It's time. So many feelings at going home but leaving home. Anybody who's emigrated and lives away from their land of birth, friends and their family will recognise all the emotions, heartache, excitement, loss, despair and exhilaration that this travel moment brings. Hugs to all those world travellers out there facing this moment - stay strong and be kind to yourself - allow yourself to grieve even though you're going back home. xoxo

where next?

on the move yet again
Where next - why London of course! Final leg of the Spring Break Tour 2017.

... and since we had some time to spare with our early arrival, we checked out both the British Library and the British Museum (open late on Fridays) on two whistlestop fly bys.

collecting lions as we go: this one is nebuchadnezzar's
Very whistle stop - short attention spans and whatnot.
But we 'got' the general atmosphere.

chessmen ahoy! prepare to be captured

And we saw the Lewis chessmen 'in the flesh' so to speak.
Mission accomplished :)

The Details
Have I mentioned how very much in love I am right now with Google Maps? (and btw, here's a link to the location sharing feature coming soon: As a smartphone app, it has almost completely taken over from guidebooks. It was great for navigating in Venice and is now proving ideal for route finding in London.
How did I ever manage before?

out and about there and back

border hopping on a sunny but windy day (ahead of the snow)
Still playing catch up with the blogging ...

Spoiler: we did make it back to Edinburgh and escaped the industrial action. Apart from not much sleep the evening before, we landed in Edinburgh unscathed to pick up our hire car.

Dear reader - I sped over the Scottish border in a Smart Car...

lets it sink in ...

A four-door Smart car.
Not great for long distance, and it catches the wind like a kite.

So maybe I should say that we sailed over the scottish border into Northumberland.

in its natural habitat
Day Thirteen was thus recovery day.
This is by no means because of a late night out with friends, catching up with old times, cheering absent friends or playing Exploding Kittens.

Wee Guy and I checked out Barter Books, the British Library of secondhand books, which is conveniently within a 10 minute walk of our rental. It was busy around lunchtime but we still managed to find odd nooks to tuck ourselves into next to the books.

most perfect bacon sandwich ever IMO ...
For lunch we trotted down to the Treehouse in Alnwick Castle's grounds. Wee Guy had a perfect bacon sandwich, which he described as being plain and only having bacon ... in other words, a perfect bacon sandwich. And the bacon! thick, meaty, juicy, pink ... in other words, not like Canada's pale excuse. The restaurant kitchen salvaged my tasty but gag-inducing roasted garlic and mushroom by sieving out the stringy vegetable matter that made each swallow an ordeal. The result was a velvety smooth veloute that I am not sure why they didn't provide in the first place. Top marks for customer service on my complaint though.

books. cohen. trains

After a wander round Alnwick centre we ended up back at Barter Books for book #2 and cake :)

stables and ghost
Day Fourteen
Day 14 was family day, catching up with mother-in-law/Granny Kate for a chilly but enjoyable day at Seaton Delaval Hall. As stately homes go, this one went up with a whoosh! in 1822, with the west wing remaining roofless for around 40 years. Today it is an amazing architectural skeleton that allows visitors to see the bare bones that usually hide under layers of plaster and wood panelling.


The west wing is roofed and undergoing restoration - speaking with the guides gave us some insight into the history and the work currently underway to preserve the building. We also learned about the ghosts but luckily after we'd scrambled through the cellars.

Day Fifteen
More stately home visiting and this time to Bamburgh Castle on the coast. Wee Guy and I bounced up the winding roads in the Smart car (nope - never buying one) and spent the day checking out Lord Armstrong's pile and then paying our respects to Grace Darling.

... followed by packing ... where next?

the details
Not much to note here, except that if we'd been visiting more National Trust properties like Seaton Delaval Hall it would have made sense to buy a membership to decrease admission fees.

Oh, and not sure if this is relevant but beware booking car hire online. Sometimes the cheapest option might not be as good as it sounds. I booked through what looked like an aggregator since the rates quoted were extremely low. however, when I checked the find print for zero deductible premiums I found out that even with zero, you still have to pay up. What brings it to zero is that you then have to put in a claim to the aggregator company ... ho hum.

I rented directly from Europcar, picking up at one airport and getting one-way hire (extra 46GBP) to drop off at another. My premium package to reduce the deductible to zero cost around 75GBP for four days hire plus around 30GBP for roadside assist. And I bought a full tank of gas for around 33GBP so I didn't need to hunt out a refueling stop before return.

out and about vaporetto style

my travel sidekick
Playing catch up here with the blogging after some busy travel times.

On our second day in Venice with vaporetto tickets, or in other words day ten of our spring break vacation (please try to pay attention), we vaporettoed the heck out of our travel privileges!


First stop - the Lido. Where we experienced cars on roads and the faded excellence of a seaside resort out of season. Closed down arcades and fenced off lookout towers. A chilly beach and grey skies.

Guidecca seaside stroll
Followed by a a counter-rotatory trip around Venice and on to Guidecca, another island but no cars ... just artist studios and a lot of dog poop along the seafront ...

dragster from 18th century Venice, i presume

Day Eleven
... which of course is day four in Venice and thus day -1 of unlimited 48-hour vaporetto travel (you are paying attention?) was palazzo or bust. We ticked off the textile and costume museum at Palazzo Mocenigo and then navigated thru Dorsoduro to Ca' Rezzonica. The displays are incredible but what's even more impressive are the surroundings they are in - these are impressive palaces along the Grand Canal.


Even if you don't like the subject matter, the ornate staircases, mouldings, strangely lopsided door hanging and remnants of an opulent days-gone-by lifestyle are worth the visit. Again, the museums pass from Venezia Unica is worth the price. We didn't stay longer than about two hours in each museum so far on this trip; we stayed longer in the Doges Palace on our last, but paying full price imposes an arbitrary time-to-cost benefit ratio that discount passes don't guilt you with.

yes, of course i managed another aperol spritzer :)
Homing instinct kicked in for late afternoon. On hostess Giulia's recommendation, we stepped inside Fondaco dei Tadeschei, the Venetian answer to the luxury shopping mall. It's right beside the Rialto Bridge, on our route home, and is yet another palace I think. Formerly a German merchants building and then a post office with a side association with Mussolini, the building lay empty for a number of years before its recent (and sensitive) transformation. It is four floors of opulent shopping, each floor with amazing views of the Grand Canal and rooftop Venice. The top floor contains an exhibition area and the roof terrace is free to visit. However .... the tickets are timed so we didn't get out for the views. Hint: visit the ticket booth on the top floor first, then go for a coffee.

lots of floors of really expensive shopping
and a good cafe

Packing took the rest of the evening, punctuated by taking the recycling out and then worrying about the Italian air handlers strike for the next day ... spoilers!

Art and Technology: When Worlds Collide

via Amanda Maxwell – Northrop Grumman

Friday, March 17, 2017

out and about offshore

in my happy place
Today we activated our travel passes then headed off to the glass mecca that is Murano. Everyone has heard of Murano glass but the tricky thing is getting your hands on genuine pieces. Every single shop on Murano sells glass; many of them just sell glass cheaply; most state that all the glass sold therein is genuine Murano glass; some say it is Murano glass handmade on the island; a handful have Murano accreditation.
A lot of the shop windows contain identical glass pieces.
Some shops are expensive.
Some are very cheap.
Some loudly proclaim No Chinese Glass.

sigh ... glass
I am still not sure how to buy Murano glass made on Murano ...


The glass museum, refurbished since our last visit was a treasure to view. The displays are beautifully spaced out and a feast for the glass lover's eyes. Historical pieces flow chronologically from Roman to modern, with educational videos on the various techniques exploited so brilliantly by the Murano artisans.

sailing up to the Rialto on our budget tour
After Murano, we made excellent use of our travel passes by sailing all the way around the southeastern end of Venice, past Arsenale and the shipyards, to the Biennale site where we disembarked. By uncanny accident we found ourselves at the every same cafe as we had collapsed at three years ago. Enter cake, hot chocolate and an aperol spritzer. No cat this time :(
Making even more use of the travel pass, we completed our Grand Canal voyage via ACTV vaporetto line #1, getting off at Casino and then walking home.
My ankle aches but my heart soars.
Already I want to come back to Venice!

plotting the next trip?
The Details

  • Venezia Unica for travel passes - buy them online in advance then swap the voucher for tickets on the day. Choose from the daily or single tickets, or splash out on the far less restrictive multi-day options. I noticed that there is also an ACTV smartphone app that allows you to buy and download tickets to your device. Haven't used it yet but noting for the future ...
  • Murano is easy to reach  just check the ACTV routes and timetables. Check before boarding - a single word, Murano? is usually all that is needed. The vaporetto crews have been wonderful on both our trips.
  • DIY budget tour the Grand Canal courtesy of your travel pass. Line 1 zigzags from San Marco all the way through; line 2 takes a faster passage through. If you're lucky and the boat is not packed, try sitting at the front and pretending this is your private gondola.

out and about circling back

still not quite believing we're here ... St. Mark's Square, with the Doges Palace
We are in Venice.
We were in Scotland, but thanks to EasyJet, we're now in Venice and staying in the same apartment as three years ago. :)

We arrived late last night and remembered our way thru the maze of calles and alleys and snickets little wider than a handspan. We carried our case over the bridge steps, followed the blue dot on Google maps, and buzzed in to see the amazing Giulia once more.

apologies for the frenetic slideshow but google pics doesn't do movies from desktop :(
scenes from the Natural History Museum, Ca' Pesaro Modern Art Gallery and various navigations

This morning we shopped in the most elegant grocery store I have ever seen, then missed a traghetto (OK, we couldn't find it), walked the bridge route across the Grand Canal to visit the Natural History museum and Ca' Pesaro, the modern art gallery.
In between the dead animal abundance of the former and the inspirational canvases of the second, we had our first gelato ... priorities.
And we keep pinching ourselves cos surely we must still be sleeping ... #backinvenice

putting our heads together - Rodin, ebb and Martini/Gish
the details

  • easy peasy Easyjet flight from Edinburgh to Venice, limits us trans-Atlantic travellers to only one piece of carry-on luggage and a max of 20kg for the suitcase #packlight
  • purchase the onboard vouchers for food etc ahead of time ... but don't go nuts. They are only valid on the flight you specify :( #boughtalotofkitkats
  • depending on where you are staying, the Alilaguna boat shuttles direct from the airport make a lot of sense. They are more expensive than the train or bus transfers and much cheaper than a private watertaxi. Book the voucher online and exchange on arrival at the ticket office. For us, the convenience works. It's also a great way to arrive in venice during daylight - there's nothing quite like seeing the city skyline 'floating' emerging above the lagoon surface. Maybe not an option if you don't travel well by boat ...
  • visit the Venezia Unica website for all sorts of discounts and travel tips before arriving. We bought a museum pass for all 11 civic museums and have two days of unlimited vaporetto travel sorted. You want to do it ahead of travel since you need the printed vouchers to claim your tickets, etc. 
  • crossing canals is easy on foot if you can find a bridge; vaporettos are an expensive way of getting around for tourists unless you buy a pass (see above). The alternative is a 2 Euro ride on a gondola ferry or traghetto. Street maps of the city show where these cross the Grand Canal (apparently) but note, they are not regular and seem to run to their own schedules. It is however a cool way to get on the water.
Schrodinger's traghetto perhaps - we saw it on the water but not at a landing

out and about back to school

Interactivity rules at the museum

Still bucket listing.

Day Five (Monday)
Wee Guy and I headed back in to Edinburgh, on an earlier train so we could get back before the dreaded end of off peak. Stopped for coffee in the excellent cafe in the basement of the National Galleries on the Mound and added a couple of pastries to start our day. He picked up the book he'd spied on our earlier visit; I mapped out a quick sketch.
Gazing into the old town from the new

From there we headed up the steps towards the Royal Mile and on to the museum in Chambers Street again. We highly recommend the interactive exhibits in the science and technology wing ... they all worked, unlike some other places we've visited recently cough cough hrmacmillanspacecentre ...
There's also a wonderful fashion and textile display, focusing on the influence from Scottish fabrics and designers.
School and workplace

For our lunch, we headed south past the university buildings - McEwan Hall where I graduated, Teviot Row student Union with the showers with unlimited hot water, and my beloved Green Banana Club of yore at Potterow - to the Dick Vet at Summerhall for lunch. For a former student, wandering the hallways and stepping into the old library brought back lots of memories (good, bad, terrifying). Instead of hospital kennels there are now a distillery, sweet shop and art installations. No more radioactive cats in quarantine! Summerhall is home to the largest Arts complex outside London. We had a very tasty lunch in one of the surgery lecturer's offices under the surgical suite that I worked in briefly!
Late for a lecture?

It felt almost as odd revisiting the Dick as it did working there immediately after qualifying ... and with my son along for the ride too.

From there we headed back to the museum to catch a few more exhibits (museums - best in small doses), before catching our off peak return.
Rooftop Panorama at the museum
The Details

  • Family and Friends Railcard (£30) make train travel even cheaper
  • Entry to the galleries and the museum is free; pay extra to see certain exhibitions. Free access to the museum roof deck is a must for sunny and clear days
  • Summerhall is open all week though certain galleries are closed on Mondays. The lecture theatre were closed when we visited and so was the dissection room where the formalin fumes from the cadavers killed off my respiratory cilia :(

out and about making a splash

lifeboat ahoy, but no whale ...

So far ... family, friends, beaches and whales ...
Family - check
Friends - check
Beaches - check
Whale - so far unseen, even though we were in the right area :(

Day Three (Saturday)
Day three was family and friends day, catching up with an aunt, an uncle, a neighbour and a childhood friend. Also, catching up on bits and pieces of work that travel with me. Wee Guy went to hang out with a local friend and also learn that 'tea' means dinner over here.


Day Four (Sunday)
This morning we travelled along the coast to Kinghorn, to visit the lifeboat station. This charming little seaside village fields three full inshore lifeboat crews out of a population of 2,930. All boat crew must live within the village, and must not leave it while on call unless they arrange cover.
We saw the boat returning from a practice run, when the tractor unit picked it up on the trolley by driving into the waves. Then we chatted with crew and other volunteers (yes, the crew are volunteers too - they don't get paid for training or for going out on rescues).
... they're recruiting too, but I think the Wee Guy is a little young.
Kinghorn seaside

Later, we made our re-acquaintance  with the local castle, another beach, took two busy terriers for a walk, and resumed a conversation that was started a year ago while shrugging off a few more grams of jet lag. Happy travels :)

out and about home and away

sunshine, in march, in scotland ... #endofdays

(subtitle: a real blog post)
We're on holiday.
To clarify, the 'we' is myself and the Wee Guy, and 'on holiday' means back in the UK visiting family.

So far, we've kicked jetlag (ok not quite but this time has been brutal), missed the off peak train travel back from Edinburgh and spent dinner time in the city, walked along the harbour, walked the dog, and walked round Edinburgh.

We've caught up with family, friends, old haunts and coffee.
We've caught sun and grey days.
We're missing home but having enough fun to not miss it too badly.

The Details (in case you were wondering)
  • Flight from Vancouver to Edinburgh via Heathrow.
  • Use free airport wifi to Skype grandparents to let them know of our arrival and when to expect us. (Turn off all data, roaming etc. to avoid a nasty shock on return home).
  • Test Canadian bank card in UK ATM - success!
  • Airport shuttle into Fife.
  • SIM cards from - If you have a UK delivery address, send off in advance for a free pay-as-you-go SIM then pick up a top-up voucher at WH Smith or similar. Credit card top ups do not work unless you have a UK billing address :( Once topped up, convert your top up into an Add On that will last for 30 days for additional value. 
all sunny at the end of the harbour
Day One (Thursday)
lenses from lighthouse in museum main hall
  • Ugh jetlag migraine ... glorious sunshine not helping (scotland ... march ... sunshine ... wtf?)
  • Slow walking with dog ... left behind by grandparents going longer route (oh the shame)...
  • Pooh sticks from the bridge ... realise parenting failure as Wee Guy thinks nana is actually going to make him handle poo sticks ... 
  • Fail to obtain pre-booked rail tickets from station ticket machine a too jetlagged/post-migrainish to remember which credit card ... increase anxiety in Wee Guy who now does not believe he is under care of competent adult ...
  • Afternoon nap ... unconscious for several hours ... Wee Guy discovers Doctor Who on Netflix again ... holiday plans now sorted!
the Writers Museum: free entry and worth it to see
inside this amazing building

Day Two (Friday)
  • Ticket success requires insertion of most of my credit cards into machine.
  • Train travel bucket list item checked
  • Yo Sushi! lunch bucket list level achieved
  • Brief arting stop at National Gallery to giggle at books, then onwards via Writers Museum and Royal Mile to National Museum on Chambers Street to catch up with soon-to-be Dr. Ryan for tea and cakes (and museums)
  • bounce down the marble Scotsman Steps
  • Off peak hours pah! Dinner in town. Bonus: seeing Edinburgh all lit up

Follow along on Rebel Mouse for more pics!

Reflecting self

Self-portrait of Rosetta during Mars flybySelfies. Definitely notorious in the digital world. Who hasn’t wrinkled up their nose in disgust at a friend’s shameless self-promotion or puckered up a duck face for the camera?

Or maybe selfies power your voyage of exploration for personal acceptance, understanding and confidence.

Universally reviled, or defended as an act of self-expression. A moment of attention-grabbing vanity or an opportunity for reflection—what exactly is the deal?

Selfie history

The earliest selfie was recorded in days when point-and-click was more like click-run-stand very still. Today, due to digital cameras in general and the omnipresent smartphone in particular, more than one million self-portraits are taken and uploaded to social media every day.

Selfie fails

Analysts suggest that selfie-taking is narcissistic, that men posting selfies display signs of psychopathy and that all it really shows is that we haven’t moved on from self-obsessed toddlerhood.

Described as a marker of the YOLO generation, selfies provoke outrage and despair. It’s catchy to point the finger at deaths from extreme-risk selfie-taking. Selfies also seem to indicate social and humanitarian obliviousness; one artist started a Yolocaust collection, collecting images taken at Holocaust memorials, then Photoshopping them to show how disrespectful and unaware the photographers seemed to their surroundings.

Selfies for good?

Okay, not an actual arm’s-length selfie … but there’s also a turtle (a giant one) involved!

However, selfies also get some positive press. Harnessing their self-promotion aspect for communication spreads awareness and exploration.

  • The ice bucket challenge selfies boosted online donations to ALS research by 400% in just one month. This funded the discovery of a new gene associated with the disease.
  • Vancouver photographer Vivienne McMaster uses the #beyourownbeloved hashtag to grow a community founded on selfies to explore and enhance body positivity.
  • And science also uses the selfie to push against boundaries, both social and research. Who remembers #distractinglysexy? Female scientists took to social media to mock a senior scientist’s assertions that women were not a positive presence in the lab. And how about the highly personable shares between Philae, Rosetta and their “handlers” back on earth that captured the moment for space exploration?

Or maybe you use them as another way of archiving, forming a visual diary of events and happy memories—all at arm’s-length (or selfie stick, if you prefer).

Long-range selfie

At much longer range, further than the longest arm and the most extensive selfie stick, selfies inspire deep reflection.

The first images taken from space came from cameras aboard a 1946 U.S.-launched V2 rocket. They show the topography from around 105 km above the surface, five times higher than ever before.

The Explorer VI satellite launched in August 1959 took snapshots of our beautiful blue planet from 17,000 km above Mexico. This one captured cloud cover over a sunlit patch of the Central Pacific Ocean—a little fuzzy, but hey, that’s us!

earth rise captured over the lunar surfaceThe crew from Apollo 8 took the first human-powered selfies way back in 1968 as the spacecraft orbited the moon. The photos show the earth as a whole planet from around 30,000 km away, in all its blue and clouded wonder. The astronaut crew also captured the first earthrise over the lunar surface.

And then there’s the late Valentine’s gift: a selfie from 6,054,587,000 km away. Carl Sagan’s pale blue dot came from Voyager 1 as the space probe looked back one last time before heading off into the void of deep space.

So, what do we see from these (very) long-distance views of self? Do we see bad hombres or mounting terror, the need to build walls, perhaps? Or could we gain from their self-reflection? As Sagan himself suggested, the pale blue dot “selfie” highlights how much we need to care for our unique and fragile tiny globe in space.

Death of the stethoscope?

By Font Awesome by Dave Gandy -, CC BY-SA 3.0, LinkIt’s not just zombies that rise from the dead—science news stories can also come back to haunt the reader.

Take “Death of the stethoscope,” which surfaced in my RSS feed in the middle of 2015. As a former stethoscope user, the clickbait headline immediately intrigued me.

No stethoscope? How would clinicians survive?


First off: a little history. According to his Wikipedia summary, a French doctor called René Laennec invented a hollow hearing tube in 1816 to assist doctors in listening to a patient’s heart and lungs. Around 1852, the single tube morphed into the standard model that you see plugged into physicians’ ears from Grey’s Anatomy to House to ER. Apart from making them look hot professional, a stethoscope also helps with auscultation, the examination procedure whereby a doctor eavesdrops on your internal whooshes, pings and lub-dups. Noises from heart rhythms, gut movements and respiration all help with making a diagnosis since a lot of this internal chatter is very specific.


According to the headline(s), the humble “manual” stethoscope is on the edge of obsolescence in the medical world, facing a high-tech upgrade to or even replacement by hand-held devices that apparently do the job better.

The Motherboard post on adopts its title from Adel Birbari’s article of the same name, published in the Lebanese Medical Journal in 1999. It suggests that clinicians favour high-tech USB-powered digital over rubber tubing, echoing a point in a press release from the World Heart Federation released the previous year. An article in the Washington Post from January 2016 repeats the call for replacement with something more appropriate to the digital age.

The number one contender to replace the stethoscope is a portable, hand-held ultrasound device, but this is closely followed by digital adaptations ranging from electronic versions to the Eko CORE, a digital add-on that works with the traditional stethoscope to amplify and record sounds. By Põnn [CC BY 2.5], via Wikimedia Commons Practicalities

While it is refreshing to learn that technology has not passed over such a basic piece of diagnostic kit, I do have some concerns about encouraging clinicians to dump the familiar neckwear or even to abandon the professional skill of auscultation.

As a former practising veterinary surgeon, some of these reservations do have a practical component.

  • Distance: Number one for me is that being at the earpiece end of a stethoscope removes my face somewhat from the immediate danger zone, whether fanged or hoofed. Apparently, this also is why Laennec came up with his idea, though he was more interested in staying away from the heaving bosoms of well-padded female patients than avoiding bites. Medical doctors celebrate the contact stethoscope auscultation brings with the patient; most vets prefer to maintain a safe zone.
  • Expense: Veterinary patients are notorious for not respecting boundaries. Electronic stethoscopes and their digital alternatives cost a lot more than a standard manual model. Would I want to brandish hundreds of dollars’ worth of hearing tube wannabe in a muddy farmyard cattle crush, or dangle it over the open ocean? No; nor would my boss be happy with me for risking the practice profits. As a side note, how many clinicians in marginal communities or developing countries can afford more than the perfectly functional basics?
  • Convenience: The alternatives might be hand-held, but they all need power. Where’s the electrical outlet in a remote cow byre? And how many battery changes are required to complete a herd health visit? Just my luck that the battery would fade just as I homed in on a crucial diagnostic squeak in the consulting room. My ears don’t wear out unless they are enjoying a Pet Shop Boys concert.


But am I just being a luddite?

I checked with some of my peers through Facebook. Most of them are still in practice and therefore see life at the sharp end. Would they lose the stethoscope and swap the traditional for digital, I wondered? By Tim1965 [Public domain], via Wikimedia Commons Of the seven who replied, three mentioned that electronic stethoscopes received as gifts remained unopened, unused and unloved. One reason given is that veterinary use is a very small market, and stethoscopes designed for human use, even with pediatric sizing, are often not refined enough for diagnostic work in cats, for example. Three large-animal vets mentioned problems with cost for both maintaining the equipment and dealing with damage or loss in the field.

Q: Just wondering if any large-animal vets would carry around a $350 stethoscope out in the field.

N:  No. We have 45 vets who regularly lose things! And out in the field there is seldom a power source. We power our scanners with good rechargeable batteries, but they are $500 to $800 each.

J: Just the basic stethoscope. Although they will sometimes use their rectal scanner on the chest wall if they think there is a pericardial effusion. All cows.

C: And have left/lost/damaged plenty of kit on farms. … So prob would avoid if expensive.

Only one vet regularly uses the electronic version, commenting that it lasts for ages on a single AA battery. He also mentioned it was a great boost for mild hearing loss, this last point echoed by an internal-medicine teacher at a vet school.

Three vets commented on using scanners as alternatives, with one describing the hand-held option as useful for cage-side assessments but lacking the detail of larger machines. Another mentioned that cattle vets often reach for the rectal scanner when suspicious of pericardial effusion (fluid build-up around the heart)—hand-held yes, but probably not what was envisaged in the articles!

So maybe not such a dinosaur then.


The topic resurfaced again in the last year, with a news story on the CBC/Radio-Canada website and an interview with Dr. Raj Bhardwaj on the Calgary Eyeopener radio program. Dr. Bhardwaj mentions the same high-tech replacements and benefits but does bring up the subject of cost—around $200 will buy you a stethoscope, but you need $8,000 or so for an ultrasound device—and fragility.

Stethoscopes bounce…

…as does the story, which, like the instrument itself, refuses to die.
