The 2026 FIFA World Cup is giving fans an unusual view of football history: several of the game’s biggest names are still competing long after most elite careers have ended.

Cristiano Ronaldo and Lionel Messi are appearing in their sixth World Cups. Ronaldo has scored twice in this tournament and 10 times overall, while Messi has added six goals in 2026 to reach 19 for his World Cup career. Luka Modrić is playing in his fifth tournament. Neymar and Kevin De Bruyne are each appearing in their fourth.

Those numbers say something important about talent. They say even more about durability.

Reaching one World Cup is difficult. Returning four, five or six times means surviving nearly two decades of club schedules, injuries, travel, tactical changes and competition from younger players. It also means finding new ways to contribute when the body no longer responds exactly as it once did.

That opens up several timely questions for journalists covering this final stage of their careers. Below, experts in sports science, biomechanics, psychology and sports business offer perspective on what it takes to compete across multiple World Cups—and what allows some players to remain influential long after their physical peak.

What does it take physically to last this long?

The World Cup lasts only a few weeks, but the careers behind it are built over thousands of training sessions and matches. For older players, the challenge is not simply staying fit. It is managing fatigue, recovering faster and avoiding the injury that could end the run.

Hofstra exercise physiologist Katie Sell can speak to the less visible work behind these careers: sleep, hydration, nutrition, endurance and the tighter recovery window athletes face as they age.

At the University of Delaware, Tom Kaminski brings expertise in soccer injuries, concussions and player safety. He can help explain how accumulated wear, repeated head impacts and return-to-play decisions influence whether a player can continue at the highest level.

Texas Christian University’s Peter Weyand, an expert in sprint mechanics and running performance, can discuss what happens to speed and acceleration over time—and which physical qualities can still be protected through training.

How do great players change their game?

Longevity rarely comes from playing the same way forever.

Ronaldo moved from the wing into a more central scoring role. Messi became more selective with his movement. Modrić continued to control matches through timing, positioning and awareness rather than physical dominance.

These are not signs that aging players have stopped influencing games. They are signs that influence has changed.

Carnegie Mellon biomechanics researcher Eni Halilaj can speak to how athletes adjust their movement patterns, conserve energy and reduce physical strain as they get older, while her colleague Eric Yttri, who studies motor control and decision-making, can explain how anticipation and experience allow veteran players to act earlier and more efficiently.

Texas Christian University’s Peter Weyand can also add context on why older players often change positions, reduce repeated sprinting or become more selective about when they make high-intensity runs.

Why keep coming back?

By the time a player reaches a fourth or fifth World Cup, money and recognition are unlikely to be the main reasons for continuing. The harder question is what keeps an athlete committed after years of success, injuries and public scrutiny—especially when their role may be smaller than it once was.

TCU sport psychology expert Robyn Trocchio can speak to motivation, focus and how accomplished athletes continue setting meaningful goals late in their careers.

Hofstra’s Genevieve Weber can address performance anxiety, media pressure and the emotional weight of entering what may be a final international tournament.

Georgia Southern sport psychologist Brandonn Harris can discuss resilience, confidence and the mental discipline required to recover from injury, disappointment and changing expectations.

How should an aging superstar be judged?

Goals are easy to count. Leadership, timing and influence are not.

A veteran player may no longer dominate every match, but may still shape how teammates prepare, how opponents defend and how supporters respond. For coaches, that creates a difficult balance between reputation, current performance and what an experienced player brings in moments of pressure.

At Emory University’s Goizueta Business School, Michael Lewis can discuss the value of global stars beyond the score sheet, including fan interest, brand strength and the attention they bring to a national team.

Carnegie Mellon University’s Eric Yttri can speak to the on-field contributions that statistics often miss, including positioning, anticipation and decision-making.

Texas Christian University’s Robyn Trocchio can address the leadership side of the story, including the difficult transition from automatic starter to mentor, substitute or situational player.

A generation nearing the end

The 2026 World Cup may be remembered not only for the players who emerged, but for the ones who were leaving.

Ronaldo, Messi, Modrić, Neymar and De Bruyne have played through different tactical eras and alongside multiple generations of teammates. Their longevity was not built on talent alone. It required adaptation, recovery, discipline and a willingness to accept that staying great sometimes means becoming a different kind of player.

For reporters, their careers offer a timely way to examine how elite athletes age—and why some remain relevant long after the normal limits of the game suggest they should.

Pneumonic Plague: An Ancient Killer That Has Never Completely Disappeared

Few diseases carry the historical weight of plague. Caused by the bacterium Yersinia pestis, plague has been responsible for some of the deadliest disease outbreaks in recorded history. The most infamous was the Black Death of the 14th century, which swept through Europe, the Middle East and North Africa and killed tens of millions of people. The World Health Organization estimates that more than 50 million people died in Europe alone. But plague is not simply a disease of the past. The bacterium continues to circulate naturally among wild rodents and their fleas in parts of the world, and human cases still occur. The World Health Organization reports that most cases recorded between 2019 and 2025 occurred in the Democratic Republic of the Congo and Madagascar. What Is Pneumonic Plague? There are three primary forms of plague: bubonic, septicemic and pneumonic. Bubonic plague - historically the best-known form - usually develops following the bite of an infected flea and is characterized by painful, swollen lymph nodes known as “buboes.” Pneumonic plague occurs when Yersinia pestis infects the lungs. It can develop when untreated bubonic or septicemic plague spreads to the lungs, or when someone inhales infectious respiratory particles from a person or animal with pneumonic plague. That distinction is important: pneumonic plague is the only form of plague that can spread directly from person to person through respiratory particles. What Are the Symptoms? Pneumonic plague can progress remarkably quickly. According to the CDC, symptoms include fever, headache and weakness followed by rapidly developing pneumonia. Patients can experience shortness of breath, chest pain and coughing, sometimes producing bloody or watery mucus. Symptoms following inhalation can begin as soon as one day after exposure. Without treatment, pneumonic plague is extremely dangerous. The World Health Organization describes untreated pneumonic plague as invariably fatal, making rapid recognition and medical intervention critical. From Medieval Killer to Treatable Disease What separates plague today from the disease that devastated populations centuries ago is modern medicine. Plague is a bacterial infection and can be successfully treated with antibiotics. The CDC recommends beginning treatment as soon as plague is suspected rather than waiting for laboratory confirmation. Depending on the severity of the illness, treatment can involve intravenous or oral antibiotics, with gentamicin and fluoroquinolones among the first-line treatments used in the United States. Early detection matters enormously. Modern antibiotics, infection-control practices, surveillance and public-health responses mean that a disease once capable of devastating entire communities can now be identified, contained and treated. Yet its persistence also offers an important reminder: diseases that profoundly shaped human history do not necessarily disappear. Plague remains present in animal populations, continues to cause human infections and provides researchers with a remarkable window into the relationship between infectious disease, human behaviour, public health and even human evolution. Experts in infectious diseases, epidemiology, public health, microbiology, global health, medicine and the history of disease can help provide perspective on pneumonic plague, how it spreads, the risks it poses and what centuries of experience with plague can teach us about preventing and responding to outbreaks today.

25 Years Later: How 9/11 Changed the World

On September 11, 2001, the world watched as nearly 3,000 people were killed in terrorist attacks that would become one of the defining moments of the 21st century. Twenty-five years later, 9/11 remains much more than a moment in history. Its consequences continue to shape the world we live in. The attacks transformed national security and intelligence, changed how people travel, reshaped airport and border security, and ushered in a new era of surveillance and counterterrorism. They also profoundly influenced American foreign policy, leading to wars in Afghanistan and Iraq and decades of debate about security, military intervention and America's role in the world. The effects were cultural as well as political. September 11 changed how a generation viewed safety, terrorism and global conflict. It also sparked difficult conversations about civil liberties, immigration, religious tolerance and the balance between individual freedoms and collective security. For younger generations, 9/11 is increasingly an event learned about rather than remembered. For millions of others, memories of where they were and what they saw that day remain remarkably vivid. A quarter-century later, the anniversary offers an opportunity to remember those who were lost, recognize the first responders and countless others affected by the attacks, and examine how the decisions made in their aftermath continue to influence our world. Experts in history, political science, international relations, national security, terrorism, public policy and sociology can help provide perspective on September 11, its legacy and how the world has changed 25 years later.

More Than a Long Weekend: Why Labor Day Still Matters in America

For millions of Americans, Labor Day means the unofficial end of summer , a final long weekend before schools are back in full swing and the fall routine takes over. But behind the barbecues, travel and end-of-summer sales is a holiday rooted in the history of American workers and the transformation of the workplace. Observed on the first Monday in September, Labor Day recognizes the social and economic achievements of American workers. Its origins date to the labor movement of the late 19th century, with the first Labor Day celebration held in New York City on September 5, 1882. In 1894, it became a federal holiday. More than 130 years later, Labor Day remains an opportunity to look at the role work plays in American life, particularly at a time when the workplace itself is undergoing enormous change. Artificial intelligence and automation are reshaping jobs and industries. Remote and hybrid work have changed where and how millions of people work. Employers continue to navigate workforce shortages, recruitment and retention, while workers are reconsidering expectations around compensation, flexibility, benefits and work-life balance. Labor Day can also open the door to broader conversations about the American labor movement, organized labor, workplace protections, wages and the economic contribution of workers. For journalists, that makes the holiday much more than a date on the calendar. It's a timely opportunity to explore both how work in America has changed and where it is heading next. Experts across economics, business, labor relations, history, human resources, public policy and emerging technology can provide valuable perspective on Labor Day and the changing American workplace. Journalists covering Labor Day and looking for expert perspective on the history of the holiday, labor and employment, workplace trends, organized labor, artificial intelligence and the future of work can connect with experts directly through ExpertFile profiles below:
