The 4 best ways to avoid getting sick while traveling, according to an Olympic doctor

Published

on



With Thanksgiving upon us and even more winter holidays just on the horizon, this week officially kicks off the busiest month of the year for U.S. travelers. And if you’re one of the many people who will be boarding a flight, you may want to take some advice from a physician who has spent years keeping the world’s top athletes healthy.

Dr. Jonathan Finnoff is the chief medical officer of the U.S. Olympic and Paralympic Committee, setting and implementing the organization’s strategic direction for promoting the physical and mental health of Team USA athletes both on and off the field of play. He was named Most Valuable Section Editor by Current Sports Medicine Reports, the medical journal from the American College of Sports Medicine, in 2019. He’s served as medical director for the Mayo Clinic Sports Medicine Center in Minneapolis, worked as a team physician for the NBA’s Minnesota Timberwolves and WNBA’s Lynx, and has accompanied Team USA to multiple Olympic Games. He also happens to be an athlete himself—an accomplished mountain biker.

In an interview with The Wall Street Journal published earlier this month, and an accompanying TikTok video posted Monday, Finnoff shared four key ways to ensure you don’t catch something nasty during your flight.

Choose the right seat

Seats matter—not just to get on and off the plane faster, but also to keep you healthier.

Finnoff says if you want to steer clear of germs, choose a window seat, and try to find one towards the middle of the aircraft. This ensures you stay away from the plane’s high-traffic areas, like the entrance of the plane and the bathrooms.

Research supports Finnoff’s recommendation. A 2018 study published in the Proceedings of the National Academy of Sciences by Emory University and Georgia Tech researchers found that sitting in a window seat—and staying seated for the duration of the flight—may be your best bet for not getting sick from fellow passengers.

The study tracked movements in the economy cabin during transcontinental flights and found that passengers in window seats were far less likely to get up during flights, with only about 40% doing so compared to 80% of those in aisle seats. Window-seaters also averaged just 12 contacts with other passengers per flight, compared to 64 for aisle seaters.

​Clean a select few areas

If Naomi Campbell does it, maybe you should, too. We’re not talking about walking the runway here, but rather bringing sanitizing wipes onto your flights. Finnoff recommends sanitizing any areas you might touch: the seatbelt, armrests, air nozzle, and even the bathroom door, should you (likely) need to use the facilities.

But the most critical surface you should clean? The tray table.

According to a 2015 study by TravelMath, which sent a microbiologist to collect samples from five airports and four flights, tray tables harbored 2,155 colony-forming units of bacteria per square inch—more than eight times the bacteria found on lavatory flush buttons, which registered just 265 colony-forming units.

For comparison, a typical home toilet seat has roughly 172 colony-forming units per square inch.

The discrepancy exists in part because airline crews have limited time between flights for thorough cleaning, while restrooms are cleaned more frequently.

​Every seat has an air nozzle. Use it.

Finnoff made special mention of the overhead air vent. What you want to do is direct the air nozzle between you and the person next to you to create a barrier for germs.

While research on whether individual air vents significantly reduce transmission risk has shown mixed results—with European and American health authorities offering differing guidance—some experts believe the turbulence created in your personal air space may help prevent particles from landing on you.

Most modern aircraft cabins already employ hospital-grade HEPA filters that remove 99.97% of particles, including bacteria and viruses, with air renewed 20 to 30 times per hour.

​The science of sleep

Sleep. Yes, sleep. It’s not just nice to help shut out the world—and your fellow, albeit likely obnoxious, travelers around you—but it also boosts your immune system. Like most research out there will tell you, Finnoff says travelers need seven to eight hours of restful sleep each night to help prevent illness.

A study published in the Journal of Experimental Medicine found that sleep alters the structure of DNA inside immune stem cells, and consistently getting less than seven hours can increase inflammation and susceptibility to disease. According to Yale Medicine, those who chronically get less than seven hours of sleep are three times as likely to develop the common cold compared to those who routinely get eight hours or more.

Wall Street is talking about whether Trump’s Greenland plan will end U.S. ‘primacy’

Published

on



Investors reacted emphatically to President Trump’s insistence that he won’t back down on his plan to take over Greenland: They hate it. The S&P 500 fell 2% yesterday, even though 81% of its companies have beaten their Q4 earnings expectations so far. The dollar fell off a cliff, losing nearly 1% of its value against a basket of foreign currencies. U.S. bond prices weakened modestly. Gold, the safe-haven investment, hit yet another new record high.

The “sell America” trade is in full effect, in other words. S&P futures were up marginally this morning, suggesting that the bloodletting has been put on hold until traders hear what Trump has to say at the World Economic Forum in Davos later today. Trump offered a small ray of hope before he left for Switzerland when he told NewsNation, “We’ll probably be able to work something out.”

The drama has started a global debate about ending America’s “primacy” as the place for investors to hold assets. Increasingly, analysts and economists are talking about hedging against U.S. risk and deploying their capital in markets which are more predictable. The fact that the S&P 500 underperformed last year compared to markets in Asia and Europe is helping make the case. It’s a rerun in 2026, too. The S&P is down 0.71% year-to-date, while the Europe STOXX 600 is up 0.69% and the South Korean KOSPI is up an astonishing 14%.

“Until the US no longer ‘threatens’ with the use of tariffs … the so-called ‘primacy’ of the U.S. remains at risk of further dissolution, and with it an upending of the geopolitical alignments that have upheld markets in recent years,” Macquarie analysts Thierry Wizman and Gareth Berry wrote in a recent note to clients.

Their argument—perhaps one of the most extreme ones that Fortune has ever seen in an investment bank research note—is that when the U.S. goes through a major political convulsion a period of stagnation follows, and thus investors should begin moving their money away from America:

“A line can be traced, for example, from the failure of the U.S. in the Vietnam War and the follow-on decline in U.S, primacy, to the U.S.’s gold reserve depletion, and the subsequent end of the fixed exchange rate system under the Bretton Woods Agreement of 1944. The ‘fiat money’ era that followed was associated with a large decline in the real value of the USD, from 1971 until 1981, as well as a period of inflation and recessions across the 1970s,” they said. 

“We should worry about the USD and its relation to other currencies, too. If the reserve status of the USD does depend on the U.S. role in the world—as guarantor of security and a rules-based order—then the events of the past year, and of the past three weeks, in particular, carry the seeds of a reallocation away from the USD, and the search for alternatives, especially among reserve managers. So far, allocators have only found solace in gold, but they may eventually move toward other fiat currencies, too.”

Wall Street got a glimpse of what this might look like when the Danish retirement savings fund AkademikerPension said yesterday that it would sell its $100 million stake in U.S. bonds by the end of the week.

So far, traders are flinching at Trump’s actions. But we haven’t yet seen the kind of full-scale capital flight away from U.S. assets that might, for instance, raise inflation, interest rates or trigger a recession. But the mere fact that Wall Street is discussing it is significant.

Deutsche Bank’s George Saravelos told clients in a note at the weekend: “Europe owns Greenland, it also owns a lot of Treasuries. We spent most of last year arguing that for all its military and economic strength, the U.S. has one key weakness: it relies on others to pay its bills via large external deficits. Europe, on the other hand, is America’s largest lender: European countries own $8 trillion of US bonds and equities, almost twice as much as the rest of the world combined. In an environment where the geoeconomic stability of the western alliance is being disrupted existentially, it is not clear why Europeans would be as willing to play this part. Danish pension funds were one of the first to repatriate money and reduce their dollar exposure this time last year. With USD exposure still very elevated across Europe, developments over the last few days have potential to further encourage dollar rebalancing.”

This note was internally controversial. Deutsche Bank CEO Christian Sewing had to call U.S. Treasury Secretary Scott Bessent to disavow it.

The CEO does not stand by it but Saravelos’s colleagues may be more sympathetic. Jim Reid and his team, who religiously send an early morning email summarizing market action, did not send their email this morning. The bank told Fortune, “Deutsche Bank Research is independent in their work, therefore views expressed in individual research notes do not necessarily represent the view of the bank’s management.”

In fact, the idea that Europe might move out of U.S. assets is a commonplace inside investment banks right now. At UBS, Paul Donovan told clients earlier this week, “The implications of additional tariffs are more U.S. inflation pressures and a further erosion of the USD’s status as a reserve currency. So far, bond investors do not seem to be taking the threats too seriously.”

This morning he said that the most likely scenario wouldn’t be investors selling U.S. debt but simply refusing to buy new debt, thus reducing the flow of funds that the America is dependent on.

In a tariff war, one under-discussed weapon at Europe’s disposal is its Anti-Coercion Instrument: It has the power to ban U.S. services businesses from the E.U.

“U.S. services exports to the E.U. were $295B in 2024, equivalent to 0.9% of US GDP, suggesting the harm could be much greater if the E.U. pulled this relatively new lever at its disposal than if it responded simply with tariffs, though its economy would be hurt more too,” Pantheon Macroeconomics analysts Samuel Tombs and Oliver Allen told clients.

“In short, nobody would win from a new trade war, but the E.U. has ample scope to harm the U.S. if the Greenland situation escalates,” they said.

Here’s a snapshot of the markets ahead of the opening bell in New York this morning:

  • S&P 500 futures were up 0.19% this morning. The last session closed down 2.06%.
  • STOXX Europe 600 was down 0.4% in early trading.
  • The U.K.’s FTSE 100 was flat in early trading. 
  • Japan’s Nikkei 225 was down 0.41%.
  • China’s CSI 300 was flat. 
  • The South Korea KOSPI was up 0.49%. 
  • India’s NIFTY 50 was down 0.3%. 
  • Bitcoin was down to $89K.

Match Group says a ‘readiness paradox’ is crippling Gen Z in dating

Published

on



Gen Z is sometimes criticized for its proclivity toward slang or its approach to the workforce. But this generation is facing challenges very different from those of their elders. The young adults are slowing down their pursuit of the American Dream of finding “the one,” owning a home, and having kids.

But it’s not because Gen Z doesn’t want to find love, according to a report by Match Group and Harris Poll shared exclusively with Fortune. In fact, their survey results from 2,500 randomly selected U.S. adults shows 80% of Gen Z say they believe they’ll find true love, making them the most optimistic generation about finding love. Yet, only 55% of Gen Z feel like they’re actually ready for partnership. 

Therein lies the “readiness paradox,” a phenomenon that paralyzes Gen Z from taking that initial step toward a serious relationship, and subsequently toward marriage and having children. While more than half of Gen Z says they feel lonely despite having online connections, 48% of Gen Z women report feeling additional pressure to enter a relationship for “the right reason,” rather than solely to avoid loneliness. This cycle traps young people in loneliness, which is amplified by social media pressures, like the dread of “hard-launching” a relationship. 

“It makes total sense to be stuck in that paralysis of, I want this, I want a relationship, but I don’t feel ready for it, and so I don’t do it,” Chine Mmegwa, head of strategy, corporate development, and business operations at Match Group, told Fortune. “What they’re afraid of is failing. What they’re afraid of is that the other person on the other side isn’t ready.”

Match Group defines this phenomenon as a “self-reinforcing cycle” in which Gen Zers set a high bar for readiness for a relationship, then feel anxious about being alone, then crave new relationships, believe they’re not ready for it and wait longer, experience more loneliness, and then the cycle repeats. 

And some of this cycle stems from the fact that Gen Z prioritizes investing in personal growth, therapy, and defining success over other generations. Nearly 60% of Gen Z women say therapy is essential to relationship success, according to the Match Group report, and almost 50% say that setting and respecting healthy boundaries is a prime indication of being ready for a romantic relationship. And as a result, they may be more likely to delay dating. 

This report serves as a launchpad for Match Group and other dating app companies to rethink how to best serve Gen Z consumers, some of which had ditched the apps when they did have features they could relate to. But now Tinder has introduced more casual modes for Gen Zers to meet each other, like through its double-date feature and college mode where the generation can meet more people with the same relationship goals in mind.

That’s a step in the right direction for a generation that is reverting back to a desire to meet in real life.

“This is the way Gen Z wants to connect,” Match Group CEO Spencer Rascoff previously said. “They want to vibe their way through meeting people.”

Reprioritizing milestones

Unlike how some other reports about Gen Z love life have portrayed the generation, they’re not rejecting romance. Instead, they’re reshuffling life’s timeline amid economic and social strains. 

Match Group’s report shows nearly half of Gen Z say they’re not ready for relationships now, and 75% aren’t rushing into one. But, again, 80% say they believe they’ll find true love.

“They believe that when they work on themselves, their relationships become stronger,” according to the Match Group report. “And they are more likely to wait until they can put their best selves forward to give themselves the highest chance of relationship success.”

Although that may sound like worrisome news for a company trying to appeal to the latest generation, Mmegwa didn’t shy away from the challenge. 

Gen Z is “still looking to our products to solve real big issues. And they are still looking to our products and to dating to solve the things that are most important to them” she said. “It’s just a question of when and how they will use our products that [is] very different from prior generations.”

This generation also has a very different view of how happy their own parents’ and grandparents’ relationships are: Only 37% described those relationships as happy, and 34% of Gen Z women also feel working through issues from past relationships indicates readiness, according to the report.

Social media’s vicious cycle

Being highly inundated by and invested in social media has also exacerbated the readiness paradox. While 46% of Gen Z “soft-launch” relationships versus 27% overall, 81% see it as an ironclad agreement, and dread backlash from a public failure. 

It’s different from how other generations view making relationships public: “You can also hard launch and then delete the photos the next day, and it’s okay,” Mmegwa said. 

But still, for Gen Z, relationship performance pressure creates a cycle: High readiness bars lead to loneliness, which ultimately leads to them pursuing lower-stakes or casual relationships that rarely escalate into something more serious.

Instagram exacerbates the stall. While 46% of Gen Z “soft-launch” relationships versus 27% overall, 81% who hard-launch see it as an ironclad commitment, dreading public failure. Mmegwa highlighted this generational shift: “You can also hard launch and then delete the photos the next day, and it’s okay.” This “performance pressure” creates a cycle: High readiness bars lead to loneliness (over 50% feel it despite online ties), prompting low-stakes connections that rarely escalate.​

“For us, the focus is on how we bring people together and encourage them to return to in-person connections,” Hinge CEO Jackie Jantos previously told Fortune. Hinge is part of Match Group, along with Tinder, Match, and OkCupid.

How Match Group plans to address the readiness paradox

Match Group is planning to meet Gen Z where they are: They’ll keep introducing “low-pressure” tools, like Tinder’s Double Dating feature and College Mode.

“The idea here is really around helping our users have the power to control what they’re looking for in a given moment and be able to find that more easily,” Cleo Long, Tinder’s senior director of global product marketing, previously told Fortune.

Using the report as a roadmap for new product plans, future features could include features like readiness signals, Mmegwa said, and more curated matches will be important. 

“It’s no longer a speed and volume game,” she said. “It’s [about] truly making our algorithms help you know yourself better, and then help you know the person on the other side of the connection better.”

As risk skyrockets, current and former CFOs are in demand for audit committees

Published

on



Good morning. As audit committees confront a rapidly expanding risk landscape, their role in corporate governance is being reshaped. Boards have often turned to current and former CFOs as independent directors, particularly for audit committees, because of their ability to translate complex operational and financial realities into effective oversight.

For example, this month, J. Michael Hansen, former EVP and CFO of Cintas Corporation, was appointed to the audit committee at Paychex. In July, Britt Vitalone, EVP and CFO of McKesson Corporation, was appointed to the audit committee of Align Technology’s board of directors. And in November, Catherine Birkett, CFO of GoCardless, was named chair of the audit and risk committee at Twinkl.

I attended the launch event of the Institute of Internal Auditors’ (IIA) Global Audit Committee Center last week in Washington, D.C., which addressed the challenges and opportunities facing audit committees.
The center is designed to be a resource to strengthen the alliance between audit committees of boards and internal audit in a fast-changing risk environment. It offers research, webinars, and events and will ultimately add formal training programs.

“The center has a very strong core belief—well-informed, engaged, and well-supported audit committees are essential to corporate governance,” said Anthony Pugliese, president and CEO of the IIA.

Pugliese emphasized that board audit committees need to turn to internal audit to truly understand what is happening inside an organization. The event drew members from across the U.S. and around the world, including Canada, Europe, Africa, Latin America, and the Middle East, with Abdullah Alshebeili, CEO of the Saudi Authority of Internal Auditors, in attendance.

CFOs, in particular, work with internal audit on risk assessment, internal controls, and audit readiness, and they share information on financial processes and control issues. Finance chiefs also communicate regularly with the board’s audit committee.

AI and analytics reshape how audit committees see risk

During a panel discussion at the event, Ann Cohen, CFO of the IIA, said audit committees are increasingly using AI and advanced technology to connect different types of risk—third-party, financial, operational, cyber, and regulatory. They are using analytics to surface anomalies and emerging risks earlier, support proactive oversight, and run “what if” analyses before risks materialize. “It allows us to be more responsive to risks and provide more robust assurance to stakeholders,” she said.

A major focus is “everyday AI,” said Sarah Francis of the EY Center for Board Effectiveness. “I think audit committees are really also looking at, ‘How do we start to touch, feel, smell, and get used to the products that are out there?’” Directors, many of whom are active executives, are also thinking about how to deploy these tools effectively. “There have to be clear governance frameworks for AI and analytics,” she said, noting that prompts—and the people who craft them—matter. She highlighted the need for experts who can help frame broader questions around ethics within responsible AI frameworks.

Audit committees can and should engage with technology as they work toward a fully defined plan, commented Luke Whorton, executive search and leadership consultant at Spencer Stuart in the firm’s Financial Officer Practice. “How do you create a foundation, but one that’s agile and responsive, because it’s going to continue to change rapidly?” he asked.

“Audit committees need to be curious,” Cohen said. “They need to challenge management on their inputs, on their assumptions and their judgment, and on what they’ve embedded into their AI outputs.”

The committees that challenge assumptions and lean into technology, alongside strong partnerships with internal audit, could be well-positioned to safeguard trust in an uncertain world.
