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.

Walk This Way

If you want to dictate someone’s character, buy their shoes.

No, this Aabservation isn’t about how shoes look — it’s about how shoes feel. Sure, a shoe’s appearance sends a message about the wearer’s 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. I’d arrive each place somewhat breathless from walking briskly, my brain whirling with the increased blood flow. One such whirling thought was this: could the city’s 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, people’s shoes were completely affecting their gait. Next time you’re outside, try it yourself: watch people walking down the street, but don’t 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 you’ll be able to describe their shoes most of the time.

To see why shoes have such an impact on our mood, let’s take an easy example: the flip flop. You cannot run in a flip flop. You can’t 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 can’t walk five blocks. Due to her shoes, she’s 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. She’s a bit more stable now, but taller than she’d be at home; in her power pump, she doesn’t 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. There’s 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 that’s too commercial a challenge, how about this one instead: isn’t 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 it’s Guns, Germs and Boots? Apologies in advance, Dr Diamond: I didn’t 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:
Humidity and Temperature

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,
Liz

The Fastest Changing Day

Last week was Autumn Equinox, when day and night are twelve hours each.  Few people realize, though, it’s also the time when the day shortens most quickly.  Indeed, here in London, the day was a full 3 minutes and 54 seconds shorter on September 25st than it was the day before.  This change adds up: in the month around the equinox, our days will have shortened by almost two hours.  You can see this change here: 

 Length of Day (London, 2010)Daily Change in Day Length 

Even if we haven’t spent time on http://www.timeanddate.com/ pondering the length of the day, subconsciously we all are aware that something has been going on recently.  Perhaps we have found ourselves thinking more urgently about all that lies before us.  During the lazy days around June’s summer solstice, when day length narrows by less than a second each day, time feels endless.  But now, when the sun creeps through our curtains a couple of minutes later each morning, we viscerally sense the passage of time.

It’s strange, isn’t it, that we always focus so much on the “equi” bit of the equinox, rather than on the more meaningful fact that the two equinoxes are the fastest changing days in the year.  It’s especially strange when we think how obsessed we are with rates of change in other arenas, like GDP growth, up-and-coming celebrities, and progress. 

Here we are, though, stuck on this spinning orb, each day tilting further away from the warming rays of the sun, further towards the cold dark emptiness at the end of solar system.  So we gather up a blanket against the coming chill, and ponder what it all means. 

 And just at that moment, a happy thought shines in:  from now on, at least, the days will no longer shorten as quickly. 

 - Liz

p.s.  Ok, I’m not an astronomer, and it be that the equinox is not actually the fastest-changing day, but a few days before/after it.

p.p.s. And for those of you in the Southern Hemisphere, enjoy the coming summer!

London White

I can’t get over London White.  It’s such a beautiful color, and is everywhere here in London:  lining window frames on stone buildings, coating interior walls, painted over elaborate moldings on hundred-year-old ceilings, stripped across black asphalt to tell you to ”Look Right –>” when crossing the street.  London White is a majestic white, that demonstrates its specialness, privilege and pride in a way so subtle and polite it could only be English.  In China, by contrast, pollution would turn the sides of any white building to a chalky grey by mid-afternoon.  London too was once as polluted, and not that long ago.  This London White tells that hopeful story too, of how much a place can change in just a few decades.  But not just by dreaming:  it’s a white that requires constant care, which here is done quietly.  Look closely, though, and you’ll see residents with a soapy sponge wiping down their window frames on a Saturday afternoon, or ”Wet Paint” signs taped to newly repainted white corner posts.  It’s a time consuming white, that requires patience that New Yorkers like me can’t be bothered to have;  we’d prefer indestructible, dirtiable, resilient black, thank you very much.  Since this white is so vulnerable, it’s a trusting color too.  It assumes the best in others:  that strangers won’t put their feet up on the white bench, or spill red wine on the white carpet.  For immigrants to the UK — who come in all colors — London White is useful:  a clean background upon which we can start painting the next chapter of our lives.

Leaving China

I leave China tomorrow, after four and a half years here.  I am heading out to get an MBA at London Business School (LBS), a two year program that has me graduating in the summer of 2012 (just in time for the London Olympics!). 

As my time in China comes to a close, I’ve been thinking a great deal about endings.  They don’t happen in a moment or even a day;  it’s not an “end,” after all, but an “ending.“  I am now, for instance, writing from a hotel in Beijing, as I moved out of my apartment this morning.  Did I stop living in Beijing this morning already; or will that happen tomorrow, maybe when my flight leaves the tarmac?  Ending three years at Kamsky Associates has also been a gradual ending.  While my last day was June 18th, I started transitioning most accounts to my colleagues long before, and will surely stay connected to the people I met there for many years to come.

But while my time in China is ending, there was a clear moment today when my time in Beijing abruptly ended:  when I walked away from my bike.  You see, China is a country — a concept. But Beijing is a place.  We tend to think that places are concepts too, perhaps defined by the people in them, their vibe, their ascetics, their history, their ideals.  But I would argue a place is just that:  a place, a physical location.  Maybe it’s just that I’ve been reading Omnivore’s Dilemma and watching too much of BBC’s Life series, but I do think that our brains are hard-wired to pay particularly close attention to our physical surroundings.  It’s important for survival to know how to get home, where to find food, and where to avoid becoming food as well.  Or if that’s too caveman-esque of an example, how’s this:  what I suspect I remember most clearly from my childhood are the locations of the hidden “1-UPs” in Super Mario Brothers.  Indeed, now two decades later, if you put a Nintendo controller back in my hands, I bet I would still know that the 1-UP was hidden in the red brick four steps to the left of that pit (you know, the one near the two black-shelled turtles that hit each other and change direction just as you come on screen).

Like a Nintendo controller, my bicycle helped me understand Beijing by letting me understand its “placeness”.  When some people think of Beijing they think of the Olympics, or Communism, or cheap ties.  For me, though, Beijing was the (unnecessarily high) speed bump near my apartment, and the smooth and rewarding downgrade heading east off Dongsishitiao, and the patter of the packed ping pong tables near Jianguomenqiao that I would pass on my way to work.  And, since I could bike to most destinations in under half an hour, regardless of traffic, my bike helped make this sprawling and often congested city accessible.

So, you can imagine that abandoning my bike today (albeit to the kind ownership of a friend and colleague) was really hard.  I wasn’t just leaving a bike, I was leaving the tool that let me play in this amazing city, get around it, and, in my way, understand it.  Outside of Beijing, I can still read about the city’s economic and political developments.  But how will I know if they finally put a pedestrian traffic light on the western crosswalk of Xin Dong Lu and Dongzhimenwai?

Hmm, it’s getting to be that strange time between night and morning now.  A good time, it seems, for this Aabservation to come to an ending.

The Elevator

I got into the elevator on my way to work the other morning, brow furrowed with something or other on my mind, and pushed “19″ for my office’s floor.  On the fifth floor, when one of the passengers I hadn’t noticed got off, a cleaning lady stepped into the elevator with a cloth in hand.  She didn’t push any buttons, nor did she turn to face the doors like most elevator riders do.  The doors closed behind her, and she turned to polish the brass trim on the wall.  When we reached floor 19 and I got off, the cleaning lady remained inside, with no buttons pressed, indifferent to where the elevator would go next.  Instead she just continued polishing the brass, to make it a nicer place to spend the few moments of our journeys, a master of the art of riding elevators.

Thumbs Up for Brazil

It’s late April and still winter in Beijing, but two months ago, I got a preview of summer when I was in Brazil. I used to think that New York was halfway around the world from Beijing. But after my 14 hour flight to JFK (where I stopped to have lunch in the airport with my dad), I boarded yet another 10 hour flight to Sao Paulo – 17,599km all told as the crow flies. Only Argentina would be farther away.

It’s now been a while since I was there and this interminable Beijing winter has messed with my mind, so I apologize for only sharing the impressions of Brazil that I can still recall. I was there for about a week, in Sao Paulo, Rio de Janiero, and some of the coastal beach towns, mostly to see a good friend and her fiancé who are living there this year, and partially to replenish my body’s store of Vitamin D. I was not there to observe anything intensely, except perhaps how to make a proper caipirinha.

Having said that, here’s what managed to stick in my mind:

1) Obrigada: I clearly don’t speak Portuguese. After living in China for 4 years, when I even tried to speak Spanish, it came out Mandarin. I did learn one word, obrigada, which means “thank you”, and think that’s all you really need. It’s said in the slow, chilled way that all Portuguese seems to spoken there — just enjoying the sound of itself. I don’t know if all Brazilian people are kind and helpful, but certainly the ones we met were (except that taxi driver that gave us a tour of all of Sao Paulo on “the way” back from the Carnival parade). People seemed happy to try to help everywhere we went — so really all you needed to be able to say was obrigada.

2) Diversity: When the flight attendant started speaking to me in Portuguese, I realized that — unlike in China — you cannot tell by looking at someone whether they are Brazilian. Brazil is full of immigrants. How well they get along I leave to other people to answer; the sun was too bright to tell from my beach blanket.

3) Food: Meat, fish, fruit — all amazingly fresh and well-prepared. No wonder my jeans were tight after a week there.

4) Carnival (Mardi Gras): We watched a Carnival parade in Sao Paulo the night we arrived, which lasted for 5 or 6 hours (longer than we did, anyway). The parade went down the middle of a street lined with stadium seats, to which one bought tickets. There were a thousands of people from the local communities wearing extremely elaborate costumes and dancing/shuffling to a repeating samba chorus. Ever few hundred dancers, there would be a fifty-foot tall float, often of a person dancing, with more people dancing on it. At the end, torn up costumes were lying around everywhere.

5) So pretty: Rio de Janiero must be the most beautiful city in the world, with tall buildings woven between green hills and blue lakes. And how our friend managed to keep his eye on the road when we were driving up the coast is a mystery — so pretty everywhere. I hear there’s a rain forest somewhere in there too…

6) Thumbs Up: This I loved: everyone gives each other a thumbs up after asking for directions, or having a door opened, or getting change back, whatever. There was just something really chilled out about the people there, and this thumbs up thing underscored it. Even before I arrived in Brazil, when I was getting my visa at the Brazilian Embassy here in Beijing, the Embassy guard just told me to swing the fence open and go on in. In the U.S. embassy, by contrast, you have to walk through four layers of xray machines, marines, and double-locked doors to get inside.

Sure, there’s more things to observe about a massive country like Brazil — poverty, development, BRIC status, sushi, churches and cemeteries, and helicopters come to mind — but let’s do this instead: when I see you next, I’ll make you a caipirinha, and we’ll find somewhere sunny to chat about it all. Would that work for you? Awesome. Obrigada.

About Stuff

Chasing after a rickshaw piled seven feet high with every item of my personal belongings last weekend, I remembered why I hate stuff.  I was just moving out of my apartment with the help of the guy who collects trash in my neighbor, and his dirty-but-sturdy leg-powered rickshaw.  Since I was living in a walk-up, last Sunday involved the rickshaw guy, me, my old roommate, and my new roommate (aka my sister) walking up and down five flights lugging ricebags of clothes, boxes with stereos, pillows, clothing racks, shoes, a camel pen my sister got me in Egypt, a pink felt cowboy hat I bought at the Houston Rodeo, squash rackets, a clay sculpture of myself that a colleague had made, a foot-thick queen size mattress, some Trader Joe’s dark chocolate covered espresso beans, my high school prom dress, … and whatever else made up those 43 bags, boxes, or pieces of stuff.

Why do I — why do we — have so much stuff?
 
One answer is that stuff is cheap.  Just a few minutes ago, for instance, the guy came with a fresh jug for the water cooler in our apartment.  The only place to put it right now is on a chair, which causes the cooler to tilt precariously.  My solution to this tilting problem is not to find another place to put it, or to try to level it, but instead to go tomorrow to buy a cheap flat-topped stool.  A stool that will be more of this very stuff that I supposedly hate.

And second, we like buying cheap stuff.  It seems obvious, but it’s not.  For a long, long time, we liked buying good stuff.  Cheap meant crappy, and no one liked crappy.  We liked buying a few good things that lasted, and then taking care of them well. 
 
But then things changed — at least in America:  First, quality stuff became cheap, thanks to the joys of mass production, efficient supply chains, competitive pressures — you name it.
 
Second, publication costs fell so much that media had to become dependent on advertising, not subscriptions. Those ads have accomplished their mission:  they help us want to buy cheap stuff (and expensive stuff, too).  Online newspapers are a great example of how cheaper publications costs have helped make ads a bigger part of our life.  For instance, newspapers can charge $0.10 per view per brick and mortar ad, but only $0.001 per view for digital ads on popular sites (for instance, with more than 100,000 views).  A friend who has worked on optimizing web-based ad displays believes that advertising will get better in time at targeting potential buyers, thereby permitting online newspapers to charge more for their content.  If so, newspapers can afford to keep providing content we want, and we’ll see more, and more effective, ads that make us want to buy stuff too.  The printed book — arguably the last domain of unadvertised content — will soon follow the ad-model as e-books gain popularity;  the next generation of e-books are already planning on serving ads.
 
And a third reason we have come to like cheap stuff is that we first learn to buy things when we are teenagers.  Teens face the tremendous task of figuring out who they are, and who everyone else is.  One great way to do that is to identify and buy the latest, most popular thing.  The “latest” part requires buying a lot as trends change.  “Popular” requires buying things that most people can afford to buy and then throw out a few months later.  In other words, teens learn quickly to like buying cheap stuff.

So looking my rickshaw wobbling down the street, I wondered whether having so much stuff is a bad thing, other than when moving, and if so, what, if anything, we can do about it.

I have some thoughts, but for another time.  Now, I have to get back to putting away all my stuff.

The Concrete Floor

The hare had escaped.  The farmer yelled at his hunting dog, “You’re a highly trained animal!  How could you let that little hare outrun you?”  The hunting dog replied, “Master, I was merely hunting for my lunch;  he was hunting for his life.”  — Aesop’s Fables

I recently went back to the U.S. on a business trip, and caught up with friends I haven’t seen in a while – so the usual ten minute synopsis of recent developments in their relationships, job, and education.  My friends are at the age now where summer is now just considered “wedding season,” but people don’t really have kids yet.  It’s a moment when we’ve finished processing all the norms our parents gave us, and are now deciding what ones we consider our own.

One such norm is gender equality, specifically in the workplace. Thanks to the women’s movement, men and women can, at least in theory, now do the same jobs, get paid the same for doing them, and advance to the same seniority at them.  My mother fought hard for that privilege.  She was one of ten women in her medical school class of over a hundred.  Thanks to my parent’s generation (and my parents!), I could attend a formerly all-boys school in New York, play baseball on a co-ed Little League team, work on a historically male Wall Street trading floor, and drink scotch at a formerly all-male New York Athletic Club.  I have been told me there’s a glass ceiling somewhere out there, but I haven’t yet felt it.  We women have my parents’ generation to thank for such liberty.

And yet, I don’t have to look too far ahead to see something that looks suspiciously like a glass ceiling still out there in the workplace.  I don’t need to barrage you with statistics proving that there are notably few female CEOs, directors of companies, or Congresswomen in the US.  Here’s one fun fact though: Lehman Brothers, where I used to work, promoted 199 people to Managing Director last year. 176 of them were men. Only 23 were women. 

So why, after all these decades of gender equality, are women – ambitious, talented, smart women – still not keeping up with men in the workplace?

It’s not just the “glass ceiling” preventing women from rising higher.  There’s also a “concrete floor” preventing men from falling behind, a floor built by you, and by me.

When cars meet bikes

I got hit by a minivan yesterday while biking along the highway that makes a ring around inner Beijing.  It had just been raining.  The defined bike lane, usually separated by a row of trees, had just ended as a road branched off the highway.  To my right was a moped veering left to avoid a deep puddle, and to my left, a minivan that was veering right to exit.  Between them: me, hitting the brakes of my beloved bicycle;  my shoulder, hitting the moped;  my back wheel, hitting the minivan’s back wheel. And then my rear reflector clattering across the concrete.

The minivan pulled over, and a young couple came out.  After their initial confused emotional angst, they kindly asked if my bike was broken.  “Did you get hurt?” I hadn’t even tipped over and didn’t have a scratch.  Only the splashguard over my rear wheel was warped, so that it pinned the tire in place.  “If we had tools,” the wife said, “we’d definitely help to fix it.”  They seemed genuinely concerned.  Eventually there was nothing more to say, and they drove off, maybe a little slower this time.

I grabbed my bike with its immobile back wheel, careful not to get grease on the suit I was wearing, and carried it a few meters looking for a place to park it overnight until the bike repairmen returned to their street carts.  There, by chance:  a woman standing by the open hood of a car; a man crouched next to a fan and some piping;  and a wrench.  I asked the auto repairman if I could borrow his wrench, and he instead got up without ceremony, took out some tools, and expertly repaired my back wheel.  He refused a tip. Even the woman didn’t seem bothered that he interrupted fixing her car to help me. Eventually, there was nothing more to do, so I biked off, maybe a little slower this time.

Getting hit by a minivan reminded me why I love China.  There are so many people here that you can’t avoid bumping into them once in a while — sometimes they’ll break your bike, sometimes they’ll fix it. In Beijing too, there’s that same persistent “plodding along” that I felt in New York this March; despite the pounding pace of change, such patience.  Perhaps it’s because things have been so hard for so long, Chinese people I’ve met tend to recognize what’s horrible, and what’s really not — and then they shrug off the stuff that’s not.

Next week, the US and China, one land known for its cars, and one land known for its bikes, will meet for the Strategic and Economic Dialogues in Washington, D.C.  The headlines, I suspect, will focus on the collisions, since people like to read about accidents.  Admit it.  You’ve been reading mine.

But I hope that the real story will be about how the US and China can help each other out anyway.  That sometime during those two days, Treasury Secretary Geithner turns to his counterpart at the SED, Vice Premier Wang Qishan, and says, “Hey, sorry you got hit by this financial crisis thing.  Did you get hurt?”  And maybe in response Wang Qishan will look at his wounded economy, which isn’t really that horrible, shrug and say, “We’ll be alright.”  At some point, after all the tea and coffee is drunk, there’ll be nothing more to say.  And so the US and China will set off on their own ways as they work to rebuild the world economy in their own ways.

Maybe a little slower this time.
