Central Command, told the paper in a report published Monday. "There are a lot of ifs, of course, but I think potentially it is hugely significant."
Americans discovered nearly $1 trillion in untapped mineral deposits in Afghanistan, including iron, copper, cobalt, gold and critical industrial metals like lithium, according to the report. The Times quoted a Pentagon memo as saying Afghanistan could become the "Saudi Arabia of lithium," a key raw material in the manufacture of batteries for laptops and cell phones.
The report said the U.S. Geological Survey began aerial surveys of Afghanistan's mineral resources in 2006, using data that had been collected by Soviet mining experts during the Soviet occupation of Afghanistan in the 1980s. Promising results led to a more sophisticated study the next year.
Then last year, a Pentagon task force that had created business development programs in Iraq arrived in Afghanistan and closely analyzed the geologists' findings. U.S. mining experts were brought in to validate the survey's conclusions, and top U.S. and Afghan officials were briefed.
So far, the biggest mineral deposits discovered are of iron and copper, but finds include large deposits of niobium, a soft metal used in producing superconducting steel, as well as rare earth elements and large gold deposits in Pashtun areas of southern Afghanistan, the report said.

Mars Hoax Circulates: 'Big as the Moon!'
– Wed May 20, 3:51 pm ET
Once again it appears that a Mars hoax that has widely circulated through the Internet since its first appearance during the summer of 2004 has begun to circulate yet again. It comes in the form of an e-mail message titled "Mars Spectacular," which originated from an unknown source.
In turn, this message has gotten passed on to others who couldn't resist forwarding it to their entire address book.
The e-mail declares that on the night of Aug. 27, the planet Mars will come closer to Earth than it has in the past 60,000 years, thereby offering spectacular views of the Red Planet. The commentary even proclaims, with liberal use of exclamation marks, that Mars will appear as bright as (or as large as) the full moon.
The problem is that "Aug. 27" is actually Aug. 27, 2003. Mars made a historically close pass by Earth that night (34.6 million miles, or 55.7 million km). The Hubble Space Telescope used the opportunity to make a great photo of Mars. But even then, to the naked eye Mars appeared as nothing more than an extremely bright yellowish-orange star, not at all like the full moon.
This year, Mars is actually much dimmer and far-less conspicuous than in 2003.
You can find Mars in the early morning sky right now, however, located not far from the dazzling planet, Venus. This week, the moon serves as a guide to spotting the red planet -- and you can easily compare them to see just how different they appear in size.
"In the past, the rapid spread of this information was like some sort of brain info-virus, and led to at least one daily newspaper comic that showed Mars crashing into a home while the husband and wife were indoors, debating how close the planet will come," said Neil deGrasse Tyson, director of New York's Hayden Planetarium.
In terms of actual size, Mars (approximately 4,213 miles, or 6,780 km. in diameter) is almost twice the size of our moon (about 2,160 miles, or 3,475 km). But the great distance between Mars and Earth never allows it to appear anywhere near as large as the moon in our sky.
The average distance of the moon from Earth is 238,000 miles (382,900 km). So for Mars to appear to loom as large as the Moon does from Earth, it would have to be about twice the Moon's distance, or roughly 476,000 miles (766,000 km.).
In fact, right now the red planet remains is 189 million miles (304 million km) from Earth.
So, plain and simple, if you have already received this infamous Mars E-mail -- or eventually receive it this summer -- be advised that it is totally bogus.
Or Tyson suggests: "Now it's time for you to send this antidote to all the infected people in your address book!"

Scientists discover deadly secret of Komodo's bite
It had been widely believed that deadly bacteria in the carnivorous lizard's mouth helped kill its prey.
But magnetic resonance imagery has for the first time uncovered venom glands containing a shock-inducing poison which increases blood flow and decreases blood pressure, scientists say.
Lead researcher Bryan Fry said three-dimensional computer imaging comparing the Komodo's bite with that of Australia's saltwater crocodile showed it used a "grip and rip" pulling manoeuvre to tear deep wounds, similar to a shark or sabre cat.
Fry surgically removed a venom gland from a terminally ill Komodo at Singapore Zoo for the study, and said it contained a highly toxic poison which would induce potent stomach cramps, hypothermia and a drop in blood pressure.
The venom also blocked the blood's clotting ability, he said.
"Such a fall in blood pressure would be debilitating in conjunction with blood loss and would render the envenomed prey unable to escape," he said.
"These results are congruent with the observed unusual quietness and apparent rapid shock of prey items."
Komodos are the world's heaviest lizard, typically weighing 70 kilograms (150 pounds) and growing up to three metres (10 feet) in length.
They are native to several Indonesian islands and are considered a vulnerable species, with only a few thousand left in the world.
They live on a diet of large mammals, reptiles and birds but have been known to attack humans.
An Indonesian fisherman was in March mauled to death by a Komodo dragon after he ventured into a remote island sanctuary for the giant killer lizards.

Pandemic Flu: Swine Influenza.
3. Other symptoms may include:
- headache
- tiredness
- chills
- aching muscles
- sore throat
- runny nose
- sneezing
- loss of appetite.
4. The incubation period
1 to 4 days, though for most people it will be two to three days
5. The infectious period
People are most infectious soon after they develop symptoms. They can continue to spread the virus, for example in coughs and sneezes, for up to five days (seven days in children). People become less infectious as their symptoms subside, and once symptoms are gone,they are considered no longer infectious to others.
6. Prudent Practice :
A) Where social interactions and attendance areunavoidable, considerations might be given toasking the individual with symptoms consistent toFlu to adopt practices that reduce the risk ofinfecting others
B) individuals with signs of flu or cough should beencouraged to wear face masks
Last but not least , as a precaution, if your organization had staff who travelled to Mexico in the last 2 (two) weeks, and more recently US, your co-operation is appreciated in informing the relevant authority. This is to ensure that relevant authority can respond promptly and appropriately, thereby reducing the risk of healthy /susceptible people succumbing or being infected by the flu virus.
