When Hunter turns 18

As baby Hunter nears his first birthday, I have been wondering what the world will look like when he’s 18, in 2033.  Here are my predictions — or really punts — enjoy!

  1. He won’t use cash, ever.  He may, though,  have a ‘cash collection’, the same way I used to have a stamp collection.
  2. Neither he nor his friends will have a drivers’ license. He will either use public transit, bikes, taxis, or self-driving cars.
  3. Neither he nor anyone he knows will smoke cigarettes. There will be fewer cigarettes sold than marijuana joints in the western world.
  4. He will not have any passwords. All his access will be fingerprints or facial recognition.
  5. He won’t need a passport, or any ID.
  6. He will be as practiced in making music and videos as we were in writing essays.  And he’ll use them to express his ideas, both academically, extra-curricularly and socially.
  7. He will apply to university by providing the school a database with every homework assignment, test result, school newspaper blog entry, social media post and music video he’s done. The universities will then run their artificial intelligence algorithm to build a class that optimizes for cultural fit, future potential and diversity.
  8. Flights will be three times as expensive as they are now, and he will travel half as much.
  9. Meat will be three times as expensive as it is now. He will use it as garnish rather than a main part of a meal.
  10. Streets will be quieter, with more public transportation and electric vehicles.
  11. He and all his friends will speak Chinese.
  12. He won’t be able to board an airplane if he’s sick, to stop the spread of some global pandemic. Health scans will replace security scans at the airport.
  13. He will feel safe from crime, as police departments are given more powers and technologies to prevent criminal activity.
  14. He will fear the government, though, which will have expanded its powers to combat an ever more vague definition of terrorism. He will find himself self-censoring what he says online to avoid seeming anti-establishment in the years before applying to university.
  15. 90% of what he learns in school will be fascinating to him, and stick with him. He will be an agent in his own learning, actively exploring topics, pursuing his interests, and connecting with others inside and outside his school that share his joy of learning. His daily curriculum will not be History, English, Math, etc., but some cross-disciplinary, immersive, skills-focused new thing I can’t even imagine.
  16. He will assume almost everything is knowable. Instantly.
  17. He will be addicted to getting the latest information about everything from politics to fashion to friends, and be 100x better at quick analysis than deep analysis.
  18. He will get his grocery deliveries by drone.
  19. Half his friends will live with their parents when they start working; the other half will sleep on lofted beds to save space. He and his 3 friends will live in a 600 square foot flat and pay over 50% of their income doing so. Owning a home in London will be reserved as a ‘post-IPO’ fantasy.
  20. He will not apply for his first job; his employer will select him based on the online reputation he has built for himself in that field.

And things that won’t have changed:

  1. He will be tired and stretched too thin from all the academic, social and extra curricular things he wants to do.
  2. He will celebrate his 18th birthday with a cake, candle and the Happy Birthday song.
  3. He will still get the common cold.  Tylenol/paracetamol and a cup of tea will still be the main treatment.
  4. He will still wear jeans on the weekends, and a button down shirt to important meetings.
  5. He will still develop a crush on the popular girl. And though he makes her the subject of his music videos, she will not know he exists.
  6. And of course, when his first love breaks his heart, or he runs out of money, or fights over dishes in the sink with his flatmates, he will always be welcome home to mom and dad.
Best

On Binaryism

Before having baby Hunter, I would subconsciously score each experience on a graduated scale from 0 to 100.  A dinner out would get maximum points for great conversation, food and ambiance. A walk through a park would get bonus points for having roses in bloom and the sun streaming through poofy white clouds.

But now, I score my life on a binary scale : 0 or 1. Did I go to dinner or the park, or not?
The other day, I was two hours late to dinner with some friends, as my 8 month old baby wasn’t settling easily down to bed. The food was good but not mind blowing, and some people couldn’t make it.  But instead I just thought : I made it out to dinner! Check!  1 point!
For someone who cared a great deal about the difference between an A and an A minus as a student, it feels counter-intuitive that this ‘pass/fail’ system would be so rewarding, and so liberating.
But it is.
And it takes so much of the pressure off of being a new parent.
Take ‘baby cinema’ as an example. On a Monday at 11 am, parents and their babies go to a theatre to watch a movie. Pre-baby Hunter, I might score the experience as less than half as good as seeing a movie without the baby. After all, I missed the beginning waiting for the baby to wake from his nap, the key moment while I was in the bathroom changing his nappy, half the dialogue thanks to the other 30 babies crying and half the plot due to my own sleep deprivation.
But under binary thinking, I thought : who hooo!  I made it to a movie!
Binary thinking is essentially a shortcut for optimism: seeing the glass as half full, rounding up.  And it’s made me appreciate much more of the past 8 months of maternity leave.
I admit, it’s a strange time to become a “binaryist”. The internet has made micro-optimization ever easier, whether it’s planning your route, finding a phone plan, or meeting new people. My generation, and especially the ones after mine, will come to expect everything to be optimal, always.
So perhaps then it’s the right time.  As despite the advances in technology and civilization, not everything is always as good as you might have hoped. Binaryism gives us an easy way to handle times when it isn’t.  And to enjoy each experience for what it is : itself.
Best,
Liz

On becoming a mother

It hit me that I am now a mom the way that rain drops make you wet : one drop at a time. Our son, Hunter Aab Henriksen was born Thu Dec 3rd at 10:20am, 3.62 kg (8 lbs), without complications at University College Hospital in London. My husband Oyvind and I are very much in love with the little man.

The slow process of becoming a ‘mom’ started when I found out that I was pregnant. It got a little more real after our 12 week ultrasound when we saw the bambino for the first time, dancing to each heart beat. It got more real still when I started telling people I was pregnant, and as my bump became visible. Even feeling him kick was gradual — was that a kick or just gas? At 20 weeks we saw on the scan that he was a boy, and it hit me a little harder : we weren’t giving birth to a baby, but to a person, a boy who one day would go through puberty and become a man.

By the last two months, as I sported my ‘Baby on board’ pin to get much needed seats on the Tube and bus, I was very ready to be a mom. Or at least to not be pregnant anymore!

Then came the big day. I’ve heard some women say they feel an instant surge of relief or joy the moment their baby is born. For me, it took a few days. The first few hours in the hospital, I was just too physically spent to really process anything. Having just had nearly three days and sleepless nights of contractions and 9 hours of labor, my new mom thought process was more like, ‘what on earth just happened?’

When Oyvind and I were alone with our son for the first time in the hospital recovery room, it started to sink in. And there was a moment, when little Hunter looked up at me for the first time. He’s so cool.

So drop by drop it has become more real these past 5 weeks, as the exhaustion and aches of labor have faded, and a new routine of being a parent begins. It will continue to dawn on me that I’m a mother now, little by little : each time I fill out ‘mother’ on a form, or see my parents sing their grandson ‘rockaby baby on the tree’ the same way I was sung to.

5 weeks down in learning to become a mom. The rest of my life to go.

Yours,
Liz

On married hugs

My dear friend Jo asked me to prepare a blessing for her wedding this past weekend, about something important in a marriage. Here it is (insert a perfect New Hampshire mountain backdrop and a perfect couple!):

On the blessing of married hugs

Jo, Scott, You will have many blessings in your marriage. One of the best is married hugs.

Hugs are the best.  There is no easier or more effective way to love and to feel loved than a hug, both in times of celebration and in rough times.

While the kiss is the highlight of the wedding, the hug is the highlight of marriage.

What is a married hug? The word, hug, comes from the Norwegian word hugga, meaning to comfort. So it’s something comforting. And something about holding someone in your arms.

There are many types of married hugs:

  • The casual ‘just got home’ hug;
  • The ‘bone crushing’ squeeze hug;
  • The ‘Netflix on the sofa’ hug;
  • Various private hugs; and
  • Various public hugs, including one you’ll use today called the ‘don’t mess up my hair’ hug;
  • And perhaps one day the awkward but awesome ‘pregnant hug’,
  • Which prepares you for the inevitable future ‘beer belly’ hug.

Of course, you’ve hugged and been hugged since the day you were born. So what’s new and so special about married hugs?

Starting today, you are now each others’ go-to hugger, more than any other relationship you’ve had. You’ve both lived and traveled far from family and friends. But while you will still spend time apart from each other, your marriage will feel most complete when you are back in hug radius.

And for those times you are apart, look at your hands, at the wedding rings you are exchanging today. There are many things that a wedding ring symbolizes, of course, but I like to think they symbolize a permanent hug.

Jo, Scott, may you enjoy the many blessings of married hugs, as you promise to not just have — but to have and to hold — each other from this day forth.

On love

One of the best parts of being engaged is getting to gush about how in love you are. So with less than two weeks to go before we get married, I figured I’d share some of my favorite things about my relationship with my fiance Øyvind Henriksen.

(1) Saying thank you.

It’s probably the thing I like most : Øyvind and I say thank you all the time. Even for expected everyday things, like making breakfast, paying for dinner, taking out the trash, buying groceries, or washing the dishes, we both say (actually say) thank you.

Looking for opportunities to say thank you makes me notice more when he does something nice; it becomes clear just how many warm, generous things Øyvind does everyday. Saying thank you also feels good, like making a donation to a cause you believe in. And getting a thank you feels great, like your work is appreciated. Thanks Øyvind!

(2) Accepting offers.

In the theater art of Improvisation, there’s a concept of “accepting all offers” : if a fellow actor turns to you to say “Hello Doctor!” you should then step into the role of a doctor (e.g. “How’s your headache now?”) rather than blocking the offer (e.g. “No, I’m not a doctor”). Accepting an offer allows the scene to build on itself, and go to interesting places (“My head is terrible! I wish you would just cut it off!”… “Ok, let’s go to the guillotine!”). Blocking results in tension between the players, and a scene that’s dead in the water (“uh, sorry, uh.”).

Øyvind and I have had great adventures together these past three and half years thanks to his tremendous openness to new experiences and ideas. His willingness to “go with it” comes out in our conversations, leading to the creation of the famous “zeppapult” (a combination of zeppelin and catapult to solve urban transport problems, of course); in his incredible success in envisioning, launching and leading his mobile app tech startup Poq Studio; in his eagerness to try new restaurants, travel destinations, and fashions; and his genuine interest in people from all walks of life.

So when he offered his hand in marriage, it was easy to accept!

(3) Acting out of love, not rights or power.

In Negotiations class in business school, we learned that there are three levels of negotiations: those based on incentives, rights or power. Basing everyday interactions on incentives is the best, as it allows you to find the best outcome for all parties — I don’t have to lug the smelly trash down four flights of stairs, and Øyvind doesn’t have to wear rubber gloves and scrub frying pans.

But once you start going into the second level of “negotiations” — relying on the concept of rights — it quickly becomes messy. “Rights” based negotiations are those that focus on equity, laws, justice: “I did 10 minutes of housework there it’s only right that you do 10 minutes of housework”. Once there, you quickly break down further into power negotiations which are usually quite unhappy : “you can’t make me take out the trash!”.

Thanks to this framework, I no longer keep a tally of what I’ve contributed to our household or relationship and compare it what Øyvind has done : it just doesn’t matter. Instead, we both try to do what we can to make the other person happy. The result? We both do lots of things that make the other person happy.

(4) Having read Mens are from Mars, Women are from Venus.

Yes, I rolled my eyes too. But it opened my eyes to false assumptions I was making about the opposite sex. For instance :

  • Points: Men and women calculate “points” differently : men assume that if they do something really romantic they earn 50 points and then can take the next two weeks off; women give men 1 point for everything they do, regardless of how big or small, and want their man earning a point a day.
  • Cave time: Men need some cave time, alone (or with a PlayStation), regardless of how much they love their partner.
  • Probing: When women are sad or need help, they want someone to notice and start probing to find out what’s wrong. Men, however, want to retreat into their cave. They can see caring questions like “what’s wrong honey” as undermining their manly competence to deal with their own problems. When they want help, they’ll ask.
  • Will v Can: Men don’t like being asked “can you take out the trash” and prefer “will you take out the trash,” as it gives them the option to say no, and doesn’t challenge their competence. I had thought that “will” and “can” sounded the same, until the author pointed out that “will you marry me?” has a very different tone from “can you marry me?” :)

(5) Never taking anything too seriously.

My 99 year old aunt, when asked what contributed to her longevity, said : “never taking anything too seriously.” I love Øyvind’s playfulness, and often feel like I’m on a really great playdate from the happiest days of my childhood. His office (and our home) is decked with cute things, and he doesn’t shirk silliness — just ask his little nephews who love ‘Onkel Monster’ very much.

(6) Being really similar.

We like the same things : picnics in the park, exploring new places, drinking black Americanos, dancing, doing challenging but fascinating jobs, going out for dinners and date nights, and having friends over for dinner parties.

If you had told me that a girl from Manhattan would meet a guy from a 50,000-person town north of arctic circle, and that we’d be so similar, I’d never have believed you. And if you had told me that my next language after Chinese would be Norwegian — a language spoken by less than 5 million people who also speak excellent English — I’d have laughed. Jeg ler ikke nå.

So maybe I also should write to future Liz and Øyvind as well : may you continue to accept all offers, do things out of love rather than justice or power, share interests, and not take anything too seriously. And if this Aabservation proves helpful during the tough times of your marriage in the many years to come, you can thank me.

Happily yours
Liz

Blob people and Line people

It started, like this note, with a blob. A canary yellow smudge of paint in the middle of the white canvas pallet. A few more strokes of the instructor’s brush, and two circles emerged, one balancing precariously on top of the other… But what is it?, my 7 year old self wondered. After another few strokes, suddenly it was clear:  the yellow head and body of a baby chicken. When the instructor then drew a dark black line around the bird, my life was changed forever: until then, I never knew you could paint by filling in the middle before drawing the lines.

There are two types of people: blob people and line people.  Blob people explore life like the yellow canary painting: putting color down first, and seeing what emerges. They wander across the pages of their lives, and when they find something shiny, stop, and let the ink in their pen saturate that part of their story. You know them: the guys who picked their major in college based on what department they happened to have the most courses in.  Or that friend who moved to a foreign country because they were curious. If you ask them to identify a good investment, they’ll probably cock their heads to a side, remember a cool article and exhibit they saw about 3D printing, and suggest looking there.

Line people, by contrast, are the planners, who draw the black line first, and then fill the rest in according to their outline. They have their act together. Line people figure the exact combination of courses and hours they need to get into medical schools, or how to hit all of Rome’s best tourist spots in 12 hours. Ask them to identify a good investment, and they’ll structure you a spreadsheet of recommendations, with weightings for risk appetite and investment horizon. You know them too.

A mix of these personalities can achieve incredible (and fun) things. And indeed, many people that have defined history are blob people who figured out how to draw a line around what they were working on:  the men that drafted the sentiments of the rebellious colonies into the US Constitution; business leaders who took intuition about market trends built railroads; religious prophets that used memorable parables to define good and evil in ways that resonated across the world for centuries; scientists who captured observed curiosities in universe in simple equations; writers who defined the subtle sensations of the human experience in words that affect how we see the world ourselves.

To finish this Aabservation, I suppose I should draw a final clear black line around the idea that emerged over the past paragraphs.  Namely, this post postulated personalities of three types of people: (a) Blob people, (b) Line people, and (c) Blob people who draw lines.

Pigeons

Pigeons are stunning creatures.

Trust me. I also once thought pigeons were vermin: dirty, stupid rats with wings. No longer.

The turning point for me came at Everest Base Camp. I had schlepped there from Lhasa, Tibet: three days of off-road driving at increasing altitudes. When I arrived at the (bottom of the) top of the world, there they were. How could my city-slicker birds also survive in the Himalayan heights?

The more I looked into pigeons, the more incredible these birds became. Pigeons are a type of dove whose native home is a rocky cliff, which is why they feel so comfortable in Manhattan window sills.

They are by some accounts the smartest bird in the world, able to recognize themselves in the mirror and even recognize letters.

They are homing birds, instinctively able to return home from anywhere — and at up to 100 miles per hour for many hours on end. There’s a culture of racing these birds by putting them into an enclosed van, and releasing them hundreds of miles from their homes. Scientists suspect magnetic elements in their nose and their exceptional eye sight lets them find their way home, even over oceans. Their eye sight works better when their eyes are stationary which is why they try to hold their heads in the same place when they walk.

This homing ability earned them war medals. During World War I, there were thousands of pigeon handlers, who managed communications with the front lines by tying messages to pigeons’ feet and letting them fly home. Some pigeons heroically flew through mortar fire to get the message home and safe their human comrades.

This homing ability is probably why we see pigeons everywhere; mankind’s armies have been using pigeons as carrier birds for thousands of years, and so they have become as domesticated as dogs, horses and cats. They’ve adapted to eat our food, ignore our crowds and cars, and find homes in our buildings (and on our statutes).

And they even resemble us socially. Like humans, they tend to mate for life. That pigeon couple you pass on your way to Starbucks has likely been together for years, having made a home in a window near you.

Watch the younger ones in a park while listening to club music on your headsets, and you’ll see more social similarities: the males puff up and dance in circles while the lady in question will look demur and continue to peck at the ground. If a person throws out a handful of pizza crusts nearby, the guy will interrupt his wooing to get some grub. (Typical.)

Pigeons even kiss. The first time I saw it happen was, ironically, on the death wall of the Sagrada Familia cathedral in Barcelona. They smooched for a minute, he popped up on the back of her to do his thing, then jumped off just as fast, fluffed his feathers, and flew off.

And of course, pigeons also poo on things. So, the last few decades, we’ve come to think of them as stupid.

But watch them more closely, and admire them: their intimate human-like relationships, their intimate relations with humans, their incredible adaptability, and their strength, endurance, intelligence, and skill. Perhaps you’ll come to see, as I did in the thin air of Everest, how beautiful ordinary life becomes when you find pigeons beautiful.

Yours,
Liz

Yes, there’s a book about pigeons. And yes, it’s good. And, yes, of course I read it.

The Myth of Value

One of the greatest misconceptions I had before my MBA was thinking that things had value.

I had this idea that a thing, whether it was a company, a product or a service, had a value, and that getting an MBA would teach me out how to calculate that value.

But what I’ve learned over the past two years is that things don’t have an intrinsic value based on just what they are, but also on the 5 other “Ws”: who, when, where, how and why they are being valued. If you want to find the “value” of something, you need to ask 6 questions:

- Who is doing the valuing? You might call this defining or segmenting the market. To increase the value of something, find the people who value it most — who really hate being cramped on flights and can pay for business class, or who love watching Olympic volleyball.

- When are they doing the valuing? In other words, what else has just happened to them? Maybe they are entrepreneurs who are about to go bust; they may value cash enough to give up more equity than they would otherwise. Or maybe they are on a first date, and happy to splurge on champagne. Or just lost their life savings in the financial crisis. Timing matters.

- Where are they when they are valuing it? You might pay $15 for a gin & tonic at a posh club, but would balk at paying that in a dive bar. “Where” is relevant to real estate, as anyone renting a flat in London knows all too well, and anything that relates to real estate. Which used to be almost everything, before the internet anyway. (And now with mobile browsing location detection, the “where” is making a comeback.)

- How are they valuing it? People value most things in reference to other things, so understanding what someone is using as a comparison matters: are they comparing the price of the Gucci wallet to cheaper wallets, or to other more expensive items at Gucci? Are they valuing a company based on its assets today, or on its potential future cash flows in 5 years?

- Why are they valuing it? Buying a white cake costs $20. Buying a white cake for a wedding costs $200. People will value the same thing in radically different ways depending on the reasons for valuing it. Valuation by brokers can be particularly tricky for this reason: are they pricing the house low to get it sold, or high to increase their commissions?

- What are they valuing? Oh yeah, the thing itself matters too. A little.

Well, Liz, you think, what an obvious Aabservation. Of course the value of something depends on who, when, where, how, and why as well. Of course it’s not just the “what.”

But I promise you’ll forget that complexity as soon as you see a statistic about the value of Greek debt (“the” value? really?), or observe price volatility in the stock markets (surprise!), or see a supply and demand curve showing a thing’s value at the intersection.

If you are interested this topic, I’m happy to chat further as we learned a number of techniques to get at the value for a specific transaction throughout our MBA — in marketing, financial modeling, negotiations, and organizational behavior classes.

But that would take longer to explain here, and your time, by any metric, is valuable.

Yours,
Liz

Ode to an Onion

As part of my friend Silvia Chiang’s wedding last week, I was asked to prepare a short talk on the topic of “Humility.” Thought you might have fun with this. Congratulations to Silvia and Parker!

On humility
Ode to an Onion

Oh onion, humble onion –
How modest you are. You never seek attention, growing underground, dressed in brown.
Then, when peeled and brought to light, you hide in white.
So that you stay overlooked, when cooked, you turn clear:
You disappear.

But onion, humble onion –
It’s not this modest humility which awes.
It’s how humbly you serve, enhancing everything around you, adapting yourself in a thousand ways.
Diced or sliced, you turn bland salads into spicy fests of flavor.
Or sauteed with ginger chicken, you melt into caramel, sweet and tender.

For onion, humble onion –
What recipe do you not humbly grace?
Sauces, stews, salads, sandwiches, stir fry, shish kebab,
Meats, marinades, curries — cuisines of all types, from so many cultures.
You unite us all in flavor.

So onion, humble onion –
Though it’s not your nature, accept this song of praise.
And remind us, next time we see you, hidden on our plates, to be like you :
As humble as an onion.

- Liz Aab

Why Nerds Wear Glasses

Why, really, do nerds wear glasses? As a nearsighted nerd myself, I’d often heard the usual reasoning: reading strains your eyes. But surely non-nerds strain their eyes too, don’t they? Like by looking at screens like this one?

I think the causality is wrong: it’s not nerdism that causes bad vision; it’s bad vision that creates nerds.

I observed this phenomenon a year and half ago, at the start of my MBA at London Business School. I sat in the back of the U-shaped 80-person lecture theatre (yes, with an “re”). When our first lecturer projected an Excel spreadsheet on the whiteboard, I had to move closer to the front — I couldn’t see the microscopic print from far away. The past year and a half, I’ve asked to sit in the front 2 rows for all my classes, so that I don’t have a problem seeing the board clearly.

Now, what happens when you sit close to the front? You speak more often and with less inhibition, because you literally don’t see the 70 other students behind you in the class. You don’t have to shout across a long distance, so you see education more like a conversation more than a speech. You can’t get distracted by your iPhone, because the professor will definitely catch you. And so day after day, you are more engaged in the class than your peers in the back row, you pay more attention, you ask more questions… You are a nerd!

Remember back to where this all started, to when you got your very first pair of blue plastic glasses. Your vision had been squinty just before you saw the eye doctor, so your 10 year old self inched closer to the chalkboard. Once there, the teacher called on you more, you asked more questions, you talked less with your neighbors, you doodled less with your crayons… You became a nerd!

By the time your vision was corrected (and it had to get corrected each year as your eyeballs grew, remember), your position at the front of the classroom, and in your class, was set. You would always be a nerd.

If you did a study comparing the distance students are from the whiteboard with their academic performance, I’d bet you’d get statistically significant correlations. And if you extended this study to see how people did in life after school, I suspect you’d get lasting effects.

If my theory is right, then it might be worth seeing what happens if schools have no “front” or “back” of the classroom. If all 4 walls had chalkboards on them and our seats swiveled around, everyone would have some time when they were equally close to the board. Would everyone become a nerd, or no one at all?

It’s an interesting topic, and something I thought you might be interested in looking at closer. Assuming, of course, you are a nerd.

Yours,
Liz

Walk This Way

If you want to dictate someones character, buy their shoes.

No, this Aabservation isnt about how shoes look its about how shoes feel. Sure, a shoes appearance sends a message about the wearers social group and personality. But a deeper reason, I think, is that shoes physically affect how we walk. And how we walk affects our mood.

Two weeks ago (wearing slightly heeled boots), I power walked around New York City. Id arrive each place somewhat breathless from walking briskly, my brain whirling with the increased blood flow. One such whirling thought was this: could the citys energy stem from the fact that its residents literally have to run around it, and therefore end up at each meeting physically energized?

As I got my breath back, I watched closely how people walked. Amazingly, peoples shoes were completely affecting their gait. Next time youre outside, try it yourself: watch people walking down the street, but dont look at their shoes. Then, just by their gait, try to guess what shoes they are wearing not just whether they are sneakers or how high the heel is, but how shiny they are, how new, how well they fit. Chances are youll be able to describe their shoes most of the time.

To see why shoes have such an impact on our mood, lets take an easy example: the flip flop. You cannot run in a flip flop. You cant even hustle down the street at a New York pace. Your toes are vulnerable to being trodden on, so you are less aggressive walking. To keep the flip flop on your foot, you have to tense up your toes and lunge forward more tentatively with each step. Dog poop is terrifying.

Now, wear a boot. The heel clicks like a metronome as you clatter across the concrete you are on a mission. You could step on anything and squish it without a care. You feel in control, protected, powerful.

Unless it has high heels. Take the most driven, self-confident woman you know, put her in (or really on) a pair of high heels, and not only can she not rule the world, she cant walk five blocks. Due to her shoes, shes become vulnerable. She looks around, like a ballerina, for a prince in stable shoes to hold on to which is probably why she chose to wear such silly things in the first place. (And why he decided to wear those power Oxfords solid, stable, secure.)

Shorten her heel to something a bit more reasonable and voila, you get the power pump. Shes a bit more stable now, but taller than shed be at home; in her power pump, she doesnt have to look up at (or really to) as many people. The calf muscle is already engaged, ready to pounce.

Yet though this seems obvious, think of the last time you consciously thought about how a new pair of shoes would affect your gait. We try on shoes standing in front of the mirror, not parading around Parade of Shoes. Theres a gap there that the MBA student in me wants filled: for some shoe company to really study this relationship between shoes, gait and mood, and scientifically develop shoes that help us better become the person we want to be. Mood shoes.

If thats too commercial a challenge, how about this one instead: isnt it a peculiar coincidence that history is the story of men with boots conquering those with flip flops? Might Jared Diamond have got it wrong that really its Guns, Germs and Boots? Apologies in advance, Dr Diamond: I didnt mean to step on your toes.

Cheers,

Water in the Air

Water in the air is a funny thing. Freeze it the right way, and it comes down in flakes so fluffy that snowboarding feels like flying. Freeze it the wrong way, and it shuts down London Heathrow airport for days when you are trying to get back to New York for Christmas.

With so many thousands of us stranded here in Europe, it’s easy to focus on the water in the air you see. But more intriguing still is the water in the air you don’t see — which once understood, helps explain everything from why we get sick in the winter to why global warming is dangerous.

I stumbled upon this little known fact last winter, watching my cheap Chinese humidifier spray a pathetic strand of fog into the dry Beijing air. Was this thing actually accomplishing anything?, I pondered. I mean, seriously, was that litre of water really going to make a difference? How much water is there in my room anyway — a mililiter? a hundred liters? I had not the foggiest idea.

Before I tell you the answer, take a guess. We don’t usually know this number because humidity gets quoted in relative terms (e.g. 70%), not absolute ones (i.e. grams per cubic meter). Which makes sense: how dry the air feels reflects how readily water evaporates off our skin (and from our sore winter throats). That in turn depends on how saturated the air is, not how much absolute water is in it.

Ok, here’s the answer: air at room temperature is saturated when it holds about 20 grams of water per cubic meter (20 teaspoons if you don’t do grams). So my 4m x 4m x 3m meter room could hold about 1,000 grams or 1 litre of water at saturation, so hmm… yep, pumping a quarter litre of fog into the air would raise relative humidity from a dry 25% to a comfortable 50%. Humidifiers work!

But promoting humidifiers wasn’t what inspired this Aabservation. (Though I am excited to now have an Amazon referrals sidebar on my blog, which you are welcome to play with…) What I also stumbled upon that dry Beijing morning was that 20 grams is only the quantity of water that saturates air at room temperature. Drop the temperature to 10 C (50 F), and air can only hold 9 grams of water — half as much as at 20 C.

Which is why winter air indoors is so dry. Think about it: even if snowing outside (100% humidity), at 0 C air contains less than 4 grams of water per cubic meter. Bring that same dry air inside, heat it up to room temperature (which you’ll remember can hold 20 grams of water), and 4 grams becomes just 1/5 of the total amount of water the air can hold — or an uncomfortable 20% humidity.

No wonder we get sick and our throats feel dry in the winter. Indeed, low absolute humidity is a good predictor of flu transmission, according to a recent study.*

Now think more macro, and you’ll understand how even a few degrees increase in global climate can have a powerful impact on storm intensity. Air at 30C (86F) can hold a whopping 30 grams of water, 32% more water than air just 5C (9F) cooler (see table). That’s 32% more actual water that can then be absorbed into storm clouds and dumped on your beach!

Of course, I am clearly not a meteorologist and this Aabservation doesn’t take into account factors like atmospheric pressure and cloud formation patterns. But hey — this water in air thing is a kind of intriguing, no?

To close, here’s a picture from the Australian government that explains the relationship between humidity and temperature beautifully:

That’s enough about water in the air for one night. Now back to contemplating water in the airport — you know, the stuff that froze Heathrow to a standstill and has pushed my December 21st flight to New York back to December 25th.

On the bright side, maybe I’ll bump into Santa in the air that day. Maybe he’s even bought me a humidifier.

Merry Christmas from London,
