Historically, watches have had very little information to offer, and essentially zero interaction. It used to be, after a watch was set to the correct time, there was no button pressing, scrolling, or reading to do*, only glances to see the time, each lasting a fraction of a second. With the introduction of Apple Watch this year, there will be a vast increase in the pressing, scrolling, and reading done on watches. To accomodate, people may chose to wear this device differently than their old watches: on the inside of their wrist. Let’s work through the anatomical reasons for this.
Back in November, Richard Burtonstrapped an iPhone to his wrist with a prototype of the Apple Watch’s face displayed on-screen. Doing so made it possible to examine the feel of interactions with the watch ahead of its release. When I say feel, I’m thinking specifically about the way the muscles and joints of our forearms feel as they work in concert to shift a watch face towards our gaze. After testing, Burton noted something interesting about wrist position:
As a result of the twisting strain, I wonder if this might lead to more
people wearing [Apple Watch] on the inside of their wrist.
Let’s look at the bones, muscles, and tendons, the anatomy of this twisting strain.
First, some basics. You can wear a watch on two distinct positions on your wrist: the widespread top-of-wrist position and the far less common inside-of-wrist position. Let’s call top-of-wrist conventional and inside-of-wrist gauche†. When you check the time on a watch worn in the conventional (top-of-wrist) position, you elevate your elbow slightly and then pronate your hand, placing the watch face in a plane normal to your gaze. Conversely, when you wear a watch in the gauche (inside-of-wrist) position, you supinate your hand to bring the watch face into view.
Those links on pronation and supination are not particularly helpful for understanding my point. So, let’s do an exercise: place your entire forearm onto a flat surface (like a table) in front of you, palm down, with your fingers pointing straight ahead. Now, rotate your hand so your knuckles are touching the table and you can see your palm. The anatomical term for what you did when you rotated your hand is supination. You’ll feel some resistance to the rotation, just a little bit of strain in your forearm. If you repeat this palms-up/supination motion with your elbow closer to your side, you’ll notice your biceps (on the front of your upper arm) pulling to supinate your hand. Remember that point about your biceps.
Now, return your hand back to palm-down position. If you go past that postion, rotating your pinky skyward, like you were checking a watch in the conventional (top-of-wrist) position, you’ll notice a little more strain than before. So, if a device is positioned in the conventional or gauche position on your wrist, you’ll need to engage muscles, producing some strain in your forearm, in order to interact with it.
Why are you feeling strain? Explaining that requires an examination of your arm bones: the main bones of the forearm are the radius and ulna, and they slide around one another, not unlike the strands in a rope:
When you supinate your hand (left half of that image), the radius rolls across the ulna and the two become (essentially) parallel. Recall the effort this takes, your arm bones want to return to their original orientation‡. You can imagine this like you are untwisting the strands of the rope—it takes a certain amount of torsional energy to hold a rope in an untwisted position. When you return your palm to the table, the radius and ulna (rope strands) return to their overlapped, unstrained state. It also takes energy to twist rope strands together more tightly — analagous to pronation of the hand.
So if it takes effort to both supinate and pronate your hand, why would one be preferable? Answering this requires seeing some muscles on those bones. First, look at the pronator teres and pronator quadratus muscles below (highlighted in blue), the ones you use when when you pronate to view a watch in the conventional position. Next, look at the supinator (highlighted in green) and biceps bracii (top of second image) muscles, the ones you use when you supinate to view a watch in the gauche position.
Did you notice a difference between the muscles groups used for these opposing actions? The muscles that supinate are far more powerful compared to those that pronate (recall the strain in your biceps when you supinated your hand). This difference in size is mostly due to biceps bracii, which forms most of the front of your upper arm! Big muscles fatigue far more slowly than small ones, all else being equal. So, when you wear a watch in the gauche position, in defiance of convention and at risk of fashion faux pas, you recruit far larger, less fatigue-prone muscles during each interaction. This was of little importance when we used to quickly glance at our wrists, but in preparation for the pressing, scrolling, and reading we’ll be doing, we might consider flipping that watch display to the inside of our wrist.
* If you wound it, you did so when the watch was off your wrist. And yeah, yeah calculator watches.
† We get the word “gauche” from the French, where it means, literally, ‘left’ but the connotation when used in English is something unsophisticated or socially awkward. Something you can do, but in defiance of convention.

Alberta’s Tar Sands and the High Cost of Oil — read this and you’ll feel blinding white-hot rage. Tribal lands, guaranteed for perpetuity, ruined. Sky-high cancer rates. A river made worthless. Wholesale, short-sighted environmental destruction. Half a billion gallons of water polluted daily. A physician trying to alert others to cancers, threatened with the end of his career. Government sitting idly by, interested only in the profits of the tar sands industry. This scar on the land will take hundreds of years to heal, all this damage done for money.
Lili Reitz, executive director of the Ohio State Dental
Board, said last year a quarter of her complaints – or
140 – were against dentists at corporate chains. Yet she
has little authority to take action against the
companies. Instead, her power comes from having control
over the license of individual dentists.
My emphasis above is the entire problem — these corporations chew through young dentists and lean on them to do things that fresh graduates have no idea are poor decisions if your goal is to maintain good relationships with patients for the long term.
“What’s frustrating for us is to go dentist by dentist by
dentist. By the time we get there, they’re not there
anymore” because corporate chains have high turnover
rates.
It is your license that goes on the line when you are pressured to do things by corporate dentistry, and your license that suffers when complaints are brought. These businesses suffer no repercussions; poor feedback doesn’t matter to them since they are high volume, franchised, not structured to work with patients for the long term.
I think corporate dentistry has things to teach small business dentistry: insurance leverage, consistency, and efficiency. But, these good things are meaningless when you see these corporations also lean on huge treatment plans, credit cards, and hard selling: all required to maintain their size and growth.
We were everywhere we could go this Christmas. I was up at 5am on Christmas Eve to go exercise before I worked until noon, at which point I came home to see Essie and Mykala dressed up, Essie’s bottom half looked like a candy cane and Mykala was resplendent* of course. Then it was off to my parent’s for some home-made Dr. Fuhrman lasagna and cookies and presents. Essie opened first, her little hands grabbing each piece of tissue paper. I love to see her touch, feel, grasp things and she has suddenly become so skillful at grabbing everything. The presents were exhausting for her, though, and she needed a nap. This was a theme throughout our presents opening—frequent breaks!
Next, we drove to my grandpa’s to celebrate his birthday, have some of Mykala’s phenomenal Christmas guacamole with pomegranate seeds† and see my mom’s side of the family.
Back into the car, up to Forest Lake, where we saw Mykala’s mom’s side of the family at Mykala’s parent’s house. Essie got to see everyone and was so excited she couldn’t even fall asleep. We popped her into her car seat and she finally slept all the way back down to Woodbury, where we went to St. Ambrose midnight mass with my mom.
Ess was snuggled up in her car seat with her Christmas-colored dog from my parents, “skinny dog”, and she slept through the entire mass. Through all the singing, the readings, the homily, the incense, trumpet-playing, clapping, the entire thing. We went home for some sleep.
Then back at it on Christmas Day! Mykala made me the best cup of coffee I think I’ve ever had‡ and we opened presents from one another. We got Ess one thing: a little, adorable bunny whose tag read “My name is Isabella, please look after me.” We’ve been looking after her.
Then, up to Mykala’s parent’s for mac and cheese paninis and family gifts. Things were going swimmingly until (during one of the breaks in present-opening) I reached for whipped cream, and Essie, perched at my chest in the Baby Björn, employed her rapidly developing skills to grab the edge of a large cup of very dark hot chocolate. I caught the glass, Essie was shaken up but not burned, but the hot chocolate was everywhere. I felt like such a doof. Everything into the laundry, backup clothes on Ess.
Kourtni’s fiancée Arlene then surprised us all with a lovingly crafted and stunning painting of our daughter. So many tears! It was just so unexpected and so different from store-bought gifts to get something we immediately treasured: this hand-crafted visage of our little Essie.
* That’s an excuse to use that work, “resplendent”. I can’t actually pronounce it, so I might as well type it. Plus, it is a good descriptor for how Mykala looked.
† Ok, so, how is it “Christmas” guacamole? Avocados are green, pomegranate seeds are red… and they taste ridiculously great together.
‡ I’ve had some good cups of coffee, but I’ll tell you, the taste is really enhanced when you consume the beverage on your first daughter’s first Christmas morning the day after an exhausting but really without strife, drama, or discord Christmas Eve. Plus, Mykala is great at making coffee.
Thought I worked yesterday, and it turned out I didn’t. Before I figured this out, I drove out to both of the places I normally work, then drove home after a tour of the Twin Cities in the still-dark cloudy morning, and had the privilege of reading Christmas stories to Essie. Next, the three of us went out to pick up a gift, wrapped presents, made salt dough ornaments, took a nap (the three of us! Essie woke up first…), and watched two Christmas movies: The Santa Clause and National Lampoon’s Christmas Vacation.
I was feeling a bit Monday-ish during a lot of the day, and looking back the day after, I wish I’d been cheerier. I have been needing less and less time between an event and the regretting of my missing “experiencing self.” My “remembering self” sees the meaning, the fleeting time, the value of experiences. My experiencing self is mercurial and worried.
However, I don’t think I need to think about all this in an abstract way: I love my wife and my daughter, and I’ll keep trying to love them truer and truer.
Before her nap, I was holding little Essie up at the top of the stairs, and she saw the Christmas tree down below. It’s so fun to see her focus in on something, and to feel her turn all of her attention toward it. Concentrating hard, she began to suck on her hand. She has been an absolute angel this past week—what more could you want for Christmas than a healthy, adorable baby?
This evening, I’ve listened to ten minutes and eight seconds of the new Ben Howard album I Forgot Where We Were and it is spectacular.
We did something today I hope will become a tradition — the Saturday before Christmas (today), we went over to my parent’s house and had some Christmasy time: decorated the tree, had a little lunch together, saw Katy’s new townhome! (it won’t be new every year, but it was part of of the time), just spent some time where no one had to leave or be anywhere. Wonderful. That’s the part I miss about holidays from my youth: uninterrupted stretches of time with family, being over at someone’s house for six, eight hours at a time. I remember during one of these long holidays, probably 1991, I was playing with my new Lego (Technic 8856 “Whirlwind Rescue”), and my grandpa Bup and I were looking at the mechanisms that made the winch work and the rotors tilt. There’s not time for that when you have Christmases on both sides to drive to. So, I hope we can do this Christmas-Time for years to come.
Here’s Essie wearing her mom’s boots at Christmas-Time today:
Mykala just told me a story about changing Ess, which inspires me to record this: I was changing Essie’s diaper a few days ago and she was a little squirmy, so I thought I’d sing her “Silent Night”. I began: “Silent Night,” so far so good “Hol-” *fart*. She only let me get through two words before she vetoed the song. Tried again later in the changing, same result.
I really hate my dental school loans. This is not a feeling that changes when I dig into the twelve different payback models or daily interest tracking spreadsheets I have assembled to assuage my guilt that education loans financially hobbled my family when I thought they’d do the opposite. And really, the hobbling is an emotional feeling as well — not even three years out of school is a poor time to assess the unvarnished facts of an investment in higher education.
It’s what I’ve taken to thinking of as the “earnings floor” that bothers me.
I’ve always lived simply, pursuing few material goods, buying even fewer of them, purchasing for myself two luxuries on a monthly basis: the hosting for this website, and a gym membership. I don’t treat myself with goods or services. My sense of justice, which I guess is some tangle of neurons in my brain nestled near other lizard-like instincts, says that I should be rewarded for my low position on the consumption ladder. And yet, because of these loans, my expenses far exceed my peers. My earnings floor, the minimum I have to earn to make this all work, is very very high, and there is no changing that. So, Mykala and I live the isolation you get from being a minimal consumer (no I don’t want to go shopping, or go to that football game, or drive that far, or see if that movie is any good by paying $20), while also living the stress of unreasonably high expenses. I walk around with a chip on my shoulder, feeling like this:
What I forget to do is punch myself in the face with the Fist of Gratitude. I should be thrilled we can afford the loans! I should be thrilled every single time I post on this website and every single time I get to go exercise at the gym, those are luxuries, right? (Yeah, you just said they were, Alex!) Now, having thought it through as I type, I realize that I hate not the loans but how emotions cloud my judgement about the facts of the loans and about the fine, enviable position Mykala, Essie, and myself are in. I’m a king who imagines himself a beggar!
Franklin: A man down on earth needs our help.
Clarence: Splendid! Is he sick?
Franklin: No, worse. He’s discouraged.
Since it is the Christmas season, you may recognize that exchange from It’s a Wonderful Life, which we watched two nights ago during its annual primetime airing on NBC. The film meant more to me this year than when I’d seen it last. When Jimmy Stewart runs back to the bridge near the end of the movie and yells “I want to live again” he just doesn’t mean it in the sense of he doesn’t want to be a non-extant being who is learning a lesson (that fantastical plot tool is just a faster way to move the story to resolution) no, he means that he wants to feel alive again. You can breathe in and out and test just fine at the doctor’s office, but that is totally uncoupled to whether you feel alive.
I love this photo of Essie. The car seat cover Mykala found and bought for her (which Ess loves, as much as a 4 month old can love anything, and by love I mean she doesn’t mind being put into her car seat at all when this is on it) makes a very nice frame for her face.
