Has he found his princess this time?

Prince Harry has reportedly rekindled his romance with Cressida Bonas, a British model and society girl with whom he was briefly linked to last summer, according to the Daily Mail, which published a photo of them embracing during a recent ski vacation.

According to various British papers, the couple have been enjoying a PDA-filled trip in the Swiss Alps this week – joining Harry's uncle, Prince Andrew, for his 53rd birthday celebrations.

Andrew's daughter, Princess Eugenie, who is also along for the trip – along with her sister Beatrice and her mother Sarah, Duchess of York – was the one who introduced Bonas to Harry in the first place.

Blonde like Chelsy Davy, Harry's most notable ex, Bonas, 24, is the daughter of Lady Mary-Gaye Georgiana Lorna Curzon, the half-sister of actress Isabella Anstruther-Gough-Calthorpe, who is engaged to Richard Branson's son Sam.

Harry and Bonas also flew together to the Caribbean island of Necker last summer for Sam Branson's birthday.

Their relationship cooled after Harry's notorious naked antics in Las Vegas last August, according to the British press.

Harry, 28, returned last month from Afghanistan, where he had been serving as a captain and Apache helicopter co-pilot gunner.

Adults get 11 percent of calories from fast food

ATLANTA (AP) — On an average day, U.S. adults get roughly 11 percent of their calories from fast food, a government study shows.

That's down slightly from the 13 percent reported the last time the government tried to pin down how much of the American diet is coming from fast food. Eating fast food too frequently has been seen as a driver of America's obesity problem.

For the research, about 11,000 adults were asked extensive questions about what they ate and drank over the previous 24 hours to come up with the results.

Among the findings:

— Young adults eat more fast food than their elders; 15 percent of calories for ages 20 to 39 and dropping to 6 percent for those 60 and older.

— Blacks get more of their calories from fast-food, 15 percent compared to 11 percent for whites and Hispanics.

— Young black adults got a whopping 21 percent from the likes of Wendy's, Taco Bell and KFC.

The figures are averages. Included in the calculations are some people who almost never eat fast food, as well as others who eat a lot of it.

The survey covers the years 2007 through 2010 and was released Thursday by the Centers for Disease Control and Prevention. The authors couldn't explain why the proportion of calories from fast food dropped from the 13 percent found in a survey for 2003 through 2006.

One nutrition professor cast doubts on the latest results, saying 11 percent seemed implausibly low. New York University's Marion Nestle said it wouldn't be surprising if some people under-reported their hamburgers, fries and milkshakes since eating too much fast food is increasingly seen as something of a no-no.

"If I were a fast-food company, I'd say 'See, we have nothing to do with obesity! Americans are getting 90 percent of their calories somewhere else!'" she said.

The study didn't include the total number of fast-food calories, just the percentage. Previous government research suggests that the average U.S. adult each day consumes about 270 calories of fast food — the equivalent of a small McDonald's hamburger and a few fries.

The new CDC study found that obese people get about 13 percent of daily calories from fast food, compared with less than 10 percent for skinny and normal-weight people.

There was no difference seen by household income, except for young adults. The poorest — those with an annual household income of less than $30,000 — got 17 percent of their calories from fast food, while the figure was under 14 percent for the most affluent 20- and 30-somethings with a household income of more than $50,000.

That's not surprising since there are disproportionately higher numbers of fast-food restaurants in low-income neighborhoods, Nestle said.

Fast food is accessible and "it's cheap," she said.

Wall Street falls after raft of weak data

NEW YORK (Reuters) - U.S. stocks declined on Thursday as a ream of weak economic data did little to assuage some investors' concerns that the Federal Reserve may rein in its economic stimulus measures and amid uncertainty over ongoing budget talks in Washington.

The number of Americans filing new claims for unemployment benefits rose last week and consumer prices were flat in January, buttressing the argument for the Fed to continue its accommodative monetary policy.

On Wednesday, minutes from the U.S. Federal Reserve's most recent meeting suggested the central bank may slow or stop buying bonds sooner than expected. The news sent shares lower and the benchmark S&P 500 index dropped 1.2 percent, its biggest decline since November 14.

The Fed has used quantitative easing, or QE, since 2008 in a bid to stimulate the economy. The policy, which involves expanding the Fed's balance sheet to buy bonds, has been credited with pushing money into the stock market, and its withdrawal would remove a ballast for the markets.

The benchmark S&P index has dropped 1.9 percent over the past two sessions but is still up more than 5 percent for the year. That's led many analysts to believe that the Fed minutes, the upcoming sequestration in Washington and sluggish consumer spending may be triggers for an overdue pullback in equities.

The sequestration - automatic across-the-board spending cuts put in place as part of a larger congressional budget fight - are due to kick in March 1 unless lawmakers agree on an alternative.

"It's the sequester, it's the knee-jerk reaction to yesterday's Fed minutes and it's the realization the consumer is slowing," said Phil Orlando, chief equity market strategist, at Federated Investors, in New York.

"I'd love to see a healthy 5 percent correction; let's wash out some of the weak hands and set up for a better move during the year."

Financial data firm Markit said its "flash," or preliminary U.S. Manufacturing Purchasing Managers Index slowed to 55.2 this month from 55.8, which had been the best showing since April, 2012.

Wal-Mart Stores Inc , seen as a gauge of consumer spending, said U.S. sales weakness persisted into early February, as Americans absorbed the impact of higher payroll taxes and gasoline prices, along with slow tax refunds that put some spending on hold. But shares rose 2.2 percent to $70.73 to help curb declines on the Dow as earnings topped expectations.

The Dow Jones industrial average <.dji> dropped 64.01 points, or 0.46 percent, to 13,863.53. The Standard & Poor's 500 Index <.spx> lost 10.33 points, or 0.68 percent, to 1,501.62. The Nasdaq Composite Index <.ixic> fell 25.93 points, or 0.82 percent, to 3,138.48.

In a positive sign, data showed home resales edged higher in January and left inventory of homes at its lowest level in 13 years as the housing market continues to steadily improve.

But the Federal Reserve Bank of Philadelphia said its index of business conditions in the U.S. Mid-Atlantic region fell in February to minus 12.5, the lowest level in eight months, from minus 5.8 in January.

VeriFone Systems Inc tumbled 37.7 percent to $19.86 after the credit card swipe-machine maker forecast first and second-quarter profit that were well below analysts' expectations.

According to Thomson Reuters data through Thursday morning, of the 427 companies in the S&P 500 that have reported results, 69.3 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.9 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Berry Petroleum Co jumped 16.5 percent to $444.95 after oil and gas producer Linn Energy LLC said it would buy the company in an all-stock deal valued at $4.3 billion including debt. Linn Energy shares advanced 3 percent to $37.76.

Bulgarian government resigns amid growing protests

SOFIA (Reuters) - Bulgaria's government resigned on Wednesday after mass protests against high power prices and falling living standards, joining a long list of European administrations felled by austerity during four years of debt crisis.

Prime Minister Boiko Borisov, an ex-bodyguard who took power in 2009 on pledges to root out graft and raise incomes in the European Union's poorest member, faces a tough task of propping up eroding support ahead of an expected early election.

Wage and pension freezes and tax hikes have bitten deep in a country where earnings are less than half the EU average and tens of thousands of Bulgarians have rallied in protests that have turned violent, chanting "Mafia" and "Resign".

Moves by Borisov on Tuesday to blame foreign utility companies for the rise in the cost of heating homes was to no avail and an eleventh day of marches saw 15 people hospitalized and 25 arrested in clashes with police.

"My decision to resign will not be changed under any circumstances. I do not build roads so that blood is shed on them," said Borisov, who began his career guarding the Black Sea state's communist dictator Todor Zhivkov.

A karate black belt, Borisov has cultivated a Putin-like "can-do" image since he entered politics as Sofia mayor in 2005 and would connect with voters by showing up on the capital's rutted streets to oversee the repair of pot-holes.

But critics say he has often skirted due process, sometimes to the benefit of those close to him, and his swift policy U-turns have wounded the public's trust.

The spark for the protests was high electricity bills, after the government raised prices by 13 percent last July. But it quickly spilled over into wider frustration with Borisov and political elites with perceived links to shadowy businesses.

"He made my day," said student Borislav Hadzhiev in central Sofia, commenting on Borisov's resignation. "The truth is that we're living in an extremely poor country."

POLLS, PRICES

The prime minister's final desperate moves on Tuesday included cutting power prices and risking a diplomatic row with the Czech Republic by punishing companies including CEZ, moves which conflicted with EU norms on protection of investors and due process.

CEZ officials were hopeful on Wednesday that it would be able to avoid losing its distribution license after all and officials from the Bulgarian regulator said the company would not be punished if it dealt with breaches of procedure.

But shares in what is central Europe's largest publicly-listed company fell another 1 percent on Wednesday.

If pushed through, the fines for CEZ and two other foreign-owned firms will not encourage other investors in Bulgaria, who already have to navigate complicated bureaucracy and widespread corruption and organized crime to take advantage of Bulgaria's 10-percent flat tax rate.

Financial markets reacted negatively to the turbulence on Wednesday. The cost of insuring Bulgaria's debt rose to a three-month high and debt yields rose some 15 basis points, though the country's low deficit of 0.5 percent of gross domestic product means there is little risk to the lev currency's peg against the euro.

Borisov's interior minister indicated that elections originally planned for July would probably be pulled forward by saying that his rightist GERB party would not take part in talks to form a new government.

MILLIONS GONE

GERB's woes have echoes in another ex-communist EU member, Slovenia, where demonstrators have taken to the streets and added pressure to a crumbling conservative government.

A small crowd gathered in support of Borisov outside Sofia's parliament, which is expected to approve his resignation on Thursday, while bigger demonstrations against the premier were expected in the evening.

Unemployment in the country of 7.3 million is far from the highs hit in the decade after the end of communism but remains at 11.9 percent. Average salaries are stuck at around 800 levs ($550) a month and millions have emigrated, leaving swathes of the country depopulated and little hope for those who remain.

GERB's popularity has held up well and it still led in the latest polls before protests grew in size last weekend, but analysts say the opposition Socialists should draw strength from the demonstrations.

The leftists, successors to Bulgaria's communist party, have proposed tax cuts and wage hikes and are likely to raise questions about public finances if elected.

Why Miranda Lambert's First Rescue Dog Won't Tour with Her Anymore

Miranda Lambert has no shortage of groupies when she takes her act on the road. But there's one special fan she won't be seeing anymore when on tour: her dog Delilah.

"Delilah was my first rescue dog, and she went everywhere," Lambert tells CMT of her terrier mix. "But she's kind of retired from the road at this point."

These days, Delilah, just one member of Lambert's ever-expanding menagerie of mutts, stays with the country crooner's grandmother. "[Delilah]'s just over it," Lambert says.

Still hanging onto their backstage passes: Cher the Chihuahua and Delta the Chihuahua-pug mix. "They're little bitty dogs," she says, "so it's easy to maneuver them."

Her furry fans are a testament to her love of animals; just last month, the singer helped launch The Pedigree Feeding Project, a new initiative to supply one pet shelter in a worthy community with a year's supply of dog food.

"Our dogs probably run our life a little more than they should, truth be known," adds Lambert, who's married to fellow country star Blake Shelton. "But with rescues, you make up for lost time. And ours have the best life now."

Future science: Using 3D worlds to visualize data

CHICAGO (AP) — Take a walk through a human brain? Fly over the surface of Mars? Computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality with a wraparound virtual world where a researcher wearing 3D glasses can do all that and more.

In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from 72 stereoscopic liquid crystal display panels, conveying a dizzying sense of being able to touch what's not really there.

As far back as 1950, sci-fi author Ray Bradbury imagined a children's nursery that could make bedtime stories disturbingly real. "Star Trek" fans might remember the holodeck as the virtual playground where the fictional Enterprise crew relaxed in fantasy worlds.

The Illinois computer scientists have more serious matters in mind when they hand visitors 3D glasses and a controller called a "wand." Scientists in many fields today share a common challenge: How to truly understand overwhelming amounts of data. Jason Leigh, co-inventor of the CAVE2 virtual reality system, believes this technology answers that challenge.

"In the next five years, we anticipate using the CAVE to look at really large-scale data to help scientists make sense of that information. CAVEs are essentially fantastic lenses for bringing data into focus," Leigh said.

The CAVE2 virtual world could change the way doctors are trained and improve patient care, Leigh said. Pharmaceutical researchers could use it to model the way new drugs bind to proteins in the human body. Car designers could virtually "drive" their new vehicle designs.

Imagine turning massive amounts of data — the forces behind a hurricane, for example — into a simulation that a weather researcher could enlarge and explore from the inside. Architects could walk through their skyscrapers before they are built. Surgeons could rehearse a procedure using data from an individual patient.

But the size and expense of room-based virtual reality systems may prove insurmountable barriers to widespread use, said Henry Fuchs, a computer science professor at the University of North Carolina at Chapel Hill, who is familiar with the CAVE technology but wasn't involved in its development.

While he calls the CAVE2 "a national treasure," Fuchs predicts a smaller technology such as Google's Internet-connected eyeglasses will do more to revolutionize medicine than the CAVE. Still, he says large displays are the best way today for people to interact and collaborate.

Believers include the people at Marshalltown, Iowa-based Mechdyne Corp., which has licensed the CAVE2 technology for three years and plans to market it to hospitals, the military and in the oil and gas industry, said Kurt Hoffmeister of Mechdyne.

In Chicago, researchers and graduate students are creating virtual scenarios for testing in the CAVE2. The Mars flyover is created from real NASA data. The brain tour is based on the layout of blood vessels in a real patient.

Brain surgeon Ali Alaraj remembered the first time he viewed the brain using the CAVE2.

"You can walk between the blood vessels," said the University of Illinois College of Medicine neurosurgeon. "You can look at the arteries from below. You can look at the arteries from the side.... That was science fiction for me."

Would doctors process information faster with fewer errors using CAVE2? That's the question behind a proposed study that would compare CAVE2 to conventional methods of detecting brain aneurysms and determining proper treatment, said Andreas Linninger, UIC professor of bioengineering, chemical engineering and computer science.

But it's not all serious business at the lab.

In his spare time during the past two years, research assistant Arthur Nishimoto has been programming the CAVE2 computer with the specifications for the fictional Starship Enterprise. He now can walk around his life-size recreation of the TV spacecraft.

The original technology, introduced in the early 1990s, was called CAVE, which stood for Cave Automatic Virtual Environment and also cleverly referred to Plato's cave, the philosopher's analogy about shadows and reality. It was named by former lab co-directors Tom DeFanti and Dan Sandin.

The second generation of the CAVE, invented by Leigh and his collaborator Andy Johnson, has higher resolution. The project was funded by the National Science Foundation and the Department of Energy.

"It's fantastic to come to work. Every day is like getting to live a science fiction dream," Leigh said. "To do science in this kind of environment is absolutely amazing."

Wall Street little changed after data, Fed minutes on tap

NEW YORK (Reuters) - Stocks were little changed on Wednesday after housing and inflation data pointed to a continuation of modest economic improvement and ahead of the minutes from the Federal Open Market Committee's January meeting later in the session.

Groundbreaking to build new U.S. homes fell 8.5 percent in January but new permits for construction rose to a 4 1/2-year high while producer prices rose in January for the first time in four months.

The data should enable the Fed to maintain its easy monetary policy in its efforts to stimulate the economy.

Later in the session, investors will look to the minutes from the Fed's January meeting for any indication as to how long the current monetary policy will remain in effect.

"It's hard in any given data point to take a strong conclusion that we are moving dramatically forward, but over time, clearly things are getting better," said Robert Lutts, chief investment officer at Cabot Money Management in Salem, Massachusetts.

Lutts described an economy that was addicted to stimulus.

"The bottom line is the economy is on heroin today and we will at one time move to a diluted form of heroin, but it's very important for people to remember we are still on an unbelievably aggressive, never-seen-before accommodative policy and this economy is going to improve."

The S&P 500 <.spx> is up more than 7 percent for the year, fueled by legislators' ability to sidestep an automatic implementation of spending cuts on tax hikes on January 1, better-than-expected corporate earnings and modestly improving economic data that has been tepid enough for the Fed to maintain its stimulus policy.

The Dow Jones industrial average <.dji> dropped 5.99 points, or 0.04 percent, to 14,029.68. The Standard & Poor's 500 Index <.spx> lost 2.60 points, or 0.17 percent, to 1,528.34. The Nasdaq Composite Index <.ixic> shed 3.12 points, or 0.10 percent, to 3,210.48.

U.S. oil and gas producer Devon Energy Corp reported a fourth-quarter loss as it wrote down the value of its assets by $896 million due to weak gas prices. Shares dipped 1.6 percent to $59.60.

OfficeMax Inc and Office Depot Inc shares were halted as the companies announced a merger agreement. An earlier online statement of the deal was pulled down as an agreement had not yet been struck.

Toll Brothers Inc lost 4 percent to $35.43 after the largest luxury homebuilder in the United States, reported first-quarter results well below analysts' estimates.

SodaStream dropped 3.2 percent to $50.79 after the seller of home carbonated drink maker machines posted fourth-quarter earnings and provided a 2013 outlook.

According to Thomson Reuters data through Tuesday morning, of the 391 companies in the S&P 500 that have reported results, 70.1 percent have exceeded analysts' expectations, compared with a 62 percent average since 1994 and 65 percent over the past four quarters.

Fourth-quarter earnings for S&P 500 companies are estimated to have risen 5.6 percent, according to the data, above a 1.9 percent forecast at the start of the earnings season.

Venezuela's Maduro would win vote if Chavez goes: poll

CARACAS (Reuters) - Venezuelan Vice President Nicolas Maduro would win a presidential vote should his boss Hugo Chavez's cancer force him out, according to the first survey this year on such a scenario in the South American OPEC nation.

Local pollster Hinterlaces gave Maduro 50 percent of potential votes, compared to 36 percent for opposition leader Henrique Capriles.

Chavez made a surprise return to Venezuela on Monday, more than two months after cancer surgery in Cuba, to continue treatment at home for the disease that is jeopardizing his 14-year socialist rule.

He has named Maduro, 50, a former bus driver and union activist, as his preferred successor.

Capriles, 40, a center-left state governor who lost to Chavez in a presidential vote last year, likely would run again.

Chavez still has not spoken in public since his December 11 operation in Cuba. Venezuelans were debating on Tuesday the various possible scenarios after his homecoming - from full recovery to resignation or even death from the cancer.

There was widespread expectation Chavez would soon be formally sworn in for his new six-year term at the Caracas military hospital where officials said he was staying. The January 10 ceremony was postponed while he was in Cuba.

"The president's timeline is strictly linked to his medical evolution and recovery," said Rodrigo Cabezas, a senior member of Chavez's ruling Socialist Party who, like other officials, would not comment on when he might be sworn in.

CAPRILES ANGRY

Should Chavez be forced out, Venezuela's constitution stipulates an election must be held within 30 days, giving Capriles and the opposition Democratic Unity coalition another chance to end the socialists' lengthy grip on power.

Capriles, who crossed swords with Hinterlaces at various points during the presidential election, again accused its director, Oscar Schemel, of bias in the latest survey.

"That man is not a pollster, he's on the government's payroll," Capriles told local TV.

"He said in December I would lose the Miranda governorship," he added, referring to his defeat of government heavyweight Elias Jaua, now foreign minister, in that local race.

Opinion surveys are notoriously controversial and divergent in Venezuela, with both sides routinely accusing pollsters of being in the pocket of the other. But Hinterlaces successfully forecast Chavez's win with 55 percent of the vote in October.

Its latest poll was of 1,230 people between January 30-February 9.

Polls last year showed Capriles - an energetic basketball-playing lawyer who admires Brazil's centrist mix of free-market economics with strong social welfare policies - as more popular than any of Chavez's senior allies.

But Chavez's personal blessing of Maduro, on the eve of his last cancer surgery, has transformed his status and made him the heir apparent for many of the president's supporters.

As de facto leader since mid-December, Maduro also has built up a stronger public profile, copying the president's techniques of endless live TV appearances, especially to inaugurate new public works or promote popular policies like subsidized food.

He lacks Chavez's charisma, however, and opponents have slammed him as a "poor imitation" and incompetent.

EMOTION

Local analyst Luis Vicente Leon said that should Chavez die, Maduro would benefit from the emotion unleashed among his millions of passionate supporters in Venezuela.

"The funeral wake for Chavez would merge into the election campaign," he told a local newspaper, noting how Argentine President Cristina Fernandez's popularity surged when her husband and predecessor Nestor Kirchner died in 2010.

Maduro already has implemented an unpopular devaluation of the local currency and said more economic measures are coming this week in what local economists view as austerity measures after blowout spending prior to last year's election.

In Caracas, the streets were quieter after tumultuous celebrations of Chavez's homecoming by supporters on Monday. A few journalists stood outside the military hospital.

Prayer vigils were planned in various parts of Venezuela.

"We hope Chavez will stay governing because he is a strong man," supporter Cristina Salcedo, 50, said in Caracas.

Student demonstrators who had chained themselves near the Cuban Embassy last week, demanding more information on Chavez's condition, called off their protest after his return.

Until photos were published of him on Friday, the president had not been seen by the public since his six-hour December 11 operation, the fourth since cancer was detected in mid-2011.

The government has said Chavez is breathing through a tracheal tube and struggling to speak.

Bolivian President Evo Morales arrived in Caracas on Tuesday in the hope of visiting his friend and fellow leftist.

Michelle Obama: My Bangs Were a 'Midlife Crisis'

Taylor Hill/WireImage

When you’re the First Lady of the United States, you don’t have many options if you’re looking to act on a midlife crisis.

So Michelle Obama did what any woman looking to shake things up (within Secret Servce-approved parameters, of course) would do: cut her bangs.

“This is my midlife crisis, the bangs,” Obama joked on The Rachael Ray Show. “I couldn’t get a sports car. They won’t let me bungee-jump. So instead, I cut my bangs.”

And unlike many midlife crises, this one has gotten a big thumbs up from her spouse. “I love her bangs!” President Barack Obama said shortly after she cut them on her 49th birthday. “She always looks good.”

Not that she needed her husband’s approval, of course; though President Obama may be the leader of the free world, his wife is strictly the boss of her own hair. “I can do this,” she told Ray, smiling and gesturing to her new cut. “This is all mine.”

Tell us: Have you ever changed up your look impulsively? What do you think of Obama’s “midlife crisis”?

Hip implants a bit more likely to fail in women

CHICAGO (AP) — Hip replacements are slightly more likely to fail in women than in men, according to one of the largest studies of its kind in U.S. patients. The risk of the implants failing is low, but women were 29 percent more likely than men to need a repeat surgery within the first three years.

The message for women considering hip replacement surgery remains unclear. It's not known which models of hip implants perform best in women, even though women make up the majority of the more than 400,000 Americans who have full or partial hip replacements each year to ease the pain and loss of mobility caused by arthritis or injuries.

"This is the first step in what has to be a much longer-term research strategy to figure out why women have worse experiences," said Diana Zuckerman, president of the nonprofit National Research Center for Women & Families. "Research in this area could save billions of dollars" and prevent patients from experiencing the pain and inconvenience of surgeries to fix hip implants that go wrong.

Researchers looked at more than 35,000 surgeries at 46 hospitals in the Kaiser Permanente health system. The research, published Monday in JAMA Internal Medicine, was funded by the U.S. Food and Drug Administration.

After an average of three years, 2.3 percent of the women and 1.9 percent of the men had undergone revision surgery to fix a problem with the original hip replacement. Problems included instability, infection, broken bones and loosening.

"There is an increased risk of failure in women compared to men," said lead author Maria Inacio, an epidemiologist at Southern California Permanente Medical Group in San Diego. "This is still a very small number of failures."

Women tend to have smaller joints and bones than men, and so they tend to need smaller artificial hips. Devices with smaller femoral heads — the ball-shaped part of the ball-and-socket joint in an artificial hip — are more likely to dislocate and require a surgical repair.

That explained some, but not all, of the difference between women and men in the study. It's not clear what else may have contributed to the gap. Co-author Dr. Monti Khatod, an orthopedic surgeon in Los Angeles, speculated that one factor may be a greater loss of bone density in women.

The failure of metal-on-metal hips was almost twice as high for women than in men. The once-popular models were promoted by manufacturers as being more durable than standard plastic or ceramic joints, but several high-profile recalls have led to a decrease in their use in recent years.

"Don't be fooled by hype about a new hip product," said Zuckerman, who wrote an accompanying commentary in the medical journal. "I would not choose the latest, greatest hip implant if I were a woman patient. ... At least if it's been for sale for a few years, there's more evidence for how well it's working."
