Video games take off as a spectator sport

Editorial: "Give video games a sporting chance"

EVERY sport has its idols and superstars. Now video gaming is getting them too. Professional gaming, or e-sports, exploded in popularity in the US and Europe last year.

The scene has been big in Asia - particularly South Korea - for about a decade, with top players such as Lim Yo-Hwan earning six-figure salaries and competing for rock-star glory in Starcraft tournaments that attract audiences in the hundreds of thousands.

The phenomenon is taking off in the West partly because of improved video-streaming technology and large financial rewards. Video games are becoming a spectator sport, with certain players and commentators drawing massive online audiences.

And where people go, money follows. The second world championship of League of Legends - a team-based game in which players defend respective corners of a fantasy-themed battle arena - was held in Los Angeles in October. The tournament had a prize pool of $5 million for the season, with $1 million going to winning team Taipei Assassins, the largest cash prize in the history of e-sports.

League of Legends has also set records for spectator numbers. More than 8 million people watched the championship finals either online or on TV - a figure that dwarfs audience numbers for broadcasts of many traditional sports fixtures.

But gamers don't need to compete at the international level to earn money. Video-streaming software like Twitch makes it easy for players to send live footage to a website, where the more popular ones can attract upwards of 10,000 viewers - enough for some to make a living by having adverts in their video streams. Gamers can go pro without leaving their homes.

Currently, e-sports productions are handled by gaming leagues - but that could soon change. Last November saw two moves that will make it even easier to reach a global online audience. First, Twitch announced it would be integrating with Electronic Arts's Origin service, a widely used gaming platform. This would let gamers stream their play at the click of a button, making it easy for people around the world to watch.

Also in November came the latest release from one of gaming's biggest franchises, Call of Duty: Black Ops 2, which has the ability to live-stream via YouTube built into the game itself. Another feature allows the broadcast of in-game commentary for multiplayer matches.

"I think we will reach a point, maybe within five years, where spectator features are a necessity for all big game releases," says Corin Cole of e-sports publishing company Heaven Media in Huntingdon, UK.

David Ting founded the California-based IGN Pro League (IPL), which hosts professional tournaments. He puts the popularity of e-sports down to the demand for new forms of online entertainment. "After 18 months, IPL's viewer numbers are already comparable to college sports in the US when there's a live event," he says. "The traffic is doubling every six months."

Ting sees motion detection, virtual reality and mobile gaming coming together to make physical exertion a more common aspect of video games, blurring the line between traditional sport and e-sports. "Angry Birds could be this century's bowling," says Ting.

Chavez not in coma, responding well to treatment: brother

CARACAS Ailing Venezuelan President Hugo Chavez is not in a coma and is responding well to cancer treatment in Cuba, making daily progress, his brother said Saturday.

"Reports that the president is in a coma and that the family is discussing ending life support, are totally false," Adan Chavez, governor of the state of Barinas, said in a statement.

He "continues to respond well to his medical care and to make daily progress in his recovery."

Chavez has been out of public sight since undergoing surgery in Havana on December 11, the fourth such operation in the 18 months since his condition was made public.

Officials have said the fiery leftist leader is suffering from a severe pulmonary infection that has resulted in a "respiratory insufficiency," fueling speculation about his prospects for a full recovery -- and his political future.

The uncertainty surrounding Chavez's condition has rattled Venezuela, the nation with the world's largest proven oil reserves.

The government was forced to postpone the president's scheduled inauguration Thursday, as it became clear that he could not attend. Authorities insist the country's constitution allows Chavez to take the oath of office later on.

But the opposition has cried foul, calling for a medical board to review the absent leader's health -- a demand rejected by the Supreme Court, which said the delayed swearing-in was constitutional.

In Cuba on Saturday, President Raul Castro voiced his support for the Venezuelan leadership, his government's closest and most critical economic and political ally.

Castro made the comments during a meeting with Venezuelan Vice President Nicolas Maduro, who arrived in the Cuban capital late Friday to check on his ailing boss, who had a difficult fourth round of cancer surgery last month.

Raul Castro "expressed his confidence in the ability of the Venezuelan people and their institutions to address and overcome any challenge," a government statement said.

"Raul and Maduro shared their mutual satisfaction with the emotional demonstration of support for Venezuela and President Chavez on January 10 in Caracas," it added.

Two Chavez allies, Argentine President Cristina Kirchner and Peruvian President Ollanta Humala, also arrived in Havana on Friday.

"We all hope for a quick recovery," Humala said.

Kirchner refused to comment on Chavez's health when asked by reporters, saying it should be left to his family. She did, however, thank retired revolutionary icon Fidel Castro, 86, for hosting a luncheon for her in his home Friday.

Like Chavez, Castro has been sidelined by health problems and rarely appears in public since stepping aside as president of the communist country in 2006.

Throughout his illness, first detected in June 2011, Chavez -- in power for 14 years -- has refused to relinquish the powers of the presidency, even when leaving for Cuba for his latest surgery.

The Venezuelan constitution says new elections must be held within 30 days if the president-elect or president dies or is permanently incapacitated, either before he takes office or in the first four years of his six-year term.

Making job stress worth enduring

Defense Secretary Leon Panetta swears in reenlisting troops in Turkey. A survey found that military jobs tend to be the most stressful.

STORY HIGHLIGHTS

• Marci Alboher: Annual list of most stressful jobs drew attention


• She says the right issue is whether job rewards compensate for stress


• People who take on stressful jobs that help others report satisfaction, she says

Editor's note: Marci Alboher, is a Vice President of Encore.org, a nonprofit making it easier for people to pursue second acts for the greater good. Her latest book is, "The Encore Career Handbook: How to Make a Difference and a Living in the Second Half of Life" (Workman: January 2013).

(CNN) -- A recent study with a catchy headline about the most stressful jobs of 2013 found its way to the soft hour of news this week.

The annual study by careercast.com created some buzz in the online water cooler and I was asked to appear on the "Today" show to talk about it. Colleagues e-mailed me and posted on my Facebook page about where their chosen professions ranked. My media friends couldn't help noticing that public relations professionals, reporters and photojournalists all made it into the top 10 for stress.

The "study," referred to in quotes in some of the commentary, considered some logical criteria to come up with these rankings. Proximity to risk of death (yours or others'), travel, deadlines, working in the public eye and physical demands all racked up points on the stress scale. And there's no arguing that military personnel, firefighters and police officers -- all high-rankers on the most-stressed list -- are exposed to higher stakes than your typical seamstress (holder of the second-least stressful job slot).

Marci Alboher

The job that snagged the "least stressful" slot, according to the survey, was "university professor," a designation that caused outrage among people who actually hold that job. One commenter conceded that most academic jobs don't put you in personal danger (though you can argue that point), but anyone who's ever been around professors knows that faculty politics, difficult students and pressure to "publish or perish" can cause even the most calm character to crack.

We could debate whether these designations make any sense. And whether every police officer, firefighter and member of the military faces the same amount of stress.

But let's make sure we are having the right conversation. How many people choose a profession based on how high the stress level is? And how can you measure stress objectively? If you're prone to stress, perhaps you're just as likely to feel stressed out whether you work as a librarian, a massage therapist or a commercial airline pilot (No. 4 on the stress list).

People choose their line of work for a lot of reasons. For those who are committed to making our communities and the world safer and healthier for the rest of us, minimizing stress is probably not so high on their list of criteria. And it shouldn't be. Folks who choose helping jobs that may have a high level of stress are fueled by other motivators, like wanting their work to have meaning.

They aren't deterred by the fact that their job will likely come with stress. And some people are simply by their own nature and personalities drawn to work that may be to others, dauntingly stressful. How many FBI agents do you think would prefer a gig as an audiologist (sixth-least stressful job)?

When I talk to men and women in their 50s and 60s who've decided to take on encore careers as teachers, they tell me that the work is often exhausting and stressful. They are on their feet all day, often with inadequate resources, with kids who are themselves highly stressed; even those who come from leadership roles in other sectors say they've never worked harder. Yet they almost always tell me that doing something that matters to others -- and that puts them in touch with young people every day -- compensates for the added stress.

The same is true of those tackling some of the world's most intractable problems. When I talk to Stephen and Elizabeth Alderman, whose foundation trains health-care professionals around the world to work with victims of trauma, or Judith Broder, who founded The Soldiers Project, which works with returning veterans, they rarely talk about stress. Instead they talk about how they are compelled to do what they do, because moving the needle even a fraction is better than doing nothing.

Rather than discouraging people to take on jobs that might have a lot of stress, let's instead encourage those who are designed for those jobs to do them. And let's make sure to support our friends and family members who go down these paths.

It's hard to grab headlines in the crowded space of morning television, but a good survey with a catchy title will always do that. So let's use these kinds of surveys to have the right kinds of conversations. Like why so many jobs that keep us safe and healthy, and that care for our children and the environment rarely show up on lists of the most highly compensated jobs. Now there's a conversation I'd most like to be having.

Treasury: No $1 trillion coin

A Treasury Department spokesman announced today that the department will not mint a platinum coin to sidestep raising the federal government's borrowing limit, telling the Washington Post that "neither the Treasury Department nor the Federal Reserve believes that the law can or should be used to facilitate the production of platinum coins for the purpose of avoiding an increase in the debt limit."

The idea, which had gained traction among some congressional Democrats and political analysts as a way of defanging the debt ceiling as a bargaining chip, was that the Treasury Department could simply mint a platinum coin, declare the value at $1 trillion, and deposit it into the Federal Reserve to allow continued spending in the absence of a vote to raise the debt ceiling.

With the idea now buried by Treasury, the stage is set for a full-on fight about the debt ceiling. President Obama and congressional Democrats have signaled that they simply will not negotiate on a vote to raise the borrowing limit, saying that it is Congress's duty to pay bills it has already accrued.

But congressional Republicans have given every indication that they plan to use the debt limit as a bargaining chip to extract deep spending cuts from reluctant Democrats.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Lottery Winner Murdered: Widow Questioned By Police Watch Video

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

US mulls aid to French in Mali, including drones

WASHINGTON: The US military is weighing support for French forces in Mali including surveillance drones, a US official said Friday, as Washington backed moves to deny safe haven to extremists in the country.

US commanders were looking at providing intelligence and aerial refueling tankers among a range of options, such as logistical backup and boosting intelligence sharing, which would involve surveillance drones, the official, who spoke on condition of anonymity, told AFP.

Backed by French air power, Mali on Friday unleashed an offensive against Islamist rebels who have seized control of the north of the West African country and are now threatening to push south.

Senior US officials held talks with their counterparts in the French capital and other allies on drawing up an action plan, the official said.

President Francois Hollande confirmed in Paris that French forces were supporting an attack aimed at repelling the Al-Qaeda-linked radicals who have triggered international alarm with moves towards the capital Bamako.

The United States said Friday it shared France's goal of denying the extremists safe haven in Mali.

"We are monitoring the situation closely," National Security Council spokesman Tommy Vietor told AFP.

"We have noted that the government of Mali has asked for support, and we share the French goal of denying terrorists a safe haven in the region."

Hollande gave no indication of the scale of French involvement, but said it would last "for as long as is necessary."

The American military has a network of air bases in Italy, Spain and elsewhere in the region that could provide refueling tankers and other assistance to the French.

Former colonial power France has warned that the Islamist rebels were seeking to transform the vast nation into a "terrorist state."

State Department spokesman Victoria Nuland meanwhile said Washington was "consulting very closely" with the French government on the fighting.

"Obviously we remain deeply concerned by the recent events in Mali. We echo the international community's condemnation of these recent aggressive acts."

Earlier Friday, French Defense Minister Jean-Yves Le Drian briefed his US counterpart Leon Panetta about the situation.

Why death comes sooner in America

A report finds that Americans have "shorter lives and poorer health," coming in last in key areas behind 16 other rich nations

STORY HIGHLIGHTS

• Aaron Carroll: New study shows U.S. health and lifespan worst of 17 rich countries


• He says it's because of personal choices, systemic woes. Poverty high, health care uneven


• He says this particularly affects youth, plagued by sickness, violence, high mortality


• Carroll: Don't make it political. The richest country in the world must improve public health

Editor's note: Dr. Aaron E. Carroll is an associate professor of pediatrics at the Indiana University School of Medicine and the director of the university's Center for Health Policy and Professionalism Research. He blogs about health policy at The Incidental Economist and tweets at @aaronecarroll.

(CNN) -- A just-released report from the Institute of Medicine and National Research Council is making news by clearly illustrating that Americans have "shorter lives and poorer health." This is somewhat shocking, given how much we spend on health care each year — more than any of the 16 other rich countries surveyed in the study. What's even more upsetting is that this report focused quite heavily on people who are young. In the United States, even that group fared poorly.

Aaron Carroll

Why is this?

Some of the reasons involve choices make at a personal level. We eat too much, abuse drugs too often, wear seat belts too rarely and commit violence against each other to often.

Systemic issues are also to blame. We have higher levels of poverty than comparable countries, and our safety net programs are less capable of catching people when they fall. And too many also have too much trouble accessing the health care system, resulting in inefficient, ineffective and often absent care.

It's far too easy to let these dreadful statistics become obscured in a politically charged argument. Let's avoid that. This report is so stark that it's going to take a concerted effort on the part of the government, the media, the health care system and everyday citizens to turn things around. Our personal choices are bad. Our safety nets are bad. Our health care system is bad. It's all bad. How bad?

When compared with peer countries, the United States was the absolute worst with respect to still births, infant mortality and low birth weight. Some have tried to blame this on "coding" differences. In other words, they will claim that other countries will refuse to define a premature birth as we do, resulting in artificially high numbers in the United States. But when this report recalculated the rates to exclude such births equally in all countries, we still ranked last.

Things don't get better after birth. The chance that a child in the United States will die before age 5 is higher than in any of the other 16 peer countries. Injuries are the most common cause of death, but the United States also has the highest rate of deaths caused by negligence or abuse.

And violence is decidedly an American problem. Homicide is the third most common cause of death in children age 1-4.

From age 5-19, the trend continues. Kids this age in the United States have the worst health ranking of the 17 studied countries. More than one-third of U.S. children age 5-17 are obese or overweight, the highest of any peer country. The adolescent pregnancy rate in the United States is about 3.5 times the average of others. Additionally, the rates of sexually transmitted infections, including syphilis, gonorrhea and chlamydia are the worst compared to peer countries.

Nor are these children exempt from death. Injury deaths are more common in 15- to 19-year-olds in the United States than in any other studied country. Homicide claims the second highest number of lives in 15- to -24-year-olds, and 4 in 5 of those deaths involve guns. Males between the ages of 15 and 19 are five times as likely to die from violence in the United States than in other countries.

Even as young adults, ages 25-34, mortality remains consistently upsetting and preventable. Unintentional injuries remain the No. 1 cause of death. The risk of dying by violence remains seven times higher for males in the United States ages 20-24 than in other countries.

We have to work together to make these numbers better. Some of them can be improved with public health measures. We need to help Americans be less obese, to have fewer accidents and to commit less violence. There are lots of local studies and initiatives that propose ways to fix these things, but our public health system is woefully underfunded, and translating any promising findings to meaningful societal change poses a huge challenge.

We also need to improve our safety nets to help children at the lowest end of the socioeconomic ladder do better, even before they are born. Pregnant women, babies and children suffer from hunger and malnutrition far too often in the richest country in the world. Yet we still debate the merits of the federally funded WIC (Womens, Infants and Children) program, school lunches and food assistance to needy families.

Finally, we need to find a way to improve access to the health care system. The Medicaid program covers one in every three births and one in every three children in the United States, and it's still not enough. As some states balk at expanding Medicaid to cover many of the poorest uninsured, some are still talking about reducing funding to the already stretched program. There's no question that we have the capability, the knowledge and the resources to care for people. It's just a matter of doing it better.

There will be some who deny these results. Others will try to use them for political gain. That would be a mistake. We have to accept these findings and begin to work holistically to improve them. Being last just isn't the American way.

Pa. VA hospital knew of bacteria problem before death

(CBS News) There's been an outbreak other than the flu at the VA Hospital in Pittsburgh. It raises the question: What do patients have the right to know?

The bacterium that causes the respiratory illness known as Legionnaires' disease was found in the hospital's water system. The hospital and government officials knew about the outbreak but not the patients who were admitted there.

In November, 87-year-old William Nicklas, a Navy veteran, felt nauseated from medication. He went to the Pittsburgh VA hospital. His sons, Bob and Dave Nicklas, weren't particularly concerned.

"He had full trust in the VA," Dave said. "He was loyal to the military, loyal to the treatment he would receive there.It should be the best care in the world."

But in the hospital, he picked up an infection.

"The doctors wanted to meet with us Wednesday night. The family got together, and that's when she told us it was the Legionella bacteria that was the infection," Bob said.

William fought for his life for three days. The day after Thanks giving he was dead. His family thought they would be bringing him home.

What the family didn't know when William checked in was that the Pittsburgh VA had been battling an outbreak of Legionnaires' disease. There were at least four infections before William, and the outbreak had been reported in the hospital's water nearly a year before his death.

The manufacturer of the hospital's Legionella prevention equipment, Liquitech, claims that in December 2011 the Pittsburgh VA told them it had a Legionella problem. In emails, Liquitech wrote the had been made aware of the bacteria and an investigation showed the hospital systems were not being properly maintained.

"If they knew that there was an outbreak at that hospital then you've got two other, you know, world renowned hospitals located directly across the street from the Veterans Hospital," Dave said. "They could have easily transferred those patients so they weren't exposed."

The hospital did report the problem to the county health department and the federal Centers for Disease Control, but it wasn't until two weeks after William was admitted that it went public. It acknowledged that patients had contracted Legionnaire's disease in the hospital. Two weeks later, the hospital announced 24 more were treated there, but the hospital said the origin of 16 of those infections was unknown.

"The facility has worked... to formulate a plan to suppress the Legionella. Testing results indicate remediation... has been successful," Pittsburgh VA said in a statement, declining an interview.

A federal investigation has begun into whether the hospital was prudent in protecting its patients. The hospital said it is under no legal requirement to report Legionnaires' disease cases or outbreaks to the public or its patients. The Nicklas family plans to sue.

Obama Promises Faster Transition in Afghanistan

President Obama and Afghan President Hamid Karzai said today that most U.S. combat operations in Afghanistan would end this spring, signaling a quickening troop drawdown that will bring the decade-long war to a close at the end of 2014.

"Our troops will continue to fight alongside Afghans when needed, but let me say it as plainly as I can: Starting this spring, our troops will have a different mission -- training, advising, assisting Afghan forces," Obama announced at an East Room news conference in Washington.

"It will be a historic moment and another step toward full Afghan sovereignty, something I know that President Karzai cares deeply about, as do the Afghan people," he said.

Administration officials said Afghan forces were "exceeding initial expectations" in their capabilities. Afghan security forces are expected to lead 90 percent of security operations across the country in February.

"By the end of next year -- 2014 -- the transition will be complete," Obama said. "Afghans will have full responsibility for their security, and this war will come to a responsible end."

The rosy assessments belied the serious political, economic and security challenges that remain.

Left unanswered by Obama and Karzai: How many U.S. troops might stay after 2014; what their mission would be and whether they could be effective; and whether the forces would have immunity from prosecution in Afghan courts.

Obama said he was still reviewing recommendations from the Pentagon and will make an announcement in the coming weeks after penning an anticipated bilateral security agreement with Afghanistan. Karzai said the exact number would be up to the United States to decide.

Both leaders confirmed in a statement that the United States "does not seek permanent bases in Afghanistan."

They also agreed today to turn over battlefield combatants held by the U.S. military in Afghanistan to Afghan government control, which has been long-sought by Karzai.

Roughly 66,000 U.S. troops are serving in Afghanistan. The military has proposed keeping several thousand troops in the country after 2014 as advisers, trainers and logistical support for Afghan forces; the White House has said it remains open to pulling out all troops entirely.

Obama's visit with Karzai was the first face-to-face encounter since the November election and since last year's dramatic increase in so-called green-on-blue attacks, when U.S. and NATO soldiers have been killed by the Afghans they are training or working alongside.

There were 45 insider attacks in 2012 that resulted in 62 deaths among coalition forces, including 35 Americans. There has been one attack already in the first 11 days of 2013.

The White House summit included a private Oval Office meeting between Obama, Karzai and Vice President Joe Biden. The trio also attended a private lunch in the Old Family Dining Room.

Karzai Thursday attended meetings with Defense Secretary Leon Panetta and top military brass at the Pentagon, where he was afforded all the pomp and circumstance accorded a head of state: a 21-gun salute, and marching bands and honor guards from the Army, Navy, Air Force, Marines and Coast Guard.

Karzai's relationship with the United States has at times been a rocky one as he has sometimes made critical statements about the allied troop presence in his country. U.S. officials believe he has made those comments out of political expediency to improve his standing with Afghans and show his independence.
