Wall Street pauses after rally to five-year high

NEW YORK (Reuters) - Stocks drifted in light volume on Wednesday, ending little changed, as investors remained cautious after the S&P 500 index briefly hit its highest intraday level since November 2007.


The S&P 500 was buoyed by General Electric after cable company Comcast Corp said it will buy from GE the the part of NBCUniversal it didn't already own for $16.7 billion.


Comcast's stock hit the highest since 1999 before closing up 3 percent at $40.13 and GE gained 3.6 percent to $23.39.


The S&P 500 is up 6.6 percent so far this year, partly due to stronger-than-expected corporate earnings and a better economic outlook. The Dow industrials is about 1 percent away from an all-time intraday high, reached in October 2007.


Volume has been weak in recent days with the S&P moving sideways around 1,520. The index is about 3 percent away from closing at a record high.


A scarcity of sellers after a consistent string of gains is a positive sign and shows the uptrend is intact, King Lip, chief investment officer at Baker Avenue Asset Management in San Francisco, said.


"Last year we had double-digit returns in the first quarter. It's fairly possible we can move higher from here," he said.


The Dow Jones industrial average <.dji> fell 35.79 points or 0.26 percent, to 13,982.91, the S&P 500 <.spx> gained 0.9 point or 0.06 percent, to 1,520.33 and the Nasdaq Composite <.ixic> added 10.38 points or 0.33 percent, to 3,196.88.


The S&P gained 12 percent in the first three months of 2012.


Deere & Co , the world's largest farm equipment maker, forecast a modest increase in sales this year despite the prospect of the biggest corn crop in U.S. history. The forecast fell short of analysts' expectations, sending shares of Deere down 3.5 percent to $90.68.


In extended trading, shares of technology bellwether Cisco Systems fell 2 percent after it posted results.


Dr Pepper Snapple fell 5.8 percent to $42.69 after it forecast profit for the current year below analysts' estimates.


Cliffs Natural Resources lost a fifth of its market value a day after the miner reported a quarterly loss and slashed its dividend by 76 percent. Its shares fell 20 percent to 429.29.


According to the latest Thomson Reuters data, of the 364 companies in the S&P 500 that have reported results, 70.3 percent have exceeded analysts' expectations, above a 62 percent average since 1994 and 65 percent over the past four quarters.


About 5.9 billion shares changed hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below the daily average in February last year of 6.94 billion.


On the NYSE, roughly seven issues rose for every five that fell and on Nasdaq more than six rose for every five decliners.

South Korea unveils missile it says can hit North's leaders


SEOUL (Reuters) - South Korea unveiled a cruise missile on Thursday that it said can hit the office of North Korea's leaders, trying to address concerns that it is technologically behind its unpredictable rival which this week conducted its third nuclear test.


South Korean officials declined to say the exact range of the missile but said it could hit targets anywhere in North Korea.


The Defence Ministry released video footage of the missiles being launched from destroyers and submarines striking mock targets. The weapon was previewed in April last year and officials said deployment was now complete.


"The cruise missile being unveiled today is a precision-guided weapon that can identify and strike the window of the office of North Korea's leadership," ministry spokesman Kim Min-seok said told reporters.


North Korea has forged ahead with long-range missile development, successfully launching a rocket in December that put a satellite into orbit.


The North's ultimate aim, Washington believes, is to design an intercontinental ballistic missile capable of carrying a nuclear warhead that could hit the United States.


North Korea, which accuses the United States and its "puppet", South Korea, of war-mongering on an almost daily basis, is likely to respond angrily to South Korea flexing its muscles.


North Korea, technically still at war with the South after their 1950-53 conflict ended in a truce, not a peace treaty, carried out its third nuclear test on Tuesday, drawing condemnation from around the world including its only major ally China.


The test and the threat of more unspecified actions from Pyongyang have raised tensions on the Korean peninsula as the South prepares to inaugurate a new president on February 25.


"The situation prevailing on the Korean peninsula at present is so serious that even a slight accidental case may lead to an all-out war which can disturb the whole region," North Korea's official KCNA news agency said.

Larry Bird's Son Connor Arrested















02/12/2013 at 10:00 PM EST







Conner Bird


Monroe County Sheriff’s Office/AP


Basketball star Larry Bird's son is in trouble with the law.

According to CBS Chicago, 21-year-old Connor Bird was involved in an argument with an ex-girlfriend at his apartment on Sunday afternoon and reportedly threw a cell phone at her.

Hours later, the two drove to a nearby parking lot where the woman got out of the car, intending to walk home, and Conner allegedly attempted to hit her twice with his vehicle.

Bird was later arrested by the Indiana University Police on charges of battery with injury, criminal mischief, intimidation with a deadly weapon and possession of marijuana. He is now free on bail. No trial date has been set.

A lawyer for Bird tells PEOPLE: "What has happened is a very private matter. We’re trying to resolve this as quickly as possible and we're all thankful no one was seriously injured."

Bird was reportedly arrested in 2011 for underage drinking and disorderly conduct, according to TMZ.

Study questions kidney cancer treatment in elderly


In a stunning example of when treatment might be worse than the disease, a large review of Medicare records finds that older people with small kidney tumors were much less likely to die over the next five years if doctors monitored them instead of operating right away.


Even though nearly all of these tumors turned out to be cancer, they rarely proved fatal. And surgery roughly doubled patients' risk of developing heart problems or dying of other causes, doctors found.


After five years, 24 percent of those who had surgery had died, compared to only 13 percent of those who chose monitoring. Just 3 percent of people in each group died of kidney cancer.


The study only involved people 66 and older, but half of all kidney cancers occur in this age group. Younger people with longer life expectancies should still be offered surgery, doctors stressed.


The study also was observational — not an experiment where some people were given surgery and others were monitored, so it cannot prove which approach is best. Yet it offers a real-world look at how more than 7,000 Medicare patients with kidney tumors fared. Surgery is the standard treatment now.


"I think it should change care" and that older patients should be told "that they don't necessarily need to have the kidney tumor removed," said Dr. William Huang of New York University Langone Medical Center. "If the treatment doesn't improve cancer outcomes, then we should consider leaving them alone."


He led the study and will give results at a medical meeting in Orlando, Fla., later this week. The research was discussed Tuesday in a telephone news conference sponsored by the American Society of Clinical Oncology and two other cancer groups.


In the United States, about 65,000 new cases of kidney cancer and 13,700 deaths from the disease are expected this year. Two-thirds of cases are diagnosed at the local stage, when five-year survival is more than 90 percent.


However, most kidney tumors these days are found not because they cause symptoms, but are spotted by accident when people are having an X-ray or other imaging test for something else, like back trouble or chest pain.


Cancer experts increasingly question the need to treat certain slow-growing cancers that are not causing symptoms — prostate cancer in particular. Researchers wanted to know how life-threatening small kidney tumors were, especially in older people most likely to suffer complications from surgery.


They used federal cancer registries and Medicare records from 2000 to 2007 to find 8,317 people 66 and older with kidney tumors less than 1.5 inches wide.


Cancer was confirmed in 7,148 of them. About three-quarters of them had surgery and the rest chose to be monitored with periodic imaging tests.


After five years, 1,536 had died, including 191 of kidney cancer. For every 100 patients who chose monitoring, 11 more were alive at the five-year mark compared to the surgery group. Only 6 percent of those who chose monitoring eventually had surgery.


Furthermore, 27 percent of the surgery group but only 13 percent of the monitoring group developed a cardiovascular problem such as a heart attack, heart disease or stroke. These problems were more likely if doctors removed the entire kidney instead of just a part of it.


The results may help doctors persuade more patients to give monitoring a chance, said a cancer specialist with no role in the research, Dr. Bruce Roth of Washington University in St. Louis.


Some patients with any abnormality "can't sleep at night until something's done about it," he said. Doctors need to say, "We're not sticking our head in the sand, we're going to follow this" and can operate if it gets worse.


One of Huang's patients — 81-year-old Rhona Landorf, who lives in New York City — needed little persuasion.


"I was very happy not to have to be operated on," she said. "He said it's very slow growing and that having an operation would be worse for me than the cancer."


Landorf said her father had been a doctor, and she trusts her doctors' advice. Does she think about her tumor? "Not at all," she said.

Comcast to buy rest of NBC stake for $16.7 billion


(Reuters) - Comcast Corp on Tuesday said it would buy General Electric's remaining 49 percent equity stake in their NBCUniversal joint venture for about $16.7 billion, speeding up a deal that had not been expected until at least late 2014.


Analysts said Comcast was getting a good deal at that price, while Comcast's chief executive said the company moved because it was eager to take control of the business sooner than planned.


Comcast shares rose 7.5 percent in afterhours trading.


Comcast bought 51 percent of NBC Universal in 2011 after winning antitrust approval from the Justice Department. The transaction created a $30 billion business that includes broadcast, cable networks, movie studios and theme parks.


"Pretty much in our opinion given that media stocks have gone up quite a bit, it's a very attractive price, a fair price because we had a formula buyout," Comcast Chairman and Chief Executive Brian Roberts said in an interview with Reuters. "We feel many good things coming today and in the future and we wanted to get 100 percent of that for our shareholders."


In addition to the main deal, NBCUniversal will also buy from GE Capital the properties it uses at 30 Rockefeller Plaza in New York City and CNBC's headquarters in Englewood Cliffs, New Jersey, for about $1.4 billion.


Comcast said it would fund the deal with $11.4 billion of cash on hand, $4 billion in senior unsecured notes to be issued to GE, $2 billion in credit facility borrowings and the issuance of $725 million in subsidiary preferred stock to GE.


Separately, Comcast said it would increase its dividend by 20 percent and that it would buy back $2 billion in stock this year. GE also said it would accelerate its own share buy-back program to $10 billion this year.


"It's an attractive price - Comcast is getting a good deal," Wunderlich Securities analyst Matthew Harrigan said.


LONG-HELD AMBITIONS


Comcast turned its attention to NBC after a failed $54 billion hostile takeover attempt of Disney in 2004 that ultimately led to the resignation of that company's CEO, Michael Eisner, after more than 20 years on the job.


The hostile offer exposed Comcast's desire to merge content with distribution at a time when most of its industry peers, such as Viacom-CBS and AOL-Time Warner, were doing the opposite.


While Comcast held the title of the nation's leading cable operator by a wide margin, its status as a content player was always second tier, with middling networks like E!, G4 and Golf forming the basis of its channel portfolio.


The NBC deal gave the Philadelphia-based cable operator the cable industry's top-rated entertainment network, USA, its leading business network CNBC, upstart news network MSNBC and Bravo, among others.


For GE, the sale culminates a long-planned exit from the entertainment business.


Since reaching the deal to sell its majority stake in NBC Universal, GE officials have made clear that they eventually planned to exit the entertainment business entirely.


The initial sale contract gave GE the option to sell back as much as all its remaining stake in NBC Universal by mid-2014.


The company's accelerated share buyback could be an answer to shareholders, who have wondered what GE would do with a cash windfall that could total tens of billions of dollars over several years, as the company sold its remaining NBC stake and recouped more profits earned by GE Capital.


COMCAST EARNINGS


In addition to the GE deal, Comcast reported fourth-quarter earnings on Tuesday.


It posted $15.94 billion in revenue, up 6 percent from a year ago. It posted net income of $1.8 billion, or 56 cents per share, up from $1.56 billion, or 47 cents a year ago.


In its cable business, it lost a net 7,000 video customers, which is better than the 17,000 subscribers lost a year ago.


Wall Street analysts were expecting Comcast to lose 5,000 customers, according to StreetAccount. It added 341,000 Internet customers in the quarter, which beat the 329,000 new customers analysts were expecting.


Comcast shares rose to $41.89 after the market close from $38.97 in regular trading. GE shares rose 3 percent to $23.37 from a $22.58 close.

North Korean nuclear test draws anger, including from China


SEOUL (Reuters) - North Korea conducted its third nuclear test on Tuesday in defiance of U.N. resolutions, drawing condemnation from around the world, including from its only major ally, China, which summoned the North Korean ambassador to protest.


Pyongyang said the test was an act of self-defense against "U.S. hostility" and threatened stronger steps if necessary.


The test puts pressure on U.S. President Barack Obama on the day of his State of the Union speech and also puts China in a tight spot, since it comes in defiance of Beijing's admonishments to North Korea to avoid escalating tensions.


The U.N. Security Council held an emergency meeting at which its members, including China, "strongly condemned" the test and vowed to start work on appropriate measures in response, the president of the council said.


North Korean leader Kim Jong-un, the third of his line to rule the country, has presided over two long-range rocket launches and a nuclear test during his first year in power, pursuing policies that have propelled his impoverished and malnourished country closer to becoming a nuclear weapons power.


North Korea said the test had "greater explosive force" than those it conducted in 2006 and 2009. Its KCNA news agency said it had used a "miniaturized" and lighter nuclear device, indicating it had again used plutonium, which is suitable for use as a missile warhead.


China, which has shown signs of increasing exasperation with the recent bellicose tone of its reclusive neighbor, summoned the North Korean ambassador in Beijing and protested sternly, the Foreign Ministry said.


Foreign Minister Yang Jiechi said China was "strongly dissatisfied and resolutely opposed" to the test and urged North Korea to "stop any rhetoric or acts that could worsen situations and return to the right course of dialogue and consultation as soon as possible".


Analysts said the test was a major embarrassment to China, which is a permanent member of the Security Council and North Korea's sole major economic and diplomatic ally.


Obama called the test a "highly provocative act" that hurt regional stability.


"The danger posed by North Korea's threatening activities warrants further swift and credible action by the international community. The United States will also continue to take steps necessary to defend ourselves and our allies," Obama said.


U.S. Ambassador to the United Nations Susan Rice said Washington and its allies intended to "augment the sanctions regime" already in place due to Pyongyang's previous atomic tests. North Korea is already one of the most heavily sanctioned states in the world and has few external economic links that can be targeted.


Japanese Prime Minister Shinzo Abe said the test was a "grave threat" that could not be tolerated.


Russian Foreign Minister Sergei Lavrov urged North Korea to abandon its nuclear arms program and return to talks. NATO condemned the test as an "irresponsible act."


South Korea, still technically at war with North Korea after a 1950-53 civil war ended in a mere truce, also denounced the test. Obama spoke to South Korean President Lee Myung-bak on Tuesday and told him the United States "remains steadfast in its defense commitments" to Korea, the White House said.


MAXIMUM RESTRAINT


North Korea's Foreign Ministry said the test was "only the first response we took with maximum restraint".


"If the United States continues to come out with hostility and complicates the situation, we will be forced to take stronger, second and third responses in consecutive steps," it said in a statement carried by the official KCNA news agency.


North Korea - which gave the U.S. State Department advance warning of the test - often threatens the United States and its "puppet", South Korea, with destruction in colorful terms.


North Korea told the U.N. disarmament forum in Geneva that it would never bow to resolutions on its nuclear program and that prospects were "gloomy" for the denuclearization of the divided Korean peninsula because of a "hostile" U.S. policy.


Suzanne DiMaggio, an analyst at the Asia Society in New York, said North Korea had embarrassed China with the test. "China's inability to dissuade North Korea from carrying through with this third nuclear test reveals Beijing's limited influence over Pyongyang's actions in unusually stark terms," she said.


Mark Fitzpatrick of the International Institute for Strategic Studies think tank, said: "The test is hugely insulting to China, which now can be expected to follow through with threats to impose sanctions."


The magnitude of the explosion was roughly twice that of the 2009 test, according to the Vienna-based Comprehensive Nuclear-Test Ban Treaty Organization. The U.S. Geological Survey said that a seismic event measuring 5.1 magnitude had occurred.


U.S. intelligence agencies were analyzing the event and found that North Korea probably conducted an underground nuclear explosion with a yield of "approximately several kilotons", the Office of the Director of National Intelligence said.


Nuclear experts have described Pyongyang's previous two tests as puny by international standards. The yield of the 2006 test has been estimated at less than 1 kiloton (1,000 tons of TNT equivalent) and the second at some 2-7 kilotons, compared with 20 kilotons for a Nagasaki-type bomb.


Initial indications are that the test involved the latest version of a plutonium-based prototype weapon, according to one current and one former U.S. national security official. Both previous tests involved plutonium. If it turns out the test was of a new uranium-based weapon, it would show that North Korea has made more progress on uranium enrichment than previously thought.


The United States uses WC-135 Constant Phoenix "sniffer" aircraft to collect samples to identify nuclear explosions. These would need to be deployed quickly to detect whether highly enriched uranium rather than plutonium was used because uranium decays to undetectable levels within a matter of days. Plutonium takes much longer to decay.


North Korea trumpeted news of the test on its state television channel to patriotic music against a backdrop of its national flag.


"It was confirmed that the nuclear test that was carried out at a high level in a safe and perfect manner using a miniaturized and lighter nuclear device with greater explosive force than previously did not pose any negative impact on the surrounding ecological environment," KCNA said.


North Korea linked the test to its technical prowess in launching a long-range rocket in December, a move that triggered the U.N. sanctions, backed by China, that Pyongyang said prompted it to take Tuesday's action.


The North's ultimate aim, Washington believes, is to design an intercontinental ballistic missile capable of carrying a nuclear warhead that could hit the United States. North Korea says the program is aimed at putting satellites in space.


Despite its three nuclear tests and long-range rocket tests, North Korea is not believed to be close to manufacturing a nuclear missile capable of hitting the United States.


It used plutonium in previous nuclear tests and before Tuesday there had been speculation that it would use highly enriched uranium so as to conserve its plutonium stocks, as testing eats into its limited supply of materials to construct a nuclear bomb.


"VICIOUS CYCLE"


When Kim Jong-un, who is 30, took power after his father's death in December 2011, there were hopes that he would bring reforms and end Kim Jong-il's "military first" policies.


Instead, North Korea, whose economy is smaller than it was 20 years ago and where a third of children are believed to be malnourished, appears to be trapped in a cycle of sanctions followed by further provocations.


"The more North Korea shoots missiles, launches satellites or conducts nuclear tests, the more the U.N. Security Council will impose new and more severe sanctions," said Shen Dingli, a professor at Shanghai's Fudan University. "It is an endless, vicious cycle."


Options for the international community appear to be in short supply. Diplomats at the United Nations said negotiations on new sanctions could take weeks since China is likely to resist tough new measures for fear they could lead to further retaliation by the North Korean leadership.


Beijing has also been concerned that tougher sanctions could further weaken North Korea's economy and prompt a flood of refugees into China.


Tuesday's action appeared to have been timed for the run-up to February 16 anniversary celebrations of Kim Jong-il's birthday, as well as to achieve maximum international attention.


Significantly, the test comes at a time of political transition in China, Japan and South Korea, and as Obama begins his second term. The U.S. president will likely have to tweak his State of the Union address due to be given on Tuesday.


Japanese Prime Minister Shinzo Abe is bedding down a new government and South Korea's new president, Park Geun-hye, is preparing to take office on February 25.


China too is in the midst of a once-in-a-decade leadership transition to Xi Jinping, who takes office in March. Both Abe and Xi are staunch nationalists.


The longer-term game plan from Pyongyang may be to restart international talks aimed at winning food and financial aid. China urged it to return to the stalled "six-party" talks on its nuclear program, hosted by China and including the two Koreas, the United States, Japan and Russia.


Its puny economy and small diplomatic reach mean that North Korea struggles to win attention on the global stage - other than through nuclear tests and attacks on South Korea, the last of which was made in 2010.


"Now the next step for North Korea will be to offer talks... - any form to start up discussion again to bring things to their advantage," predicted Jeung Young-tae, senior research fellow at the Korea Institute for National Unification in Seoul.

Google may be paying Apple $1 billion a year to be the default search engine in iOS






Google (GOOG) could be paying Apple (AAPL) as much as $ 1 billion a year for the right to the be default search engine on iPhones, iPads and the iPod touch. Scott Devitt of Morgan Stanley praised Google in a recent note to investors, Business Insider reported. The analyst said, “the next Google is Google,” noting that the company is continuing to prove itself in an ever-changing market. He believes that Google’s search business has more room to grow in expanding markets and subsidiaries such as YouTube could generate as much as $ 20 billion by 2020.


[More from BGR: Four Android smartphones lead the iPhone 5 in customer satisfaction ratings]






Devitt estimated within the note that Google could be paying Apple up to $ 1 billion just to be the default search engine in iOS, and that figure is expected to increase over the next few years. Earlier reports claimed the two companies were involved in a revenue sharing deal, however the analyst doesn’t think this is the case because it would be too messy.


[More from BGR: Next-gen Xbox may feature advanced multitasking and require Kinect to function]


He thinks Apple would instead be far more likely to do a fee per device agreement for the benefits of upfront payments and easier accounting. The analyst believes this unlikely partnership has helped Google control an estimated 95% of the mobile search market.


As Jay Yarow of Business Insider wrote, “when you consider that Apple and Android are swallowing the mobile market, paying ~$ 1 billion a year for a monopoly on the most lucrative online business in the world is a no-brainer.”

Pope shows lifetime jobs aren't always for life


The world seems surprised that an 85-year-old globe-trotting pope who just started tweeting wants to resign, but should it be? Maybe what should be surprising is that more leaders his age do not, considering the toll aging takes on bodies and minds amid a culture of constant communication and change.


There may be more behind the story of why Pope Benedict XVI decided to leave a job normally held for life. But the pontiff made it about age. He said the job called for "both strength of mind and body" and said his was deteriorating. He spoke of "today's world, subject to so many rapid changes," implying a difficulty keeping up despite his recent debut on Twitter.


"This seemed to me a very brave, courageous decision," especially because older people often don't recognize their own decline, said Dr. Seth Landefeld, an expert on aging and chairman of medicine at the University of Alabama at Birmingham.


Age has driven many leaders from jobs that used to be for life — Supreme Court justices, monarchs and other heads of state. As lifetimes expand, the woes of old age are catching up with more in seats of power. Some are choosing to step down rather than suffer long declines and disabilities as the pope's last predecessor did.


Since 1955, only one U.S. Supreme Court justice — Chief Justice William Rehnquist — has died in office. Twenty-one others chose to retire, the most recent being John Paul Stevens, who stepped down in 2010 at age 90.


When Thurgood Marshall stepped down in 1991 at the age of 82, citing health reasons, the Supreme Court justice's answer was blunt: "What's wrong with me? I'm old. I'm getting old and falling apart."


One in 5 U.S. senators is 70 or older, and some have retired rather than seek new terms, such as Hawaii's Daniel Akaka, who left office in January at age 88.


The Netherlands' Queen Beatrix, who just turned 75, recently said she will pass the crown to a son and put the country "in the hands of a new generation."


In Germany, where the pope was born, Chancellor Angela Merkel, who is 58, said the pope's decision that he was no longer fit for the job "earns my very highest respect."


"In our time of ever-lengthening life, many people will be able to understand how the pope as well has to deal with the burdens of aging," she told reporters in Berlin.


Experts on aging agreed.


"People's mental capacities in their 80s and 90s aren't what they were in their 40s and 50s. Their short-term memory is often not as good, their ability to think quickly on their feet, to execute decisions is often not as good," Landefeld said. Change is tougher to handle with age, and leaders like popes and presidents face "extraordinary demands that would tax anybody's physical and mental stamina."


Dr. Barbara Messinger-Rapport, geriatrics chief at the Cleveland Clinic, noted that half of people 85 and older in developed countries have some dementia, usually Alzheimer's. Even without such a disease, "it takes longer to make decisions, it takes longer to learn new things," she said.


But that's far from universal, said Dr. Thomas Perls, an expert on aging at Boston University and director of the New England Centenarians Study.


"Usually a man who is entirely healthy in his early 80s has demonstrated his survival prowess" and can live much longer, he said. People of privilege have better odds because they have access to good food and health care, and tend to lead clean lives.


"Even in the 1500s and 1600s there were popes in their 80s. It's remarkable. That would be today's centenarians," Perls said.


Arizona Sen. John McCain turned 71 while running for president in 2007. Had he won, he would have been the oldest person elected to a first term as president. Ronald Reagan was days away from turning 70 when he started his first term as president in 1981; he won re-election in 1984. Vice President Joe Biden just turned 70.


In the U.S. Senate, where seniority is rewarded and revered, South Carolina's Strom Thurmond didn't retire until age 100 in 2002. Sen. Robert Byrd of West Virginia was the longest-serving senator when he died in office at 92 in 2010.


Now the oldest U.S. senator is 89-year-old Frank Lautenberg of New Jersey. The oldest congressman is Ralph Hall of Texas who turns 90 in May.


The legendary Alan Greenspan was about to turn 80 when he retired as chairman of the Federal Reserve in 2006; he still works as a consultant.


Elsewhere around the world, Cuba's Fidel Castro — one of the world's longest serving heads of state — stepped down in 2006 at age 79 due to an intestinal illness that nearly killed him, handing power to his younger brother Raul. But the island is an example of aged leaders pushing on well into their dotage. Raul Castro now is 81 and his two top lieutenants are also octogenarians. Later this month, he is expected to be named to a new, five-year term as president.


Other leaders who are still working:


—England's Queen Elizabeth, 86.


—Abdullah bin Abd al-Aziz al-Saud, king of Saudi Arabia, 88.


—Sabah al-Ahmad al-Jaber al-Sabah, emir of Kuwait, 83.


—Ruth Bader Ginsburg, U.S. Supreme Court associate justice, 79.
