These should be boom times for sex.

The share of Americans who say sex between unmarried adults is “not wrong at all” is at an all-time high. New cases of HIV are at an all-time low. Most women can—at last—get birth control for free, and the morning-after pill without a prescription.

If hookups are your thing, Grindr and Tinder offer the prospect of casual sex within the hour. The phrase If something exists, there is porn of it used to be a clever internet meme; now it’s a truism. BDSM plays at the local multiplex—but why bother going? Sex is portrayed, often graphically and sometimes gorgeously, on prime-time cable. Sexting is, statistically speaking, normal.

The Amazon HQ2 saga had all the hallmarks of the gaudiest reality TV. It was an absurd spectacle, concluding with a plot twist, which revealed a deep and dark truth about the modern world.

Fourteen months ago, Amazon announced a national beauty contest, in which North American cities could apply to win the honor of landing the retailer’s second headquarters. The prize: 50,000 employees and the glory of housing an international tech giant. The cost? Just several billion dollars in tax incentives and a potential face-lift to the host city. Then last week, in a classic late-episode shock, several news outlets reported that Amazon would split its second headquarters between Crystal City, a suburban neighborhood near Washington, D.C., and Long Island City, in Queens, New York.

If you are among the 11 percent of Americans who believe that everything in Congress is going swimmingly, then save some time and stop reading right now. (But first, please share whatever experimental drugs you are on.) But if you are among the 87 percent of people who are concerned about what is going on in Congress, then I have an important message for you: It’s much worse than you think.

On Tuesday, Congress reconvenes after a month of campaigning. Lame-duck legislation will likely get the most attention, but a more important debate will occur among surviving incumbents and new members in each caucus about how to organize for the next Congress. This debate about rules and process, more than any Russia-related investigation or wall-funding-fueled shutdown, will determine whether Congress can avoid two years of dysfunction or whether it will continue its slide into irrelevance.

President Donald Trump’s decision to brag in a tweet about the size of his “nuclear button” compared with North Korea’s was widely condemned as bellicose and reckless. The comments are also part of a larger pattern of odd and often alarming behavior for a person in the nation’s highest office.

Trump’s grandiosity and impulsivity have made him a constant subject of speculation among those concerned with his mental health. But after more than a year of talking to doctors and researchers about whether and how the cognitive sciences could offer a lens to explain Trump’s behavior, I’ve come to believe there should be a role for professional evaluation beyond speculating from afar.

I’m not alone. Viewers of Trump’s recent speeches have begun noticing minor abnormalities in his movements. In November, he used his free hand to steady a small Fiji bottle as he brought it to his mouth. Onlookers described the movement as “awkward” and made jokes about hand size. Some called out Trump for doing the exact thing he had mocked Senator Marco Rubio for during the presidential primary—conspicuously drinking water during a speech.

President Donald Trump appointed Matthew Whitaker as acting attorney general last week, despite the fact that he cannot legally hold the office. While the president could fix his mistake with any lesser official and in any normal time, the attorney general is no lesser official and this is no normal time. Whitaker takes office during a time of extreme constitutional conflict involving investigations of the president, claims of abuse of law-enforcement and national-security powers, and combat between the executive and legislative branches. In order to prevent a breakdown of federal law enforcement, the White House should hurry to select a permanent attorney general before any more damage is done.

Seven years ago, Park Williams took an hour-long drive with a couple friends to see a wildfire. He remembers it now as a revelation.

At the time, Williams was researching the scraggly pine forests that dot the southwestern United States. He worked at a national laboratory that overlooks more than a million acres of protected desert forest. On June 26, 2011, the wind knocked down an aspen somewhere in that national forest, toppling it into a power line and igniting a small flame. The landscape was parched, the winds were unruly, and soon that flame had become the largest wildfire in New Mexico’s history.

Williams couldn’t go to work—his lab had been evacuated—so he and his friends drove around town, hoping to catch a glimpse of the blaze. Eventually they came to a spot just below the mountains. He remembers the air outside the car reeking like an ancient brick fireplace. The fire stood a mile off. “It looked like a skyline of buildings,” he told me. “You could see it in the mountains above you.”

Clothing brands have been smuggling spandex onto the legs of unsuspecting men.

“I definitely didn’t explicitly understand what I was buying,” Austin Ray, a 36-year-old writer in Atlanta, told me. What he was buying were Gap Soft Wear Jeans in Straight Fit with GapFlex, which is a nine-word phrase to describe a two-word trend: stretch jeans. “Apparently I didn’t think too hard about what those words meant,” he said.

My friend David Covucci, a 34-year-old Brooklyn editor, also didn’t understand exactly what he was getting into when he picked a pair of Banana Republic Rapid Movement Denim jeans off a clearance rack, but the pants immediately felt different to him. “I knew something was up, but I didn’t Google until I got home,” he said.

Influencers are people who have established credibility in a specific realm or industry, and who leverage a social-media following to exert influence and, usually, make money.  Scroll through many of their Instagram feeds, and you’ll begin to notice something: The photos all look vaguely the same. Maybe every image seems washed in pink, or the blues are all the same, or every image is just the right amount of faded. That’s not an accident, or an example of photographic mastery; it’s a preset.

Presets are custom filters applied using Adobe Lightroom, a photo-editing tool. Influencers run all their photos through a specific preset in order to cultivate a specific aesthetic and make their feed look cohesive. Influencers have relied on Lightroom for years, but it wasn’t until June of this year that Adobe finally introduced the ability to create and share presets entirely on mobile, and a preset boom was born.

There came a certain point in George Lucas’s career, as he began writing prequels to his Star Wars films and tinkering with reedited “special editions” of the originals, when he finally lost all grasp on narrative momentum and became a glorified encyclopedia editor. Story took a backseat to explanation, and characters seemed to exist only to be related to future characters in some way. With the release of Fantastic Beasts: The Crimes of Grindelwald, it’s safe to say that the Harry Potter author J. K. Rowling is swerving dangerously close to George Lucas territory.

This is a film that exists primarily to answer questions nobody would have ever thought to ask about a series of books that already told a very complete story. It’s been dressed up as a sequel in the Fantastic Beasts series, starring the squirrelly and introverted Newt Scamander (Eddie Redmayne) and set in the 1920s. But that subtitle, The Crimes of Grindelwald, has all the sizzle of an appendix entry and says everything one might need to know going in. Directed by David Yates, the movie is less a fantasy epic and more a data download, giving out just enough background information to keep fans sated until the next Fantastic Beasts drops in 2020.

Why, exactly, did Donald Trump not join Emmanuel Macron, Angela Merkel, and Justin Trudeau at Saturday’s commemoration of the 100th anniversary of the original Armistice Day? I don’t know, and I don’t think anyone outside the White House does at this point.

What I do know is that one hypothesis that has shown up in many stories about his no-show—that Marine One, the presidential helicopter, “can’t fly” in the rain—doesn’t make sense.

As you’re looking for explanations, you can dismiss this one. Helicopters can fly just fine in the rain, and in conditions way worse than prevailed in Paris on November 10.

Eliot Cohen: Trump fails his rendezvous in France

First, about helicopters and weather. (What follows is based on my having held an instrument rating as an airplane pilot for the past 20 years, and having worked in the Carter-era White House and occasionally having been aboard the Marine One of that era.)
