Setting Up Your Home Office

The more you work out, the fitter you'll get. Your VO2max, sometimes described on wearables as a "cardio fitness" score, is a number that tends to be higher among people who are more cardiovascularly fit. But it's not the only measure of fitness, and you should know what it really means. What VO2max really is (as measured in a lab)Smartwatches and fitness trackers don't actually measure VO2max; they just estimate it. To actually find your VO2max, you'd need to go to an exercise lab and do a test on a treadmill or cycle while hooked up to equipment that measures your heart rate and the air you're exhaling. I did exactly this kind of test to compare my real VO2max to the n…

We may earn a commission from links on this page. A healthy dose of cardio is an important part of your exercise routine, and for a lot of us, "zone 2" cardio is going to make up a big chunk of that. Low-intensity cardio—sometimes called LISS or “zone 2”—used to be an underrated form of exercise. It's super trendy now, after spending years on the sidelines while HIIT and lifting-only routines ran the field. But what is zone 2 cardio, exactly? How can you make sure you're doing it right? And is it really so bad if your heart rate drifts into zone 3? What is zone 2 training?Zone 2 training is cardio done at a steady, low intensity. It has benefits for aerobic training (so …

We may earn a commission from links on this page. Last week I ran the D.C. half-marathon alongside nearly 8,000 other runners. While I generally love running with my Garmin Forerunner 165 (which I've previously reviewed), when I strapped the watch on the morning of the race, I had some reservations. This watch has earned a reputation as a barebones beginner device—and I was worried if it would hold up when it really mattered. Would the GPS remain accurate throughout the 13.1 mile run? Would the pacing features actually help me hit my goal time? After crossing the finish line, I'm happy to report that this entry-level watch met my expectations in almost every way. …

Intrauterine devices, or IUDs, are an extremely effective and convenient form of birth control for many people—but it can also very painful to get one inserted. Current medical guidelines say that your doctor should be discussing pain management with you, and they also give advice to doctors on what methods tend to work best for most people. The newest set of guidelines is from ACOG, the American College of Obstetricians and Gynecologists. These guidelines actually cover a variety of procedures, including endometrial and cervical biopsies, but today I'll be talking about the IUD insertion portions. And in 2024, the Centers for Disease Control and Prevention's released ne…

Did you know you can customize Google to filter out garbage? Take these steps for better search results, including adding my work at Lifehacker as a preferred source. I usually focus on something a subset of the population gets wrong, so the rest of us can feel smart, but this week, I’m going bigger and broader, and describing something that you, me, and everyone we have ever met has been wrong about in the past, is currently wrong about, and will be wrong about in the future: mistaking correlation for causation. People have been repeating some variation of "correlation is not causation" since at least 1739, when David Hume articulated the concept in A Treatise on Human N…

Football season is in full swing, but these are such strange days that even of game day, Americans can no longer put their political differences aside to enjoy the savage ballet. Yes, the National Football League has once again become a flashpoint in the endless, maddening culture wars—and surprisingly, the NFL seems to be on the "woke" side of the board. Right now, there's a lot of misinformation being spread about the game, the league, and the personalities within. Here are some of the biggest I've encountered. Did Andy Reid refuse pledge to not attend the 2026 Super Bowl over a planned Charlie Kirk tribute?The questionable Facebook pages of both Kollam's Media and Tog…

To the disappointment of Judgment Day fans, The Rapture did not happen as predicted at the end of September, but keep your fingers crossed for November, when aliens are expected to invade. This one's a way more concrete prediction than the Rapture. Unlike Jesus, we can actually see the alien starship in our telescopes, cleverly disguised as an interstellar comet. And it's not just conspiracy theorists or Joe Rogan Podcast guests sounding the alarm—a Harvard astrophysicist kicked off the whole thing. So hold on to your butt! The ballad of 3I/ATLASBack in July, NASA spotted 3I/ATLAS, an interstellar comet about the size of M…

Smashing Pumpkins' legendary frontman Bill Corgan and confrontational comedian Bill Burr look alike—both have shaved heads, stubbly beards, blue eyes, and similar facial structures. They look so much alike they could be brothers; so much alike that a lot of people think they are brothers. While it's possible, these people are probably wrong. Why people think Bill Corgan and Bill Burr are brothersThe rumor started with Corgan's appearance on Howie Mandel's podcast back in January. On the show, Corgan recounts the following conversation that he said happened a decade prior: My stepmother said to me, "Do you know who Bill Burr is?" Now at that point, I had never heard of Bil…

On Feb. 11, "volunteer IT consultant" Elon Musk appeared at an Oval Office event to discuss the findings of the newly formed Department of Government Efficiency. Among other claims, Musk said that a "cursory examination of Social Security” revealed that people who are clearly dead may be receiving social security benefits. “We’ve got people in there that are 150 years old,” Musk said “Now, do you know anyone who’s 150? I don’t, OK… I think they’re probably dead, is my guess, or they should be very famous, one of the two.” In a later post on X, Musk provided some numbers and joked, "Maybe Twilight is real and there are a lot of vampires collecting Social Security." …

Did you know you can customize Google to filter out garbage? Take these steps for better search results, including adding my work at Lifehacker as a preferred source. This past Saturday night, someone, presumably the President of the United States, posted a video clip to Donald The President's TruthSocial account that seemed to show the President appearing on Fox News' My View with Lara The President to announce "America's first MedBed hospitals," as well as the imminent release of "MedBed cards" so Americans can access said hospitals. "These facilities are safe, modern, and designed to restore every citizen to full health and strength," The President says in the clip. …

Maybe it's not fair to call a medical diagnosis "trendy," but more and more adults in the U.S. are seeking treatment for attention deficit hyperactivity disorder. ADHD, once regarded as a childhood disease, has made the transition to adulthood: About 15.5 million adults in the U.S. have been "officially" diagnosed with the disorder, and a growing group of others believe they have ADHD. A lot of them are wrong, but that's OK. Fed by a steady stream of online influencers and pop science, more and more people are self-diagnosing with ADHD, autism, depression, and other mental disorders. Very few of them are qualified to make these diagnoses. While it’s easy to scoff at some…

A few weeks ago, I posted a story about the proliferation of AI-created fake news videos about Press Secretary Karoline Leavitt. Because I am fair (and balanced!), this week I'm looking at the AI distortion of a hero from the left: Dallas-based congressperson Jasmine Crockett. The real Crockett is sharp, confrontational, and isn't afraid to curse people out. AI-Jasmine Crockett is a folk hero who spends her life STUNNING, DESTROYING, and OBLITERATING various talk show hosts, actors, and political opponents. She took on Bill Maher, humiliated Seth Meyers, made Ellen DeGeneres regret insulting her, and still had time to have a judge arrested. On YouTube. The real Jasmine …

There’s a new star in the firmament of fake new: White House Press Secretary Karoline Leavitt. Known for her combative press conferences, Leavitt is at the center of a tornado of misinformation that is being spread on both sides of the political spectrum. To set the record straight on two of the most viral fake Leavitt stories: She did not say people will love tariffs if they “avoid woke things like math.” And she did not appear on the Stephen Colbert Show. So if you believed either of these things, you’re wrong, Before you feel too bad for the lies being told about Leavitt, she is okay with spreading fake news of her own, so it's a huge mess. Karoline Leavitt did not s…

Another week, another "gotcha" video debunked. This time it's "Cop Pulls Over Black Judge and Lives To Regret It," a piece of pseudo-documentary street drama that's been viewed millions of times on YouTube and TikTok (and elsewhere, I'm sure). The video is part of a growing online video genre based on documenting cops' confrontations with public, either through police-worn body camera footage or citizen-filmed footage. Some of these videos are real, but many of them are not. Here's the "Cop Pulls Over Judge" video: The tells: bad improv in a Florida parking lotIf you have a smidge of media literacy, it's easy to spot this as fake. The acting is sub-community-the…

There is a rumor going around online—on Reddit, Facebook, TikTok, and (I assume) Friendster—that gravity will stop working for seven seconds on August 12. Here is part of the warning posted online: In November 2024, a secret NASA document titled "Project Anchor" leaked online. The project's budget is $89 billion, and its goal is to survive a 7-second gravitational anomaly expected on August 12, 2026, at 14:33 UTC Key facts:• Duration: 7.3 seconds.• Expected casualties: 40-60 million. What will happen: 1-2 seconds: Everything not secured will rise (people, vehicles, animals).3-4 seconds: Objects will continue to rise to 15-20 meters.5-6 seconds: Panic and chaos will ensue …

The pre-Super Bowl hype weeks have begun, and with them comes the annual American tradition of calling the NFL rigged. Local drunks, AM radio sports show hosts, and message board experts are all in agreement: The fix is in. Last year, the most interesting conspiracy theory held that the Pentagon rigged the entire 2024 NFL season so the Chiefs could appear in the Super Bowl and Taylor Swift could help Democrats get re-elected in 2024. (Oops.) This year's football truthers have a less esoteric theory for why the Chiefs are definitely going to win the Super Bowl: Follow the money. They make a compelling case, but they're wrong. Why "they" would fix the Super BowlThe rough …

Many people think the world is going to end in 2026. Man people think the world is going to end every year—maybe because the Bible said so, or The Simpsons said so—but this 2026-doomsday prediction seems to have a scientific basis. In a 1960 issue of Science magazine, Austrian scientist and polymath Heinz von Foerster detailed what he called the “Doomsday Equation,” a model he used to calculate the last day of civilization on earth. According to von Foerster (and probably Homer Simpson), The End is coming on Friday, November 13, 2026. Who is Heinz von Foerster?Foerster was not a crank. A pioneer in computer science, artificial intelligence, physics, biophysics, and other…

In a culture overwhelmed with ridiculous beliefs, an unlikely hero of rationality has emerged: reality star Kim Kardashian. Kim raised a healthy amount of skepticism of psychics in a recent TikTok video: In case you don’t follow the ins-and-outs of reality stars, Kim K.'s recent life cycle/plot development sees her trying to become a lawyer. She’s been taking an apprenticeship in the industry and presumably studying hard. She also consulted psychics, who read tea leaves or whatever and concluded that she would pass the California bar exam. Except, sadly, she did not. “Psychics are full pathological liars” —Kim Kardashian“All of the fucking psychics that we have met with,…

A recent outbreak of measles in West Texas has resulted in 159 cases of the disease in the state so far; 22 victims required hospitalization, and one has died. In response to the deadly outbreak, some Texas parents seem to be considering hosting "measles parties" instead of vaccinating their kids. Misinformation about measles can have deadly consequences, so here's a look at some ways people are getting measles wrong. Myth: Measles vaccines are potentially dangerousWhile a small percentage of people suffer side effects from the measles, mumps, and rubella (MMR) vaccine, they are almost always mild. The most common is a fever that hits between 5% and 10% of those vaccinat…

We may earn a commission from links on this page. Every few decades, the pop culture machine spits out a person who purports to have supernatural powers. In the 1980s, it was spoon-bending swami Uri Geller. In the 1990s and 2000s, it was “mediums” like John Edward, who supposedly talked to people’s dead relatives. In 2025, we have Oz Pearlman. To be fair, unlike the rest of these examples, Pearlman doesn't claim supernatural powers himself, but a lot of people seem to be taking his stage patter explanation for his mentalist tricks as the unvarnished truth. They're wrong. Oz (pronounced “Oh’s”) has a hell of a schtick. The 43-year-old dude seems like an unassuming nerd, un…

We are less than two weeks away from the 95th anniversary of the discovery of Pluto, the ice-caked, rocky sphere orbiting around 3.7 billion miles from the sun. To mark the occasion, The Lowell Observatory in Flagstaff, Arizona, where Pluto was discovered, is hosting its sixth annual "I Heart Pluto" festival. But should they? Is Pluto even a planet? According to a recent YouGov poll, 35% of Americans think Pluto is not a planet. It's something else, according to them. But they are all wrong—kind of. To get to the bottom of Pluto's planet status, I tracked down planetary scientist Dr. Will Grundy—who you might recognize from academic papers like "Measurement of D/H and 13…

A recent YouTube video from channel The Ultimate Discovery makes some claims that might surprise fans of actor Gene Hackman. According to the video, FBI agents searching Hackman's home following his death discovered a "hidden passageway concealed behind the library wall" that led to a "vast, eerie underground warehouse" containing documents, antiques, old photographs, and parts of unidentifiable machines. The walls were covered in runes and symbols that seem to be of ancient origin and could not be translated. Not only that, the bunker connects to larger network of tunnels, "similar to the catacombs of Paris." It's a pretty good story (if you can swallow the pre…

This week, there has been a lot of chatter in the weirder parts of the online world about the supposed discovery of a hidden complex of underground chambers beneath the Great Pyramids of Giza in Egypt. It seems a team of researchers announced they'd used SAR (Synthetic Aperture Radar) to reveal a number of underground buildings beneath the Khafre Pyramid. This discovery could offer proof the ancient Egyptian civilization was far more advanced than is generally believed, and possessed technology that rivals our own. It could change everything we think we know about humanity itself! In other words, big if true. Spoiler: It's not true though. All signs point to the “discov…
