Yoga and Obesity Control

What is obesity?
---------------------
Excess accumulation of fats (Resulting in increased weight)
In today's technology dominated world, physical activity has
decreased resulting in accumulation of fats. Obesity may become
reason for various other diseases. Obesity is physical, mental
and emotional.

Obesity Symptoms:-
------------------------
Obesity increases weight, reduces physical movements, and also
brings in slowness in emotional and mental activities. Food
intake increases. Obesity can result in frustration.Laziness
increases, reducing overall efficiency. Sometimes obesity can
create obstruction to breathing process. Obesity may result in
heart problems, diabetes or blood pressure.

Yoga and Obesity
----------------------
Yoga has considered all aspects of Obesity (physical, emotional
and mental) Regular practice of Yoga and controlled life style
reduces obesity (weight is reduced). Yoga makes human being
agile, efficient and slim. Yoga is suitable for people in any
age group. Yoga helps to achieve control over mind and behavior
(one can easily control food habits and change life style to
reduce the obesity.)

Sex Really Does Get Better With Age

— An increasing number of 70 year olds are having good sex and more often, and women in this age group are particularly satisfied with their sex lives, according to a study published on the British Medical Journal website.

Knowledge about sexual behaviour in older people (70 year olds) is limited and mainly focuses on sexual problems, less is known about "normal" sexual behaviour in this age group.

Nils Beckman and colleagues from the University of Gothenburg in Sweden, studied attitudes to sex in later life among four representative population samples of 70 year olds in Sweden, who they interviewed in 1971-2, 1976-7, 1992-3, and 2000-1. In total, over 1 500 people aged 70 years were interviewed about different aspects of their sex lives including sexual dysfunctions, marital satisfaction and sexual activity.

The authors found that over the thirty year period the number of 70 year olds of both sexes reporting sexual intercourse increased: married men from 52% to 68%, married women from 38% to 56%, unmarried men from 30% to 54%, and unmarried women from 0.8% to 12%.

In addition, the number of women reporting high sexual satisfaction increased, more women reported having an orgasm during sex and fewer reported never having had an orgasm.

While the proportion of women reporting low satisfaction with their sex lives decreased, the proportion of men reporting low satisfaction increased. The authors suggest that this might be because it is now more acceptable for men to admit "failure" in sexual matters.

They also note that the number of men reporting erectile dysfunction deceased, whereas the proportion reporting ejaculation dysfunction increased, but the proportion reporting premature ejaculation did not change.

Interestingly, both men and women blame men when sexual intercourse stops between them. This finding replicates the results of other studies in the 1950s and 2005-06.
"Our study...shows that most elderly people consider sexual activity and associated feelings a natural part of later life", they conclude.

These findings emphasise the important and positive part sex plays in the lives of 70 year olds and is a welcome contribution to the limited literature about sexual behaviour in older people, writes Professor Peggy Kleinplatz from the University of Ottawa in Canada.

It will hopefully highlight the need for doctors to be trained to ask all patients, regardless of age, about their sexual concerns, she adds.

World's smallest state aims to become the first smoke-free paradise island

It is the world's smallest self-governing state, with a population of just 1,400 and few resources other than fish and coconuts. But the South Pacific island of Niue believes it can set an example by becoming the first country in the world to go smoke-free.

There are about 250 smokers on Niue, a speck of coral with a GDP of barely NZ$6,000 (£2,280) per person, and local officials say the cost of treating smoking-related illnesses is placing a heavy strain on the health budget.


Sitaleki Finau, Niue's director of health, is backing a bill to prohibit smoking and the sale of tobacco in public areas and private homes. The bill has been presented to parliament, but the government has not yet signed up to it. Dr Finau said he expected a ban to face stiff opposition from the tobacco industry and other commercial interests. But he urged MPs to be bold and vote for it.


"Small countries are allowed to be ambitious," he said yesterday. "If a small country can do this, then big countries will start thinking. Imagine what that means." The government would lose revenue from tobacco taxes but that would be more than offset by savings in the health budget, he said.


Like many countries, Niue – which translates as "behold the coconut" – has banned smoking in government offices and public buildings. But outlawing tobacco would be a radical step – particularly on an island so relaxed that, according to one saying, the dogs chase the cats at walking pace.


One village, Tuapa, has already declared itself smoke-free. Tobacco is not sold there, and villagers refrain from smoking in public and during ceremonies.


Dr Finau said the government would have to consider whether a ban infringed smokers' rights. "There has been mixed reaction," he said. "It's one of those difficult political issues, because there are commercial interests against it, and the government has to look at it in relation to tax. A tobacco-free country sounds pretty straightforward and simple, but there are some complex issues involved."


No date has been set for a vote, which could be two years away. Niue, 1,375 miles north-east of Auckland and 312 miles from Tonga, its nearest neighbour, is a former British protectorate. Britain gave it to New Zealand as a reward for the latter's contribution to the Anglo-Boer War, but since 1974 it has been independent "in free association" with Wellington.


Those who live on the island, 100 miles square, regard it as a South Pacific paradise. Beaches are heavenly, crime is non-existent, and the plentiful seafood includes crabs so large that people walk them on leashes. The locals serenade each other on guitars while watching tropical sunsets.
Niue's problem is that, despite all that, everyone is leaving. The population is in steep decline, and some believe it has dropped below a sustainable level.


When Niue was granted independence, its people were given New Zealand citizenship and the chance to emigrate – an offer that now threatens Niue's survival. There are 20,000 Niueans in New Zealand, and those left behind intermittently debate whether the island should rejoin its former colonial ruler.


Successive governments have failed to lure expatriate Niueans home. The island's isolation and lack of resources make for a fragile economy and Niue is heavily dependent on New Zealand aid and foreign remittances. Its main export is taro, a root vegetable. The capital, Alofi, has two shops.


If Niue becomes smoke-free, it may lose another 250 residents. New Zealand's anti-smoking laws are not quite so draconian.

Live Longer: The One Anti-Aging Trick That Works

While the quest for the proverbial Fountain of Youth is endless and typically fruitless, one method known to extend the human lifespan by up to five years has quietly become accepted among leading researchers.

The formula is simple: Eat less. It could add years to your life, several experts now say. And done in moderation, it could at least help you live a more healthy life.

The only question is: Will the average person do it?

While little short of a nip-and-tuck will make you look younger, calorie restriction, as it is called, is as close to a real Fountain of Youth as any known technique comes. Even scientists who are cautious about anti-aging hype say it works, both by cutting risks for some diseases and by allowing all body cells, somehow, to hang in there longer.

"There is plenty of evidence that calorie restriction can reduce your risks for many common diseases including cancer, diabetes and heart disease," says Saint Louis University researcher Edward Weiss, who last week announced a new study that brings fresh understanding to how it works. "And you may live to be substantially older."

The numbers

Here's a rough rule of thumb that many experts generally agree on now: Eat 15 percent less starting at age 25 and you might add 4.5 years to your life, says Eric Ravussin, who studies human health and performance at the Pennington Biomedical Research Center in Louisiana.
One important caveat: Ravussin's estimate is based mostly on studies of other animals and only preliminary research in humans. But the work by Weiss and others is unlocking the mysteries of aging and suggesting the animal studies apply to humans.

"There is absolutely no reason to think it won't work," Ravussin told LiveScience.

Perhaps even more promising, though in early stages of research, are drugs designed on the basis of what's been learned from calorie-restriction studies. Those drugs would target human cells to deliver the same benefits, turning off bad things and turning on good things to extend cell life in general, or offer new therapies and cures to vexing diseases like Alzheimer's and cancer.
If you can hang in there until these promising new drug therapies are developed, you may live in a world where lifespan increases by 10 to 15 years, researchers say.

Don't plan on living to be 200, Ravussin said, "but I think we're going to gain quite a few years."
Mysteries remain

Scientists aren't sure exactly why calorie restriction slows aging. But they're on the verge of a firm understanding. In a nutshell, it is thought to lower metabolic rate and cause the body to generate fewer damaging "free radicals."

One hypothesis is that it decreases a thyroid hormone, triiodothyronine (T3), which then slows metabolism and tissue aging.

Weiss and colleagues studied men and women, aged 50 to 60, who did not smoke, were not obese and were in good health. The volunteers were split into three groups - a calorie-restriction group, an exercise group, or a control group - and followed for one year. The calorie-restriction group cut back by 300 to 500 calories per day. (A typical healthy adult diet should include about 2,000 calories.) Volunteers in the exercise group maintained their regular diet and exercised regularly.

While both the calorie-restriction and exercise groups experienced similar changes of body fat mass, only those in the calorie restriction group also experienced lower levels of the thyroid hormone. A longer-term study is still needed to pin down whether reducing T3 levels through calorie restriction indeed slows the aging process as suspected, the scientists say.

The results were published in the June issue of the journal Rejuvenation Research.

Step-by-step

Weiss' work advances the body of anti-aging knowledge, said Christy Carter, an aging researcher and assistant professor at the University of Florida College of Medicine.

"The more that scientists can demonstrate similar biological profiles between rodents and humans with regards to calorie restriction, the greater the possibility that lifespan extension will translate to human as well," Carter said.

Weiss figured it's sensible to take steps now. You can cut 300 to 500 calories by simply skipping dessert or substituting a turkey sandwich for fast food. A nutritional diet and exercise are important to any weight-loss effort, Weiss and others caution.

"Our research provides evidence that calorie restriction does work in humans like it has been shown to work in animals," Weiss said. "The next step is to determine if this in fact slows age-related tissue deterioration. The only way to be certain, though, is to do a long-term study."
Others agree: more research is needed.

"I think that they've documented a real and interesting effect of caloric restriction in humans," said UCLA evolutionary biologist Jay Phelan. "But they are still a long way from demonstrating that it changes human lifespan at all."

Proven in animals

Evidence that calorie restriction boosts lifespans in rodents is solid. Christiaan Leeuwenburgh of the University of Florida's Institute on Aging showed in 2006 that eating just 8 percent less and exercising a little more over a lifespan can reduce or even reverse aging-related cell and organ damage in rats.

Various studies have shown that cutting calories by 20 to 40 percent significantly both extends life and, with a little exercise, leaves old animals in better shape.

Eating fewer calories also reduces age-related chronic diseases such as cancers, heart disease, and stroke in rodents. That's important because it suggests ways to not just make us live longer, but to allow us to age more gracefully, healthwise.

Research last year found that rats on a restricted diet are more physically fit in old age, apparently slowing the typical onset of physical disability. The rodents also looked and probably felt better: "Rats that ate a normal diet lost a significant amount of lean muscle mass and acquired more fat, while calorie-restricted rats maintained lean muscle mass as they aged," said lead researcher Tongjian You from the University of Buffalo. The finding was published in the October issue of the Journals of Gerontology Series A: Biological Sciences and Medical Sciences.
Rodents are thought to be good analogues to humans. Dogs are even better.

A 14-year study of 48 Labrador Retrievers found restricting their diets by 25 percent starting at 8 weeks of age extended their lives by an average of 1.8 years. For a creature that typically never gets beyond its early teens, that's a big number. The findings were published back in 2002 in the Journal of the American Veterinary Medical Association.

"The study also showed that lean body conformation forestalls some chronic illnesses, most notably osteoarthritis," said University of Pennsylvania researcher Gail K. Smith, who worked on the dog study. Ailments typically struck the lean dogs 2.1 years later than the others.
Probably works in humans

Convincing humans to eat less, and then studying the effects over a lifetime, is considerably more challenging. But mounting research suggests that what works for rats and dogs seems to apply to people.

Studies are under way with monkeys, which have lifespans of around 25 to 30 years, and early indications are promising, Ravussin said.

A study of humans last year found that cutting calories in human test subjects reduced oxidative damage in muscle cells. In the journal PLoS Medicine, the researchers speculated that the effect might translate into longer life.

Researchers caution, however, that longer lifespans does not mean immortality. The vast majority of mainstream researchers envision lifespans extending a few years.

"My estimate would be that 40 years of caloric restriction would give a 3 to 7 percent increase in longevity, so an optimistic estimate would be an additional four years or so," said Phelan, the UCLA researcher.

But researchers are quick to point out that human nature is not conducive to life-long calorie-restriction diets. "It's going to be limited to a few people who are going to try to do that," Ravussin said.

Seeking balance

"Suffering years of misery to remain super-skinny is not going to have a big payoff in terms of a longer life," Phelan said back in 2005 when the idea of "living forever" was particularly hyped in the media. "I once heard someone say caloric restriction may not make you live forever, but it sure would seem like it. Try to maintain a healthy body weight, but don't deprive yourself of all pleasure. Moderation appears to be a more sensible solution."

Phelan uses rodents as an example of why caution is warranted:
Mice will live longer if their diet is restricted by 10 percent, he said in 2005. "If you restrict their intake by 20 percent, they live even longer, and restrict them to 50 percent, they live longer still. But restrict their intake by 60 percent and they starve to death."

In an email interview the other day, Phelan said he stands by this assessment.

And Phelan now thinks there is "nothing" on the research horizon "that would extend lifespan in a significant amount, on the order of 10 or more years."

Big promise?

Other experts are optimistic that research into calorie restriction will lead to greater things.
Scientists are investigating what they call CR mimetics, or compounds that mimic the effects of calorie restriction. "This includes naturally occurring compounds and pharmaceuticals," explained Carter, the University of Florida researcher. "One that has received much attention lately is a compound called resveratrol, found in red wine."

Researchers have long pondered the French paradox: The French eat high-fat diets but live relatively long lives. Resveratrol and other compounds in red wine are thought by many to contribute to that good life. But testing any anti-aging drug or therapy sets up another tricky paradox: Nobody wants to invest in a 70-year test, and the Food and Drug Administration won't approve a chemical's use without thorough testing. There's a potential shortcut: Researchers are testing compounds thought to thwart aging on Alzheimer's patients to see if they slow the degradation of neurons. And similar human trials will begin soon on diabetes patients.

"However, many of these studies are still in the development phase, still being tested in rodent models," Carter said. "I expect that this field will begin to explode in the next few years. Caution is still merited given the need for extensive study of these compounds as to their efficacy and long-term safety."

Eventually, Ravussin thinks the combined efforts of all these research angles could extend lifespans by 15 years later this century.

In a society where lifespan has already increased significantly in recent decades, many people are at least as concerned with aging well as they are with living long.

"Many researchers are focusing on the effects of CR on health-span as opposed lifespan," Carter said. "We know that small reductions in caloric intake, even as little as 8 percent, result in improvements in health related outcomes."

Blocking Sun Not Feasible Warming Solution, Says Study



July 7, 2008 -- A proposal to reverse climate change by placing mirrors in the sky to reflect sunlight away from Earth won't give us back the same climate we had before we started emitting so much carbon dioxide, says a new study.
Researchers at the University of Bristol in the United Kingdom applied state-of-the-art global climate models to predict the effect of using reflective sunshades to send a fraction of the sunlight that enters Earth's atmosphere back into space before it can heat things up.
They compared two futures with four times the pre-industrial level of CO2: one where nothing was done, and another where the sunlight intensity was reduced to a level that achieved the lower, pre-industrial global average temperature, despite the higher CO2 levels.
The second case simulated the use of enough sunshades to drop the average temperature to pre-industrial levels, which turned out to be a reduction in sunlight of about 4.2 percent.
"Although we managed to cancel out warming on a global average, what you end up with is some areas that warm up and some that cool down," said Dan Lunt, who led the study, published in Geophysical Research Letters.
"We found warming in the Arctic and Antarctic regions, and a cooling in the equatorial regions," Lunt said. "We got a decrease in rainfall a lot of places in the world, decreases in sea ice, and some changes in the El Nino phenomenon."
These changes resulted because the mirrors reduce sunlight more at the equators than near the poles, while CO2 has a warming effect that's more equally distributed, Lunt said.
The sunshades also do nothing to prevent changes caused by increased CO2, such as ocean acidification or changes to plant growth.

Although the sunshade approach won't bring back the same climate as reducing CO2 emissions, "it is highly successful compared to doing nothing," Lunt adds.
Lunt's team's work was not the first to try to understand the effects of sunshades using a climate model. Work by Ken Caldeira of the Carnegie Institution in Stanford, Calif., also modeled a "sunshade world," but with a less complex model that did not include complete accounting for ocean circulation and sea ice.
"The study confirms our earlier findings with a better model," Caldeira said.
Although Lunt's model suggests sunshades are better than nothing, he would rather see efforts focused elsewhere.
"My personal opinion is that we should be focusing our time and money on actually reducing emissions," he said, "rather than some manmade monstrosity in space."
"The biggest problem I have with geoengineering discussions now is that the prospect of it working will reduce efforts to mitigate the problem by reducing fossil fuel emissions," agreed climatologist Alan Robock of Rutgers University in New Brunswick, N.J.
"The solution to the climate problem is mitigation, not geoengineering," he added. "These things are not perfect and there's the potential for unintended consequences."

Ignite your passion for business

Running a business is extremely demanding. It's constantly on your mind whether you are actually at work or not. This obviously increases our stress levels, which can lead to tiredness and lack of motivation. Even the most enthusiastic business owner or business professional can have their "down" days. This is the time for you to recharge your batteries and return to your business refreshed and excited, otherwise you run the risk of passing on your lack of motivation to your staff and colleagues.

Tips to help you keep motivated and inspired:
> Attend a personal development seminar. Discover an area in your business or personal life that you would like to improve. There are training programs, night courses, and even weekend seminars that can boost your energy levels and get you re-focused.
> Join a business networking event. Meeting with other business people can help you see your business in a different light. It gives you the opportunity to talk about all the great things your business has to offer. Talking with a new business contact is interesting, informative and inspiring. The energy in the room at a networking event is uplifting and stimulating. Just what you need to perk you up!
> Take a break. With mobile technology being so accessible we think that we should also work a little while on vacation. However, the only true way to come back to work with renewed energy is to give your mind & body a total break. There is plenty of time to catch up on emails etc when you get back. So unplug yourself completely and enjoy a break every few months!
> Exercise. Regular exercise helps your body work more effectively and efficiently. Many people think about their work or business while exercising and solutions usually come more easily with blood pumping through your veins. Give it a go. Even a walk around the block at lunchtime can get the creative juices flowing.
> Listen to a motivational CD. Try listening to a motivational or inspiring CD in your car on the way to work instead of listening to the radio. That way you will arrive at work motivated and ready to get on with business rather than feeling depressed about the daily news bulletin!
> Surround yourself with positive people. Positive and optimistic people will uplift your spirits and help keep you motivated. They give you energy and focus rather than draining it from you.

The scientific method to being "sexy"


Allure's new sex issue is out, and I love, love, love all the juicy details. My favorite piece is called "The Laws of Attraction," in which they ask different experts to define "What is sexy?" according to the fields they work in, which are, anthropology, scent, science and acting. You'll have to buy the magazine to get the whole story, but here's the gist of what they're saying:

The Anthropologist:

"...large breasts, a small waist, and wide hips. This is a holdover from times when women with wider hips were more likely to survive childbirth...full, red lips and a clear complexion..."

The bottom line: So basically, Angelina Jolie.

The Scent Expert:

"Research tells us that our body odor plays a role in whether we're truly attracted to someone...we've heard accounts from thousands of men and women who say that they were attracted to their partner because they just smelled right."

The bottom line: Spicy perfume may smell like seduction, but at the end of the day, it's all about your natural scent.

The Scientist:

"Women are beginning to understand there's no such thing as 'normal'...the kind of behavior we know for sure leads to a satisfying sex life is mixing in other activities that bring you pleasure--whether it's listening to music during sex, or eating certain foods beforehand."

The bottom line: In other words, be yourself. And celebrate your late night Ben & Jerry's addiction.

The Acting Coach:

"In Hollywood, physical beauty is everywhere, but sexiness is not...voice is extremely important...Today, many young actresses talk like little girls, and there is nothing sensual or attractive about that...Women are supposed to grow up--only then can they truly captivate.

"The bottom line: Don't be afraid to be a woman. Grr...
