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.

U.S. consumers are so strained they put more than $1B on BNPL during Black Friday and Cyber Monday

Published

on



Financially strained and cautious customers leaned heavily on buy now, pay later (BNPL) services over the holiday weekend.

Cyber Monday alone generated $1.03 billion (a 4.2% increase YoY) in online BNPL sales with most transactions happening on mobile devices, per Adobe Analytics. Overall, consumers spent $14.25 billion online on Cyber Monday. To put that into perspective, BNPL made up for more than 7.2% of total online sales on that day.

As for Black Friday, eMarketer reported $747.5 million in online sales using BNPL services with platforms like PayPal finding a 23% uptick in BNPL transactions.

Likewise, digital financial services company Zip reported 1.6 million transactions throughout 280,000 of its locations over the Black Friday and Cyber Monday weekend. Millennials (51%) accounted for a chunk of the sizable BNPL purchases, followed by Gen Z, Gen X, and baby boomers, per Zip.

The Adobe data showed that people using BNPL were most likely to spend on categories such as electronics, apparel, toys, and furniture, which is consistent with previous years. This trend also tracks with Zip’s findings that shoppers were primarily investing in tech, electronics, and fashion when using its services.

And while some may be surprised that shoppers are taking on more debt via BNPL (in this economy?!), analysts had already projected a strong shopping weekend. A Deloitte survey forecast that consumers would spend about $650 million over the Black Friday–Cyber Monday stretch—a 15% jump from 2023.

“US retailers leaned heavily on discounts this holiday season to drive online demand,” Vivek Pandya, lead analyst at Adobe Digital Insights, said in a statement. “Competitive and persistent deals throughout Cyber Week pushed consumers to shop earlier, creating an environment where Black Friday now challenges the dominance of Cyber Monday.”

AI labs like Meta, Deepseek, and Xai earned worst grades possible on an existential safety index

Published

on



A recent report card from an AI safety watchdog isn’t one that tech companies will want to stick on the fridge.

The Future of Life Institute’s latest AI safety index found that major AI labs fell short on most measures of AI responsibility, with few letter grades rising above a C. The org graded eight companies across categories like safety frameworks, risk assessment, and current harms.

Perhaps most glaring was the “existential safety” line, where companies scored Ds and Fs across the board. While many of these companies are explicitly chasing superintelligence, they lack a plan for safely managing it, according to Max Tegmark, MIT professor and president of the Future of Life Institute.

“Reviewers found this kind of jarring,” Tegmark told us.

The reviewers in question were a panel of AI academics and governance experts who examined publicly available material as well as survey responses submitted by five of the eight companies.

Anthropic, OpenAI, and GoogleDeepMind took the top three spots with an overall grade of C+ or C. Then came, in order, Elon Musk’s Xai, Z.ai, Meta, DeepSeek, and Alibaba, all of which got Ds or a D-.

Tegmark blames a lack of regulation that has meant the cutthroat competition of the AI race trumps safety precautions. California recently passed the first law that requires frontier AI companies to disclose safety information around catastrophic risks, and New York is currently within spitting distance as well. Hopes for federal legislation are dim, however.

“Companies have an incentive, even if they have the best intentions, to always rush out new products before the competitor does, as opposed to necessarily putting in a lot of time to make it safe,” Tegmark said.

In lieu of government-mandated standards, Tegmark said the industry has begun to take the group’s regularly released safety indexes more seriously; four of the five American companies now respond to its survey (Meta is the only holdout.) And companies have made some improvements over time, Tegmark said, mentioning Google’s transparency around its whistleblower policy as an example.

But real-life harms reported around issues like teen suicides that chatbots allegedly encouraged, inappropriate interactions with minors, and major cyberattacks have also raised the stakes of the discussion, he said.

“[They] have really made a lot of people realize that this isn’t the future we’re talking about—it’s now,” Tegmark said.

The Future of Life Institute recently enlisted public figures as diverse as Prince Harry and Meghan Markle, former Trump aide Steve Bannon, Apple co-founder Steve Wozniak, and rapper Will.i.am to sign a statement opposing work that could lead to superintelligence.

Tegmark said he would like to see something like “an FDA for AI where companies first have to convince experts that their models are safe before they can sell them.

“The AI industry is quite unique in that it’s the only industry in the US making powerful technology that’s less regulated than sandwiches—basically not regulated at all,” Tegmark said. “If someone says, ‘I want to open a new sandwich shop near Times Square,’ before you can sell the first sandwich, you need a health inspector to check your kitchen and make sure it’s not full of rats…If you instead say, ‘Oh no, I’m not going to sell any sandwiches. I’m just going to release superintelligence.’ OK! No need for any inspectors, no need to get any approvals for anything.”

“So the solution to this is very obvious,” Tegmark added. “You just stop this corporate welfare of giving AI companies exemptions that no other companies get.”

Hollywood writers say Warner takeover ‘must be blocked’

Published

on



Hollywood writers, producers, directors and theater owners voiced skepticism over Netflix Inc.’s proposed $82.7 billion takeover of Warner Bros. Discovery Inc.’s studio and streaming businesses, saying it threatens to undermine their interests.

The Writers Guild of America, which announced in October it would oppose any sale of Warner Bros., reiterated that view on Friday, saying the purchase by Netflix “must be blocked.”

“The world’s largest streaming company swallowing one of its biggest competitors is what antitrust laws were designed to prevent,” the guild said in an emailed statement. “The outcome would eliminate jobs, push down wages, worsen conditions for all entertainment workers, raise prices for consumers, and reduce the volume and diversity of content for all viewers.”

The worries raised by the movie and TV industry’s biggest trade groups come against the backdrop of falling movie and TV production, slack ticket sales and steep job cuts in Hollywood. Another legacy studio, Paramount, was sold earlier this year.

Warner Bros. accounts for about a fourth of North American ticket sales — roughly $2 billion — and is being acquired by a company that has long shunned theatrical releases for its feature films. As part of the deal, Netflix co-CEO Ted Sarandos has promised Warner Bros. will continue to release moves in theaters.

“The proposed acquisition of Warner Bros. by Netflix poses an unprecedented threat to the global exhibition business,” Michael O’Leary, chief executive officer of the theatrical trade group Cinema United, said in en emailed statement Friday. “The negative impact of this acquisition will impact theaters from the biggest circuits to one-screen independents.”

The buyout of Warner Bros. by Netflix “would be a disaster,” James Cameron, the director of some of Hollywood’s highest-grossing films in history including Titanic and Avatar, said in late November on The Town, an industry-focused podcast. “Sorry Ted, but jeez. Sarandos has gone on record saying theatrical films are dead.”

On a conference call with investors Friday, Sarandos said that his company’s resistance to releasing films in cinemas was mostly tied to “the long exclusive windows, which we don’t really think are that consumer friendly.”

The company said Friday it would “maintain Warner Bros.’ current operations and build on its strengths, including theatrical releases for films.”

On the call, Sarandos reiterated that view, saying that, “right now, you should count on everything that is planned on going to the theater through Warner Bros. will continue to go to the theaters through Warner Bros.” 

Competition from online outfits like YouTube and Netflix has forced a reckoning in Hollywood, opening the door for takeovers like the Warner Bros. deal announced Friday. Media giants including Comcast Corp., parent of NBCUniversal, are unloading cable-TV networks like MS Now and USA, and steering resources into streaming. 

In an emailed note to Warner Bros. employees on Friday, Chief Executive Officer David Zaslav said the board’s decision to sell the company “reflects the realities of an industry undergoing generational change in how stories are financed, produced, distributed, and discovered.”

The Producers Guild of America said Friday its members are “rightfully concerned about Netflix’s intended acquisition of one of our industry’s most storied and meaningful studios,” while a spokesperson for the Directors Guild of America raised concerns about future pay at Warner Bros.

“We will be meeting with Netflix to outline our concerns and better understand their vision for the future of the company,” the Directors Guild said.

In September, the DGA appointed director Christopher Nolan as its president. Nolan has previously criticized Netflix’s model of releasing films exclusively online, or simultaneously in a small number of cinemas, and has said he won’t make movies for the company.

The Screen Actors Guild said Friday that the transaction “raises many serious questions about its impact on the future of the entertainment industry, and especially the human creative talent whose livelihoods and careers depend on it.”

Oscar winner Jane Fonda spoke out on Thursday before the deal was announced. 

“Consolidation at this scale would be catastrophic for an industry built on free expression, for the creative workers who power it, and for consumers who depend on a free, independent media ecosystem to understand the world,” the star of the Netflix series Grace and Frankie wrote on the Ankler industry news website.

Netflix and Warner Bros. obviously don’t see it that way. In his statement to employees, Zaslav said “the proposed combination of Warner Bros. and Netflix reflects complementary strengths, more choice and value for consumers, a stronger entertainment industry, increased opportunity for creative talent, and long-term value creation for shareholders.”
