How to get a real education

The Teenage Liberation Handbook

This book is radical. It tries to persuade teenagers to drop out of high school — in order to “get a real life and education” as its subtitle says. This is a dangerous thing to give to your child, because there is a significant correlation between amount of formal education and almost any outcome you care about, including longevity, divorce and poverty rates. Yet informal homeschoolers and unschoolers are outside of that measurement, and by most accounts are doing super. As a college dropout myself, I am sympathetic to alternatives to school.

The purpose of this book is to encourage the teen to make their education their own responsibility. They can remain at school, or as a homeschool take only some classes, or find apprenticeships, volunteer, or even skip directly to college. In short they are designing their own self-education, where ever it may happen. Along the way they develop a better idea of themselves and many more life skills then they would in formal school.

Today as the quality of the average public education declines these ideas are not as extreme as when the book was first written in 1991, but they still aren’t as accepted and common as they should be either.

This is a dense, packed book, overflowing with ideas, tips, anecdotes, cautions, and multiple views — all speaking to the teen and not to parents. It does not lay out a 1, 2, 3 plan. It is messy, challenging. The book itself is probably a pretty good filter for whether the idea of self-education is a match for a young person.

Our son petitioned us to be unschooled, and it turned out that one year when he was 12 was sufficient. It was one of the best years in our lives. Yet in his liberation from school, he discovered what learning “on his own” really meant. It’s challenging. He then choose to go to high school, but with a new attitude that he was in charge of how much and how well he learned. That new found responsibility for his own education made that one year of unschooling totally worthwhile.

There is a whole slew of homeschooling textbooks, advice, and well-crafted tutorials. All directed to parents. This is not one of those. This is a scribbled permission slip giving a teenage permission to consider alternatives for their own education. — KK

• This book is a wild card, a shot in the dark, a hopeful prayer.This book wants you to quit school and do what you love. Yes, I know, that's the weirdest thing you ever heard. Hoping to make this idea feel possible to you, I tell about teenagers who are already living happy lives without school, and I offer lots of ideas and strategies to help you get a real life and convince your adults to cooperate.
  "Excuse me?" you interrupt, "Quit school? Right. And throw away my future and pump gas all my life and get Addicted to Drugs and be totally lost in today's world. Right."
  If you said that, please feel free to march straight to the nearest schoolperson and receive a bushel of gold stars, extra credit points, and proud smiles. You've learned exactly what they taught you. After you get tired of sticking stars to your locker, do please come back and read further.
• Suggest a trial run. you could start unschooling in the middle of August, so they have a couple weeks to see how you manage. Also, that would allow you to recover from the previous school year. You could agree that if they're not satisfied with your way of educating yourself, that you go to school. A drawback to this sort of timing is that you may feel cheated out of your normal summer vacation, and thus not as exhilarated as you would if you quit in, say, October. Also, the whole idea of being watched and evaluated runs contrary to the idea of pursuing interests because you want to. Still, you could probably psyche yourself into it and make it work.
• If you are completely confused as to how to start structuring your life, here's one way: Do "academics" for two hours each day--not necessarily lots of subjects, or the same ones every day. You are not going to dry up in you don't do 45 minutes every day of "social studies." Do some kind of "work" or project for four hours. In your leftover time, read, see friends, talk with mom and pop, make tabouli. Take Saturdays and Sundays off. Sound arbitrary? It is. I made it up, although it is based on a loose sort of "average" of the lives of a hundred unschoolers, mostly college-bound. Once you try this schedule for month, you will know how you want to change it.
• This book has said a lot of nasty things about school. Now it's going to say something nice. Schools have darkrooms, weight rooms, computers, microscopes, balance beams, libraries. They have choirs, bands, track teams, maybe even a Spanish class you want to take. Many enterprising homeschoolers have found ways to use the school resources they want without having to endure everything else.This chapter tells about a few of those ways schools can cooperate with homeschoolers, and gives examples of particular homeschoolers who have taken advantage of school resources. If the schools in your area have never tried anything like this, you can pass this information along to them, and assist them in setting up a program that helps both you and them. Yes, them.

Teach Your Child to Read

This book really works! My daughter could read at age three, and has now really discovered the joy of reading at a young age. There are so many skills that kids can learn for themselves once they master reading. This is truly one of the fundamentals that is worth the effort to instill as early as possible. — James Hom

• The following are the four most important points about an effective sequence forteaching reading:1. The beginning exercises are simple and do not resemble later exercises (just as beginning piano exercises do not look much like advanced ones).2. The program provides teaching for every single skill that the child is expected to use when performing even the simplest reading exercises.3. The exercises change form slowly, and the changes are relatively small, so that the exercises are always relatively easy for the child.4. At every step, the program provides for very clear and unambiguous communication with the child.
• To decode the sentence Ruf unter glop splee, you simply say the words. This illustration points out that you may be able to decode without understanding what the sentence means. Traditional reading programs typically confuse the beginning reader about whether the teacher is trying to teach decoding or understanding. These programs typically begin with the teacher discussing the details of a picture. If the picture shows a girl named Jan, the teacher talks about Jan—what she is wearing, the color or her hair….It might seem that this communication is effective because it promotes interest and gives the children the motivation for both reading and understanding the written message.However, this communication may prompt the child to formulate a serious misconception about how to read. If the teacher always talks about thepicture before reading the word, and if the word is always predictable by referring to the picture, the child may reasonably assume that:- You read words by referring to a picture.- You must understand the word that is to be decoded before you can read it.
• English, clearly, is not a regularly spelled language. It is an amalgam of contributions from Latin, Greek, and French. But there are ways to simplifyit for the beginning reader.Distar solves the problem by introducing an altered orthography. This orthography does two things. It presents variations of some symbols sothat we can create a larger number of words that are spelled regularly (each symbol only having a single sound function). At the same time, the orthography permits us to spell words the way they are spelled in traditional orthography. Here is the Distar alphabet:

Free reading tutorials

Starfall.com

Remember that greeting card company and famous-in-the-late-90s website Blue Mountain Arts? Well the extremely talented and philanthropic founders have started a learningto-read website, totally free, called Starfall.com. My daughters, ages 6 and 7, have literally gotten more educational value out of this than their schools. And now their schools are using it in their classes once a week! Super site, makes the most out of flash and audio on a broadband connection, and really a treasure for young kids (aimed at first graders and below) who want to get going with reading (at no cost).

DIY school curriculum

Home Learning Year by Year

When we homeschooled we were more into unschooling -- ditching a formal curriculum -- rather than replicating a school at home. Still, much learning benefits from structure, progression, and well, a curriculum. You’d like to have a good text book for geometry, or grammar. Or some order to present science concepts. There’s a huge industry selling extensive and expensive curricula to anxious new homeschooling parents. My advice is to get this book and assemble your own.

For each grade from pre-school to high school, the author and novelist Rebecca Rupp outlines reasonable skills and knowledge a pupil could master at that stage for different subjects. Rupp then recommends a refreshingly diverse set of resources for that subject and level, including the best textbooks that work at home, expansive readings around the subject, and even video series when available. You select from her highly curated selections and find the ones suited to your child(ren). In our experience her recommendations and options are excellent. They will likely be on the challenging side, rather than dumbed-down. And unlike many (if not most) homeschooling guides this one is not hampered by a dogmatic religious perspective.

Even if you are not homeschooling, kids learn at home, and this book would serve well to enlarge your child’s formal schooling. This guide supersedes the author’s previously recommended Complete Home Learning Source Book, which is a bit outdated and not as well organized. — KK

• Grade Six: Language Arts
  Read a wide range of age-appropriate fiction and nonfiction materials. Kids should read a mix of classic and contemporary literature, novels and short stories,myths and legends, fables and folktales, poems, plays, essays, magazine articles, and newspapers. Literary experience should be enhanced with a range of supplementary resources, including biographies of writers, audio and video performances, and hands-on and cross-curricular activities.
• At this grade level, kids should learn the techniques of writing an effective multi-paragraph essay: defining a main purpose or thesis, supporting the thesis with evidence and examples, distinguishing unsubstantiated opinion from proven fact, using relevant quotes from attributed sources, and providing a bibliography.They should be able to tailor their writings to a chosen audience or purpose: personal, academic, or business, for example.

PHYSICAL

• Blanket: I don't know why I feel the need to use a blanket everywhere inside my house. I have a different blanket for each chair, couch, or bed in my home, even during the summer. I'm currently typing this while using a blanket on my home office chair.
• When I'm doing an activity that requires focus, I really like to use my headphones. They're Bluetooth ones, and their audio is great.
• I'm addicted to data and statistics; I don't miss an opportunity to generate or read them (especially if there are graphs). That said, I always wear my smartwatch when I'm working out. It tells me if I'm doing well or if I've broken my records. It's really exciting (at least for me).

You can see the Sphere from the air as you fly into Las Vegas. It is a monumental globe wrapped in pixels — a spherical screen. One moment the building is a gigantic eyeball blinking, the next it is morphed into a slowly rotating basket ball thirty stories high, the next it is a crystalline Moon that feels as real as a planet. Part of the Sphere's magic is its scale; it can be seen miles away. Its wizardly transformation from one whimsical appearance to another serves as a billboard. What it is advertising is the Sphere itself. 

The inside of the giant globe is lined with an even finer video screen coated with 25 million tiny pixels. It is the largest hi-res screen in the world. When you stand or sit inside the Sphere’s cavernous cavity, your entire gaze is filled. As you look forward, or up, or to the side, you see images that surround you as clear as day. And since this screen wraps beyond the corners of your peripheral vision, you feel immersed in its fantasy. When the Sphere renders a vista of a desert mountain sunset, you feel as if you are right there in the dust at dusk. In short, the Sphere allows you to experience most of the magic of virtual reality without any goggles or glasses. That naked virtuality is exhilarating. And you experience it communally, with 38,000 other people at the same time. This social dimension makes it both more intimate and more like a spectacle.

Costing $2 billion to build, the Sphere is designed to be a next level venue for rock concerts, cinematic blockbusters way beyond IMAX, theatrical extravaganzas, and mass VR experiences. Besides its mind-blowing graphics, it can also create mind-blowing audio. Using new audio techniques (1,800 speakers) never before unleashed at this scale, every seat in the audience of the Sphere gets a targeted beam of sound tweaked for that seat. This beam of sound is so precise that someone sitting a few seats away could hear something entirely different (say a different language) and there would be no bleeding of sound between them. This precision location accuracy means that the resolution of the sound is as high as the graphics. Every person in the audience receives perfect sound, no matter where they are. It’s like hearing high fidelity stereo audio without earphones. Because you are sitting there without goggles or earphones, yet floating in realism, alongside thousands of others who are also present without visible technology, it feels magical.

Superficially the Sphere is an amped up light show. For decades big rock bands have filled arenas backed with huge displays, and state-of-the-art pyrotechnics. But these huge displays still only fill a small part of your forward vision. The Sphere in contrast, fills the world as far as you can see in any direction. Its architecture is similar to a planetarium; a half dome sits over a raked incline of seats. But the show in a planetarium is projected onto a screen; its images are pale and coarse, while the Sphere’s LEDs emit incredibly brilliant, crisp and luminescent visuals, and in such high resolution that the images appear to resolve in infinity. In addition, the patented sound beams, instead of a wall of sound, add up with the visuals to create an overwhelming impression of realism not found in any other medium.

The Sphere is also more than just an expanded IMAX. The dome screen is so bright that it lights up the entire audience plus anyone on the stage at its center. This stage lends a theatrical element to the venue's strong cinematic nature. When musicians, actors, or presenters gather on the stage, they reveal the Sphere’s true enormous scale, and this also adds to its verisimilitude. The surface of the LED screen is so distant (150 feet) that your eyes are actually focused on far away things, rather than pretending to focus far while actually focused on a nearby screen. Unconsciously, this usual focusing conflict causes stress, while in the Sphere your eye/brain relax and you intuit the distance and scale, which makes the rendered world feel big. The high resolution means the movement of people, vehicles, nature in the distance, which are normally too small to be discerned in detail in most media, are now rendered in the same way you’d see them in real life. I call this singular feature a “distant intimacy,” and this furthers the uncanny realistic atmosphere.

The Sphere’s owners plan to replicate the Sphere many times, like suburban IMAX movie theaters, or stadium arenas. I understand that inclination because I think the Sphere represents a new platform, a new media. It is part cinema, part theater, part VR, part concert stadium, and part Times Square. So far, all this tech has been used to amplify the WOW. It’s really good for playing around with scale, for generating trippy experiences, and grand hallucinations with intense realism. The legendary band U2 launched the venue’s opening evening with a far-out show of psychedelic visions and rock and roll. Clips from the concert spread virally as the show unfolded. Quickly following them a week later, cinematographer Darren Aronofsky will debut the Sphere’s cinematic talents with “Postcards from Earth”. His team developed special cameras to record life semi-spherically in order to maximize the field of vision seen on the inner dome. The shows are spectacular, if not outright spectacles. It remains to be seen whether the Sphere can make people cry, and walk out moved in their souls.

This is just the beginning. The very first movies emphasized the wow factor — locomotives rushing right at the audience. To date one band and one movie director have had a chance to create content for the Sphere. It will take a while to figure out exactly what excels on this new platform. The capabilities of its screens and audio, driven by immense computation, suggest that  the 3D engines powering todays’ video games and VR might be able to create worlds that could be explored in common by an audience in ways that neither solo games, VR, or movies can do. I could imagine new varieties of e-sports taking off in the Sphere.

The Sphere does not work scaled down — that is just VR. Because it needs to be physically big, you will not have one in your bedroom. So you’ll have to travel to somewhere to visit one. It is easy to believe that local movie theaters might be rebuilt as Spheres (at least on the inside) to attract all the people who no longer go to theaters (like me) because their 80-inch screen at home is just as good. The Sphere offers an experience that will be hard to duplicate outside it. A crucial large factor in that experience is its communal nature. The visceral power of tens of thousands of people sharing the same emotions will be worth the price of entry. The more we sit at our desks along all day, the more valuable community entertainment will become. Concert and sports stadiums offer communal emotion, but in a very limited emotional range. The Sphere platform has the opportunity to create content that offers communal emotions that soar in many other directions.

The Sphere is worth going out of your way to experience. In the feverish hysteria during the Sphere’s opening concert someone tweeted, “Late stage empires don’t build things this extraordinary.” I would not go that far, but without a doubt it is a massive technological achievement. It is too early to tell if it will be a marvel like the singular Pantheon, or one of many like Roman colosseums.

New Train Route in North America

It’s been a long time since I’ve seen a headline like that and it actually delivered: usually it means there are plans that might happen a decade from now. But on Friday, the new Brightline train from Orlando Airport to Miami will finally be running for real. It stops at West Palm Beach and Boca Raton too, or you could switch to local service for a stop and get to the Ft. Lauderdale or Miami airports. The next phase, which is still “someday,” will connect Orlando and Tampa. Watch future issues about new lines coming soon in Mexico too, ones the president already rode on for photo ops.

“Laptop Luggers” Profile

A Deloitte report based on a survey conducted in March and April predicted a huge summer for international air travel (they were right) but had some interesting insights on "laptop luggers" who planned to work while they were away. Those bringing a laptop were wealthier (39% making $100K+), more confident about their finances, and planned to take an average of 3.8 trips over the summer. They're not stereotypical loners: "One in four will travel with 3–5 people, while over half of disconnectors are traveling with one other adult." (via Kevin Kelly)

Home Swaps for Working Travelers

Have you ever rented an Airbnb place that promised fast Wi-Fi, only to find you couldn’t get any work done because it was down or super slow? And that you had to work from a bed or sofa? Noad Exchange (an occasional Nomadico advertiser) is trying to change all that with a home exchange program just for working travelers. Every listing must have internet speeds of 20mbps or more and have a place to get work done. Once you join and list your own place, you only pay one credit per night plus the cleaning fee, making it far cheaper than renting through Airbnb or Booking as well. Use ALCENTRO as the promo code to get 3 additional credits when you sign up and if you feel like taking a flyer on an early-stage investment, they’ve got a funding round going too, with low minimums.

Digital Nomad Visa Realities

The hype about digital nomad visas seems to be dying down in the mainstream press as it becomes clear that some of these big announcements aren’t going anywhere anytime soon. Some of the plans that are real have hidden tax implications or onerous paperwork requirements that don’t suit the self-employed. We’ve linked to a few round-up reports in the past, but this seems to be the best one for digital nomad visas you can apply for now and they’re laying out all the cons, not just the pros. Don’t forget that in these other countries that allow long-stay tourist visas, you may not need residency anyway if not moving there permanently.

How PID Controllers Work

https://youtu.be/tFVAaUcOm4I

In your travels in the world of electronics, however casual, you have most likely encountered the term "PID controller." In this Digi-Key video, Shawn offers a crystal clear introduction to what PID (proportional, integral, derivative) is and the science of Control Theory behind it.

In the video, we use an example of a cruise control system in a car. We want to design a mechanism that can maintain a constant speed by controlling the position of the accelerator (gas pedal). PID controllers are a perfect fit for such a system. In fact, most modern cars use PID controllers for cruise control.

A simple, naive approach to designing such a controller is to adjust the process’s input signal based on the set point alone with no feedback. This is known as an “open-loop control system.” This may work in some cases, but most of the time, the output is dependent on other factors (such as road conditions and hill climbs for our cruise control system). As a result, we need to incorporate feedback into our controller.

A “closed-loop control system” measures the actual output of the process and compares it to the set point. The error is the difference between these two values, and it’s used as the input to the controller. The controller looks at that error and makes adjustments as needed to the process’s input.

Scissor Sharpening Basics

https://youtu.be/6yQp7WYP-E4

Confession time: I absolutely suck at tool maintenance. I avoid it like the plague. Every year, I tell myself that I want to get better, and every year, little changes. At least this year I told myself I would be better about cleaning the gardening/yard tools and have done OK with that. Part of this maintenance aversion means that I never sharpen anything. But, after watching this video, I decided to at least sharpen our scissors collection. In the video, James uses a cheap flat file and a diamond sharpening/whetstone to get the job done. Like James in the video, I have several pairs of lovely vintage scissors that need this kind of TLC. After the scissor sharpening, it should be on to the knives. Our kitchen knives are laughably dull. Do you share a similar aversion to sharpening and other forms of maintenance?

Looking at Hobby Brushes under a Microscope

https://youtu.be/Wwx0duuq_hc

In this Goobertown Hobbies video, Brent delves into some hobby science with his new digital microscope. Using it, he peers into a bunch of synthetic and natural bristle paint brushes, from the very cheap to the expensive, from the new to the very well used. The results are fascinating. Under the microscope, you can really see why natural bristle brushes are superior to synthetics, how the tension in their fibers helps in keeping the integrated, pointy shape of the brush. One of my favorite parts of the video was seeing his dirty old brushes under the scope before and after a thorough cleaning.

TOYS! Magnetic Project Mat

Via a Cool Tools “Tools of Possibility” newsletter, I was reminded of this wonderfully useful iFixIt magnetic parts mat for assembly/disassembly of electronics. Not only is it magnetized to keep all of your parts in place, it’s also a whiteboard so you can label everything and even take notes. You can also get one for half the price on Amazon.

Revisiting “The Kenny Rogers Rule”

In having done this newsletter for the past 5 years or so, I am frequently asked what are my top-most tips? What are the ones that stick, that “changed my life” (or at least my workflow). I was reminded a few nights ago of one tip that would be at the top of such a list: The Kenny Rogers Rule (as in “You've got to know when to hold 'em, Know when to fold 'em, Know when to walk away, Know when to run”). This is a name I came up with years ago for knowing when to take a break from a project that has turned to little but frustration. The other night, I was trying to put together a bed frame that was not cooperating. It was all the things we know all too well about modern flat-pack furniture: warpage, improperly-drilled holes, cheap hardware, confusing instructions. By the time I was down to the last two nuts and bolts, I was struggling, sweating profusely, and rung tight with curses and frustration. I decided to put the tools down and come back tomorrow. In the morning, rested and with a new dedication to getting this damn thing done, it took about ten minutes to finish (with nary a bead of sweat or profane utterance). A perennial lesson from Kenny to us all.

Shop Talk

It’s always interesting to see which posts are going to get the most response. It turns out (OK, no surprise, really) that everyone loves pasta and has something to say about it. I got the biggest response ever to the item I posted in the last issue about cooking spaghetti right in the sauce instead of in water.

Just a few examples:

Steven Roberts: Yes on the pasta in sauce... been doing this for years, both with fresh pasta from my extruder and dried stuff. Originally motivated by being on the sailboat and wanting to minimize fuel, steam generation, and water waste... but I came to like the effect of cooking something in flavor so it's not just a neutral substrate. Coupled with making pasta that contains herbs, it's another variable to play with that has a side benefit of resource management... but so much with creamier sauces unless you do the wine part first then add heavy cream near the end. I never turned it into a formula, but when I do that I just make the sauce more watery than usual, then adapt on the fly if I underestimated. (For some things, that differentiation between substrate and sauce has greater expressive value, and the equation is more about fuel and water resources. It's more of an addition to the toolkit than a standard protocol.)

Daniel Kim: It turns out that you can soak pasta in cold water to make it pliable. This can be stored in a bag in the refrigerator, and then put in to the sauce when you heat it up. (When I've tried cooking pasta in sauce, and have leftovers, the pasta gets too soft for me)

Amit Agrawal: Also, this trick thickens the pasta sauce from the starch in the pasta.

George Mokray: I save pasta water for other uses later.

P. Korm: Cooking the pasta in the sauce is a trick that Ralphy shows Jackie Jr. in season 3 of The Sopranos. Though, of course, it's not tomato sauce, it's "the gravy'.”

Matt Middleton: If you have a standalone pressure cooker (e.g. Instant Pot), you can do the same thing; you need about 16 oz of sauce, 16 oz of liquid (water, broth, wine, etc.), and 16 oz of pasta. Meatballs are optional, but recommended IMO; if using, add them first. Break long noodles and spread out so they don't clump too much, then dump sauce and liquid over everything. Set it for high pressure, and cooking time is about half whatever the box says; the linguine I usually use says 9 minutes, so I round down to 4. Quick release the pressure, and if yours has a Keep Warm setting, turn it off. When safe, open and use tongs to stir up the noodles. They might seem a little underdone, but that'll fix itself up quickly enough. My kiddos prefer the frozen box meatballs, so I use those, but you can class it up with your own fresh ones, saute onions & garlic before adding sauce, or any other technique you like to build up some extra flavor.

Get Don't Feed the Monkey Mind

Don't Feed the Monkey Mind: How to Stop the Cycle of Anxiety, Fear, and Worry by Jennifer Shannon, explains that anxiety is generated by the "monkey mind," which perceives threats and sounds alarms to try to keep us safe. This can lead to an ongoing "anxiety cycle" where we feed the monkey mind by using avoidance and resistance strategies in response to anxiety, which confirms the perception of threat and maintains the anxiety.

The book identifies three common "monkey mindsets" that underlie anxiety:

1. Intolerance of uncertainty: Believing we must be 100% certain of outcomes.
2. Perfectionism: Believing we cannot make mistakes.
3. Over-responsibility: Believing we are responsible for others' feelings.

To break the anxiety cycle, Shannon recommends replacing avoidance/resistance strategies with strategies that create new experiences to support an expanded mindset. She also encourages welcoming anxiety sensations and emotions rather than resisting them.

Here are four tips from the book:

Thank the monkey

When you get caught up in anxious, worrying thoughts, don't try to suppress or argue with them. Instead, just observe the thoughts and say "Thank you, monkey" to acknowledge them. This creates distance between you and the anxious thoughts.

Ask the monkey for more

When you feel anxious sensations or emotions, purposefully ask for more of them. Say things like, "Good, let me feel more numbness!" This shows your brain that you can handle the feelings.

Ignore the monkey

Practice making decisions according to your values rather than the monkey mind's focus on safety. For example, choosing an adventurous restaurant over your usual safe choice.

Befriend the monkey

Treat the monkey mind like an overprotective friend trying to keep you safe, rather than an enemy. Have compassion for its limited perspective.

Understanding big buildings

David Macaulay’s Visualizations

Few have mastered the big picture better than artist David Macaulay. When a kid wants to know about pyramids or castles introduce him/her to Macaulay’s books. Macaulay dissects the parts in kid-obsessive detail while keeping his eye on the whole. And he shows how it all grows in time. His uncanny ability to x-ray complex places makes him the master guide to the built world. Of all his books, Underground is his most revelatory. Even adults will find themselves studying each page of “the city underneath the city” in aha enlightenment. Oh, so THAT’S how it works! Macaulay revisited three of his early books — Castle, Cathedral, and Mosque — creating new even more amazing visualizations, and combined the books into one new book called Built to Last. It’s a short course on civilization for kids. — KK

No-metal Belt for Airports

Co-founder Kevin Kelly and I both swear by no-metal belts for airport days and we also like the fact that these military-style webbed ones don't have holes either, so they fit precisely no matter what's going on with your waistline. I've been using the same one for five years and it looks like new. There's a stream of very similar ones on Amazon with Chinese names, but this brand has the highest ratings and you get two (of different colors) for under $20, with Prime shipping.

Tough Solar-powered Watch

Speaking of travel gear that holds up well, I've passed the 12-year mark on the watch I wear the most when traveling: My Casio solar-powered one with an altimeter. I've never replaced the battery because it recharges from sunlight. Even when it sits in a drawer for months though, it doesn't wear down because the display turns off to save power. Prices range from $35 to $350 and that vast range stems from how deep they can go in the water and what features they have, so if you don't care about underwater strength, the altimeter, or other features, then you can go with the low end at this page. Some have analog dials too.

The Return To Office Tug-of-war

Corporate efforts to get people to commute to cubicles again are not going well. Widespread employee satisfaction drops in surveys seem to be correlating closely with back-to-office demands. When dating app Grindr demanded that its workers return to the office, almost half of them said, "No thanks" and quit. At Amazon, efforts to drive workers back to the office have become a PR nightmare for the company and led to very public departures and protests. Meanwhile, remote companies are finding higher worker satisfaction, less turnover, and more diversity in their workforce. Remote work is a godsend for those who are trying to balance work demands with taking care of the kids, so why are "pro-family" leaders so hung up on butts in office seats? I believe the most obvious explanation is the most plausible: roughly half of commercial office space is sitting empty and a lot of powerful people own those buildings—or collect taxes from them.

Earth-friendly Toiletries in Europe

We tend to be North America-centric in this newsletter since that's where we and the biggest chunk of our readers are from, but here's one for the Europeans. Reader Mira replied to my earlier post about planet-friendly toiletry packaging with a recommendation for a Dutch company called Lekker. They make organic, sustainably packaged items like deodorant, lip balm, sunscreen, and soap. They ship all over Europe and in the Netherlands shipping is free with a minimum 35-euro spend.
