November 19 is International Toilet Day. That may sound funny, but it is a serious event. It is a day to contemplate what we have and others don’t. As we sit in privacy on our comfortable flush toilets today, it is hard to imagine that a scant two hundred years ago sewage disposal meant emptying chamber pots into the nearest convenient place, which was often the street.
If you were out for a walk in Britain in the 18th century and heard the cry “gardy-loo,” you had better scamper across the street because the contents of a chamber pot were set to be hurled your way from a window. The expression derives from the French “regardez l’eau” and was commonly heard as chambermaids carried out their duties. Some even suggest that the custom of a gentleman walking on the outside when accompanying a lady can be traced to the desire to protect the fair sex from the trajectory of the chamber pot’s contents.
What may be even harder to imagine than the sidestepping of flying fecal matter is that roughly a third of the world’s population today cannot easily sidestep the problems associated with exposure to untreated sewage because of a lack of access to a toilet. As a consequence, diarrheal disease is rampant, killing more children than AIDS, malaria and measles combined. In developing countries a child dies every twenty seconds as a result of poor hygiene. Mahatma Gandhi recognized the problem when he proclaimed in 1925 that “sanitation is more important than independence.”
The invention of the flush toilet and the introduction of plumbing for sewage disposal mark two of the most significant advances in history. Let’s get one of the toilet myths out of the way right away. Contrary to numerous popular accounts, Thomas Crapper did not invent the flush toilet! It is easy to see how connecting his name with the invention would make for a compelling tale, but what we actually have here is a prime example of the classic journalistic foible, “a story that is too good to check.”
Almost all accounts of the Crapper saga claim that a 1969 book by Wallace Reyburn, cleverly titled “Flushed with Pride-The Story of Thomas Crapper” establishes Crapper as the inventor of the flush toilet. Reyburn actually says no such thing. The book is an entertaining celebration of the life and times of Crapper, the man who “revolutionized the nations’ water closets.” Indeed, that he did do. But flush toilets were around long before Thomas Crapper ever got into the game in the 19th century.
The first flush toilet appeared as early as 1700 B.C. The Palace of Knossos on the island of Crete, built around that time featured a toilet with an overhanging cistern that dispensed water when a plug was removed. Curiously it would take another three thousand years until the next step in flushing technology was taken by Sir John Harrington, godson of Queen Elizabeth I. In 1596 Harrington installed a “water closet” in the Royal Palace that featured a pipe fitted with a valve connected to a raised water tank. Opening the valve released the water that would carry waste into a cesspool. Apparently the Queen was not overly pleased with the invention because odours from the cesspool wafted up into the Royal powder room. It would take another couple of centuries before this problem was addressed.
The first patent for a flushing toilet designed to keep sewer gases from seeping back was issued to Alexander Cummings in 1775. Cummings designed a system that allowed some water to remain in the bowl after each flush, preventing the backflow of odours. Joseph Bramah attempted to improve upon this system with a sophisticated valve that was supposed to seal the waste pipe after each flush. While it didn’t work perfectly, Bramah’s toilet was introduced at just the right time because London was beginning to install sewage systems. Some 6000 Bramah toilets soon dotted the city’s landscape. And then about a hundred years later, along came Thomas Crapper.
In 1861 the Thomas Crapper plumbing company opened for business in London. The time was ripe for the sale of plumbing supplies because the need for proper sanitation was being firmly established. A public report issued in the city of Leeds claimed a significantly higher death rate among children who lived in “dirty” streets where sewage flowed openly. And in 1854 physician John Snow had pinpointed the homes in London where someone had contracted cholera during an epidemic and traced the problem to water contaminated with sewage being dispensed from a pump in Broad Street. The need to flush away problems associated with sewage was becoming clear.
There is no question that Crapper made significant improvements in toilet technology. He invented a pull-chain system for flushing, and an air tight seal between the toilet and the floor. Crapper was also responsible for installing plumbing at Westminster Abbey where to this day visitors can view the manhole covers clearly displaying the name “Thomas Crapper Co.” What he was not responsible for was the introduction of the word “crap” into our vocabulary. That term meaning “refuse” predates Crapper by several centuries.
It is virtually impossible to attribute the numerous improvements in toilet technology since Crapper’s time to individuals. There are patents galore for eliminating overflow, reducing water usage, curbing noise, improving waste removal from the side of the bowl, devices to alert night time users if the seat is up and gimmicks to encourage men to aim properly. And the future may belong to toilets equipped with biosensors that automatically monitor urine and feces for health indicators such as sugar and blood. But for now, just think of the amazing technology that allows for the removal of the roughly 200 grams of poo we deposit per person per day. That’s a stunning 600,000 kilos in a city of three million!
So on November 19, as we get comfy on our high tech toilets, ready to flush away the remnants of a scrumptious meal, a roll of soft toilet paper and fragrant soap by our side, let’s give a thought to how we can help those unlucky enough to have been born in a place where “gardy-loo” still rings true.

In my last post I told you that I would reveal the one thing you can do to have a significant, positive and lasting effect on your brain health as you get older. See if you can spot it in the following list:
Ok, that was a trick question. All of these answers are somewhat correct, but I was looking for the “most” correct answer (flashbacks to undergrad, anyone?): Pump some iron.
I realize I sound like a broken record – I’ve already written about how aerobic exercise can promote healthy aging here and here, and I’ve even already written about resistance training, or lifting weights, here.
So why am I at it again? Because it’s important!
I’m fresh out of the 2012 Aging and Society Conference, where researchers came together to discuss what works and what doesn’t when it comes to healthy aging. It turns out everyone pretty much agrees that exercise is hands down the most effective intervention to keep your brain cells happy into old(er) age. All sorts of different types of exercise, ranging from simply walking to attending resistance training classes, are associated with different types of improvements in cognition, memory, and even brain size.
Of course, there are different levels of effort involved with different types of exercise, or even when talking about a single form of exercise. When my friend Jess asks me to go for a walk, she means a power walk: it usually involves going up hills, sweating like a pig (even though pigs, ironically, don’t sweat much), and barely having enough breath for girl talk (though somehow we always seem to find it). When my friend Al and I go for a walk, what he means is a “mosey”: we stop to look at the view, pet the dog, chit chat with strangers, and have more than enough breath for lengthy discussions about life, work, and the possibility of alien lifeforms. When it comes to brain health, whether you’re walking or pumping iron, a little sweating and effort can go a long way. For example, resistance training has been proven to be most effective when the load, or how much weight you are working with, increases over time. So kick the intensity up a notch: there will still be plenty of time for chit chat around a post-exercise, antioxidant-rich mug of matcha (my new obsession – stay tuned).
Now that the obvious has been (re)stated, I want to take this opportunity to discuss the idea that perhaps lifestyle interventions such as exercise could be prescribed by your doctor. We know that exercise can improve cognition in aging but also conditions like depression. Should physicians prescribe lifestyle changes? Or are diet, exercise, and other lifestyle activities choices we should make ourselves? How would you feel if your doctor prescribed you exercise instead of pills? Would you be more motivated to exercise if the prescription came from your doctor instead of from your friendly Internet science blogger? Your thoughts in the comments!

Since I started running (in earnest) a couple of years ago, I’ve been doing what I can to stay motivated. Running is a great sport because 1) it’s cheap 2) you can do it anywhere 3) it’s hard. So, because of #3 I welcome all opportunities to make running fun – and wearing amusing shirts during races seems like as good a strategy as any.
The idea for the “Does my butt look fast in these pants?” shirt came from a sign I saw at a recent marathon. A guy was cheering on the ladies with a homemade sign that read: “Your butt looks fast in those pants!” I laughed so hard it took me a quarter mile to recover. So I shamelessly stole his idea and made a Better Health women’s running shirt out of it. If you think it’s cool and want one too – I’d be happy to print you one. The larger the batch we order, the less expensive it will be.
So if you’re looking for a funny Christmas gift… or if you just want to thwart the race competition by making it impossible for them to pass you without sputtering out a laugh, let me know. Email me if you’d like to order a shirt and we’ll discuss details. My email is: email@example.com (They are made of Nike dry-fit fabric, come in the colors shown only, and are available in Ladies S, M, L – if guys show interest I suppose we could order a run of men’s shirts too?). Let’s prepare to GET BETTER HEALTH this season… and run our way to victory in the battle of the bulge.
If you live in a small town or rural area of the United States, you may have noticed that family doctors are becoming an endangered species. Private and public health insurance reimbursement rates are so low that survival as a solo practitioner (without the economies of scale of a large group practice or hospital system) is next to impossible. Some primary care physicians are staying afloat by refusing to accept insurance – this allows them the freedom to practice medicine that is in the patient’s best interest, rather than tied to reimbursement requirements.
I joined such a practice a few years ago. We make house calls, answer our own phones, solve at least a third of our patients’ problems via phone (we don’t have to make our patients come into the office so that we can bill their insurer for the work we do), and have low overhead because we don’t need to hire a coding and billing team to get our invoices paid. Our patients love the convenience of same day office visits, electronic prescription refills, and us coming to their house or place of business as needed.
Using health insurance to pay for primary care is like buying car insurance for your windshield wipers. The bureaucracy involved raises costs to a ridiculously unreasonable level. I wish that more Americans would decide to pay cash for primary care and buy a high deductible health plan to cover catastrophic events. But until they do, economic pressures will force primary care physicians into hospital systems and large group practices. My friend and fellow blogger Dr. Doug Farrago likens this process to being “assimilated by the Borg.”
Doug offered a challenge to his readers – to customize the definition of Star Trek’s Borg species to today’s healthcare players. I gave it my best shot. Do you have a better version?
Who are the Borg:
The Borg are a collection of alien species that have turned into cybernetic organisms functioning as drones of the collective or the hive. A pseudo-race, dwelling in the Star Trek universe, the Borg take other species by force into the collective and connect them to “the hive mind”; the act is called assimilation and entails violence, abductions, and injections of cybernetic implants. The Borg’s ultimate goal is “achieving perfection”.
My attempt to customize the definition:
Hospitalists are a collection of primary care physicians that have turned into cybernetic organisms functioning as drones of the collective or hive. Hive collective administrators (HCAs), in association with partnered alien species drawn from the insurance industry and government, take other primary care physicians by economic force and connect them to “the hive mind”; the act is called assimilation and entails crippling reimbursement cuts, massive increases in documentation requirements, oppressive professional liability insurance rates, punitive bureaucratic legislation, and threat of imprisonment for failure to adhere to laws that HCA- partnered species interpret however they wish. The HCAs’ ultimate goal is “achieving perfect dependency” first for the drones, then for their patients, so that HCAs and their alien partners will become all powerful – dictating how neighboring species live, breathe, and conduct their affairs. Resistance is futile.
