#strawfiechallenge – 1 minute of simulated breathing difficulty in recognition of sufferers of cystis fibrosis

Today I’m attaching a clothes peg to my nose and breathing through a straw for 60 seconds. As I won’t be able to talk while I’m doing this, I’ll type an explanation why:

Like most people, I’ve spent most of my life lucky enough to not really know anything about cystic fibrosis. I first really became aware of it when my friend Jen‘s son Lorcán was diagnosed with it (you may remember I shared a video of hers previously).

It’s a lifelong disorder with no known cure.

It’s a genetic disorder, and as many as one in every 25 people carries the gene that can cause it. Inherit two genes and you’re a sufferer. Among other symptoms, it causes frequent lung infections and difficulty breathing.

I’m taking part in the #strawfiechallenge as an exercise in appreciating how difficult it can be to cope with reduced lung function. A new drug, Orkambi, is helping to extend the lives of sufferers in other countries around the world. But it’s not yet available in the UK. :-(

CF sufferers want #OrkambiNow. They need your politicians to act.

100 Years of Periods

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

Bitesize introduction to the (mostly-unspoken) history of the last century of sanitary products. It wasn’t so long ago – still within living memory! – that doctors’ advice was not to exercise during your period and that sanitary products had to be packaged in plain containers so as not to embarrass buyers nor sales assistants. Humans have had a long and complicated relationship with menstruation but the largest and fastest period (no pun intended) of cultural change has been only recently, and we now live in a world divided by a huge diversity of opinion and philosophy on the subject. This video covers only a fraction of the story of the recent (Western) social change, but it’s still a strong reminder of how far we’ve come as a culture.

Alpha-Gal and the Gaia Hypothesis

Ticking Point

An increasing number of people are reportedly suffering from an allergy to the meat and other products of nonhuman mammals, reports Mosaic Science this week, and we’re increasingly confident that the cause is a sensitivity to alpha-gal (Galactose-alpha-1,3-galactose), a carbohydrate produced in the bodies of virtually all mammals except for us and our cousin apes, monkeys, and simians (and one of the reasons you can’t transplant tissue from pigs to humans, for example).

Lone star tick
The lone star tick (You call that a star, tick? Looks like a blob to me!), one of several vectors for alpha-gal sensitivity.

The interesting thing is that the most-common cause of alpha-gal sensitivity appears to be the bite of one of a small number of species of tick. The most-likely hypothesis seems to be that being bitten by such a tick after it’s bitten e.g. deer or cattle may introduce that species’ alpha-gal directly to your bloodstream. This exposure triggers an immune response through all future exposure, even if it’s is more minor, e.g. consuming milk products or even skin contact with an animal.

That’s nuts, isn’t it? The Mosaic Science article describes the reaction of Tami McGraw, whose symptoms began in 2010:

[She] asked her doctor to order a little-known blood test that would show if her immune system was reacting to a component of mammal meat. The test result was so strongly positive, her doctor called her at home to tell her to step away from the stove.

That should have been the end of her problems. Instead it launched her on an odyssey of discovering just how much mammal material is present in everyday life. One time, she took capsules of liquid painkiller and woke up in the middle of the night, itching and covered in hives provoked by the drug’s gelatine covering.

When she bought an unfamiliar lip balm, the lanolin in it made her mouth peel and blister. She planned to spend an afternoon gardening, spreading fertiliser and planting flowers, but passed out on the grass and had to be revived with an EpiPen. She had reacted to manure and bone meal that were enrichments in bagged compost she had bought.

A delicious-looking BLT. Mmm, bacon.
Cats can eat bacon. But some cat owners can’t. More bacon for the cats? The plot thickens. Also: haven’t used this picture in a while, have I?

Of course, this isn’t the only nor even the most-unusual (or most-severe) animal-induced allergy-to-a-different-animal we’re aware of. The hilariously-named but terribly-dangerous Pork-Cat syndrome is caused, though we’re not sure how, by exposure to cats and results in a severe allergy to pork. But what makes alpha-gal sensitivity really interesting is that it’s increasing in frequency at quite a dramatic rate. The culprit? Climate change. Probably.

It’s impossible to talk to physicians encountering alpha-gal cases without hearing that something has changed to make the tick that transmits it more common – even though they don’t know what that something might be.

“Climate change is likely playing a role in the northward expansion,” Ostfeld adds, but acknowledges that we don’t know what else could also be contributing.

Meat Me Half-Way

To take a minor diversion: another article I saw this week was the BBC‘s one on the climate footprint of the food you eat.

BBC graph showing climate impact of common foods. Beef is terrible *unshocker*.
An average serving of beef contributes almost 8kg of greenhouse gases, compared to around 1kg for chicken. Thanks, Beeb (click through for full article).

A little dated, perhaps: I’m sure that nobody needs to be told nowadays that one of the biggest things a Westerner can do to reduce their personal carbon footprint (after from breeding less or not at all, which I maintain is the biggest, or avoiding air travel, which Statto argues for) is to reduce or refrain from consumption of meat (especially pork and beef) and dairy products.

Indeed, environmental impact was the biggest factor in my vegetarianism (now weekday-vegetarianism) for the last eight years, and it’s an outlook that I’ve seen continue to grow in others over the same period.

Seeing these two stories side-by-side in my RSS reader put the Gaia hypothesis in my mind.

SMBC comic frame: "Yeah, I don't buy it. If Earth is self-regulating and alive, why hasn't it produced an immune response against humanity?"
If you want a pop-culture-grade introduction to the Gaia hypothesis in the context of climate change, this SMBC comic does the job, and does so almost with fewer words than this caption explaining that it does so.

If you’re not familiar with the Gaia hypothesis, the basic idea is this: by some mechanism, the Earth and all of the life on it act in synergy to maintain homeostasis. Organisms not only co-evolve with one another but also with the planet itself, affecting their environment in a way that in turn affects their future evolution in a perpetual symbiotic relationship of life and its habitat.

Its advocates point to negative feedback loops in nature such as plankton blooms affecting the weather in ways that inhibit plankton blooms and to simplistic theoretical models like the Daisyworld Simulation (cute video). A minority of its proponents go a step further and describe the Earth’s changes teleologically, implying a conscious Earth with an intention to protect its ecosystems (yes, these hypotheses were born out of the late 1960s, why do you ask?). Regardless, the essence is the same: life’s effect on its environment affects the environment’s hospitality to life, and vice-versa.

There’s an attractive symmetry to it, isn’t there, in light of the growth in alpha-gal allergies? Like:

  1. Yesterday – agriculture, particularly intensive farming of mammals, causes climate change.
  2. Today – climate change causes ticks to spread more-widely and bite more humans.
  3. Tomorrow – tick bites cause humans to consume less products farmed from mammals?
Daisyworld in SimEarth
Both my appreciation and my rejection of Gaia Hypothesis can probably be traced to me playing way too much SimEarth as a teenager. Here’s my Daisyworld in state of equilibrium, because I haven’t yet gotten bored and spawned dinosaurs to eat all of the daisies.

That’s not to say that I buy it, mind. The Gaia hypothesis has a number of problems, and – almost as bad – it encourages a complacent “it’ll all be okay, the Earth will fix itself” mindset to climate change (which, even if it’s true, doesn’t bode well for the humans residing on it).

But it was a fun parallel to land in my news reader this morning, so I thought I’d share it with you. And, by proxy, make you just a little bit warier of ticks than you might have been already. /shudders/

Daily Physio for Cystic Fibrosis

This article is a repost promoting content originally published elsewhere. See more things Dan's reposted.

My friend Jen‘s been blogging and vlogging about cystic fibrosis – which her young son Lorcán has – in order to raise awareness of it and of a promising new treatment, Orkambi, which would very likely dramatically improve the lifespan and health of chidren like Lorcán… were it available on the NHS. For more information, including petitions you can sign, see their blog Little Fierce One.

Into the Lair of the Bladder Monster

Warning: this blog post contains pictures of urine, invasive equipment, and the inside of a bladder. It’s probably safe for all audiences, but you might like to put your glass of apple juice down for a minute or two. The short of it all is that I’m probably healthy.

Since my hospitalisation the other month with a renal system infection, I’ve undergone a series of investigations to try to determine if there’s an underlying reason that I fell ill. As my doctor explained to me, it’s quite possible that what I’d experienced was a random opportunistic infection (perhaps aided by a course of unrelated antibiotics I’d been on earlier this year or by certain lifestyle habits), but if that wasn’t the case – if there were some deeper explanation for my health problems – it was important to find out sooner, rather than later.

A sterile pot full of Dan Q's urine.
I’ve peed in so many little pots over the last few months! If you laid them end-to-end across your kitchen counter, then people would think that you were some kind of weirdo.

Early on I had several ultrasound scans of my bladder (at a number of different times and at a variety of levels of fullness) and one of my kidneys, the latter of which revealed some “minor scarring” of one of them which apparently isn’t something I should be worried about… although I wish they’d started the two-page letter I got with that rather than opening with, effectively, “Contrary to what we told you at the hospital, we did later see something wrong with you…” But still, good to be reassured that this is probably not an issue.

An ultrasound scan of one of my kidneys. Can you tell the sex yet?

More recently, I went to the hospital to have a “flow rate test” and a cystoscopy. The flow rate test involved the most-ghetto looking piece of NHS equipment I’ve ever seen: functionally, it seemed to be little more than a funnel on top of a large measuring beaker, in turn on top of a pressure-sensitive digital scale. The scale was connected up to the only fancy-looking bit of equipment in the room, a graphing printer that output the calculated volume (based on their weight) of the same and, more-importantly, the rate of change: the “flow rate” of the stream of urine.

A stream of urine pours down into a funnel.
I’m right, aren’t I? That’s basically a kitchen funnel, isn’t it?

I suppose one advantage of using equipment like this is that it basically operates itself. Which meant that the nurse was able to give me five seconds worth of instruction and then leave the room, which saved us from our own Britishness forcing us to make small-talk while I urinated in front of her or something. Ultimately, I turned out to be within the range of normalcy here, too, although I was a little disappointed to find that the ward didn’t maintain a daily “score board” of flow rates, as sort-of a science-backed literal pissing contest.

A graphing printer describes Dan Q's urine flow. The 'flow rate' graph shows an initial peak, then a trough, then continues to a higher sustained peak.
Apparently not all men experience that ‘spurt-and-then-full-pressure’ thing you’ll see on the upper graph, when they start to pee, but some of us do, and I’m told it’s perfectly normal. I’m learning so much!

Finally came the cystoscopy, and this was the bit that I’d been most-nervous about. This procedure involves the insertion of a long flexible tube into the urethra at the tip of the penis, under local anasthetic, and pushing it all the way down, through the sphincter, down through the prostate and then back up into the bladder. It’s then used as a channel to pump water into the bladder, filling it to capacity and stretching out the sides, after which the fibreoptic cord (and light) that runs along its length is used to look around inside the bladder to inspect for any of a plethora of different problems.

Cystoscopy equipment, ready for insertion.
You’re going to put that WHERE?

The doctor invited me to watch with him on the monitor, which I initially assumed was because I was clearly interested in everything and kept asking questions, but in hindsight I wonder if it’s just that he – quite rightly – assumed that I might have panicked if I’d have been looking in the direction of the piece of equipment he brought in and jabbed at my penis with. I only looked at it while it was on its way out, and my god its a scary-looking thing: sort of like a cross between a tyre pressure gauge and a blowtorch. The first few inches were painless – the local anasthetic had made me completely numb right up to and including the external sphincter, which is at the base of the penis. However, what I can only assume was the second sphincter complained of the discomfort, and it stung pretty sharply any time the doctor would twist the cystoscope to change the angle of the picture.

View up a urethra, from a cystoscope.
The view as you ‘travel’ up the urethra looks pretty much like I expected. With a motion simulator, it would make a pretty cool ride!

Seeing the inside of your own body is an amazing experience. I mean: it’s not amazing enough to even be worth the experience of a cystoscopy, never mind the illness that in my case preceeded it… but it’s still pretty cool. The ultrasounds were interesting, but there’s nothing quite so immersive as seeing a picture of the inside of your own bladder, gritting your teeth while the doctor points to an indentation and explains that it’s the opening to the ureter that connects to your own left kidney!

Unfortunately I neglected to take my phone into the operating room, having put it into a locker when I changed into a gown, and so I wasn’t able to (as I’d hoped) take photos of the inside of my own bladder. So you’ll have to make do with this video I found, which approximates the experience pretty well. The good news is that there’s probably nothing wrong with me, now that the infection from earlier this year has passed: nothing to suggest that there’s any deeper underlying issue that caused me to get sick, anyway!

The bad news is that while the procedure itself was shorter and more-bearable than I’d expected, the recovery’s been a real drag. A week later, it still hurts a lot to urinate (although I’ve stopped yelping out loud when I do so) and my crotch is still too sore for me to be able to cycle. I’ve also discovered that an errection can be painful enough to wake me up, which is definitely not the most-pleasant way I’ve been roused by a penis. But it’s getting better, day by day, and at least I know for sure that I’m more-or-less “right” in the renal system, now.

The Bladder Monster

As I mentioned last week, I’ve been ill. For those who wanted the grisly details, well: here you go.

Warning: this blog post contains frank subjective descriptions of the symptoms of slightly-icky medical conditions including photographs. It’s probably safe for all audiences, but you might not want to be drinking anything while you read it.

The trouble began, I suppose, about a month and a half ago, when a contracted what seemed to be a minor urinary tract infection. If you’re a woman then, statistically-speaking, I probably don’t need to tell you what that is, but for the benefit of the men: it’s what happens when bacteria (or, sometimes, a fungus or virus) infects the renal system: the kidneys, bladder, ureters, and especially the urethra. It’s not pleasant: it gives you the feeling of needing to pee the whole time, makes it harder to pee, and – when you do – it feels a little bit like you’re piss is made of lava.

Microscope view of infected urine.
This urine contains white blood cells (the big circles) and bacteria (the tiny ‘wormlike’ things). Healthy urine contains little to none of these. Anybody else feel like they’re playing Spore?

Despite it not being common for men (more on that later), I’ve had mild UTIs on a couple of ocassions in my life, and I’d always found that ensuring that I got plenty of water and a full RDA of vitamin C was more than enough to make it clear up all by itself within a couple of days. So that’s what I started doing. But then things took a turn for the worse: I started getting a stabbing pain in my left kidney. Recognising this as being pyelonephritis, I went to the doctor who prescribed me a course of the antibiotic ciprofloxacin. Within a couple of days I was feeling right as rain (of course I continued to finish the course of drugs, although I was interested to see that that advice is starting to become controversial).

Dan and Annabel have a picnic in the park.
Happy, healthy, and out for a picnic. I guess everything turned out okay, right?

Naturally I was a little disappointed when, the week before last, I started getting UTI-like pain again, followed very swiftly this time by pain in my bladder that constantly felt a little like I was recovering from being punched. Back to the doctor I went, where (after the usual tests to work out what the most-likely best-antibiotic to use was) I was prescribed a course of nitrofurantoin. I’d never had this particular drug before, and it wasn’t initially clear which of the escalating ill-effects I was experiencing were symptoms of the infection and which were side-effects of the medication: it started with joint pain, then nausea, then diarrhoea, then a full-on fever. It was at the point that I was fully-clothed in bed, running a temperature and soaked in sweat but still feeling cold and shivering that Ruth called 111, who told her to take me to A&E.

(Which, like her care for me in general, she did fabulously well, except for a little bit where she sort-of ran me over in the car park of the hospital: thankfully some friendly paramedics were standing around and were able to drag me into the building. Anyway, I don’t have much memory of that bit and I certainly don’t have any amusing photos, so I’ll skip over it.)

Dan, shortly before inpatient admission but already recovering from the worst parts of his hospital visit, last week.
Feverish to the point of delirium, I don’t have much recollection of the first few hours(?) in the hospital. But I was alert enough to request that a photo was taken for the inevitable blog post. Ruth, however, insisted upon waiting until I apparently looked a lot less like I was about to die: so here it is!

A few tests later, the medical staff seemed confident that what I was experiencing was not an allergic reaction to the antibiotic (however, I see that they still made a note of it as a risk on my notes!) but was a progression of the infection, which seemed to have crossed over from the tissues of my renal system and into my bloodstream and was now generally causing havoc by attacking the rest of my body. They hooked me up to a drip of an intravenous antibiotic and kept me stocked with painkillers, then sent me up to the urology ward and set me up with a “bed” (urology mostly deals with outpatients, and so my ‘bed’ was actually a trolley, but they wanted to keep me close to the urologists in case of any complications).

The view from my hospital ward window: Oxford city is visible in the distance.
It was only the following morning, with the delirium passed, that I realised that I was on the sixth floor. Looking out of my window, I could just make out the spires of the Bodleian Library in the distance, so I dropped my coworkers an email to apologise for not being on my way there.

A consultant switched me to a week’s course of yet-another different antibiotic – co-amoxiclav – and recommended keeping me in for another night. Now, I think that co-amoxiclav is a really interesting drug, so I’m going to be a bit of a nerd and tell you about that for a bit (I promise we’ll get back to my health in a moment: if you don’t want the science bit, just scroll past the diagrams to the next photo).

Amoxicillin, with lactam ring highlighted.
This is amoxicillin. I’ve highlighted in blue the lactam ring, which is the important bit.

Co-amoxiclav is a mixture of two drugs. The first is the antibiotic amoxicillin. Amoxicillin belongs to a class of antibiotics (which includes penicllin) called β-lactams, which is the most-commonly used family of antibiotics. These antibiotics contain a four-point lactam ‘ring’ (highlighted in blue above), and the way that they work is that this part of the molecule bonds with a particular protein common to all gram-positive bacteria. Normally this protein is responsible for producing peptidoglycan, which is an essential ingredient in the cell walls of these kinds of bacteria, but when it gets locked to a β-lactam ring it stops working. As a result, when the bacterium reproduces the new child doesn’t have a proper cell wall, and can’t survive long in even the least-hostile environments.

Of course, we’re in a medical arms race right now because some of the bacteria which we’re targetting with antibiotics are becoming resistant. And here’s one what that they’re doing so: some of these bacteria have evolved to produce beta-lactamase, also bonds with beta-lactam rings, adding an OH to them and making them useless. Bummer, eh?

Clavulanic acid, with beta-lactam ring highlighted in blue.
And this is clavulanic acid. Recognise that shape on the left-hand side of the molecule (highlighted in blue)? Yup: it’s another lactam ring.

The second drug in co-amoxiclav, then, is clavulanic acid, which was discovered in the 1970s and started being added to drugs in the 1980s. Despite having a β-lactam ring (as you’ll see in blue above), clavulanic acid by itself it isn’t an effective antibiotic (for reasons I can’t quite get my head around – anyone want to help me?). But what it’s great at is bonding that lactam ring to beta-lactamase, thereby deactivating the bacterial counter-offensive and allowing the amoxicillin to carry on working, combating resistance.

So what you’ve got in co-amoxiclav is a an antibiotic and a chemical that counteracts the effects of a chemical that deactivates that antibiotic. Wow! It’s things like this that really make me wish I had a brain for biology!

A cannula in the back of Dan's hand.
These things aren’t terribly comfortable when you’re trying to sleep.

I was eventually discharged from hospital and released to go home for lots of bed rest and water, along with a further week’s course of co-amoxiclav. Unfortunately it turns out that I’m one of the unlucky folks for whom amoxicillin makes me dizzy, so I spent most of that week lying down in-between wobbly vertigo-filled trips to and from the bathroom. But it worked! Within a few days I was feeling much better and by the end of last week I was able to work from home (and actually feel like I was useful again!).

Free of symptoms and off the drugs, I returned to work properly on Monday morning and everything seemed fine. Until, late in the morning, I went to the bathroom and started pissing blood.

A kitten lying on its side.
I took a picture, but it’s too grim even for this blog post. Here, have a kitten instead. Do an image search for ‘gross hematuria’ if you want a clue: the kitten will still be waiting here when you need it.

Now apparently blood in your urine, while horrifying when it happens to you unexpectedly, isn’t actually a sign of a medical emergency. I was starting to get bladder pain again, quite intensely, so I excused myself from work and called the urology ward, who decided that I wasn’t in bad enough a condition to go and see them but sent me straight to my GP, who gave me another fortnight’s worth of co-amoxiclav. They’re monitoring my progress with urine and blood samples and if by Friday it’s not having an impact, they’re going to want to send me back to hospital (hopefully only as an outpatient) and pump me full of the intraveneous stuff again. So… fingers crossed for a good result out of these drugs.

Co-amoxiclav tablet in packaging.
My co-amoxiclav tablets each come individually wrapped in a nitrogen-filled foil bag. I’ve no idea what it is that they’re concerned that they’ll react with, but I’m eating three of them a day anyway.

I was hoping that by this point I’d be writing this blog post and telling you all about how I’d fought the bladder monster and won. But it looks like I won’t be able to claim that victory for another week or two, yet. All I know is that I searched for “bladder monster” and found this. Yeah: that feels about right.

Calculating Pi (when you’re ill)

So, I’ve not been well lately. And because a few days lying on my back with insufficient mental stimulation is a quick route to insanity for me, I’ve been trying to spend my most-conscious moment doing things that keep my brain ticking over. And that’s how I ended up calculating pi.

Dan, shortly before inpatient admission but already recovering from the worst parts of his hospital visit, last week.
When I say I’ve been unwell, that might be an understatement. But we’ll get to that another time.

Pi (or π) is, of course, the ratio of the circumference of a circle to its diameter, for every circle. You’ll probably have learned it in school as 3.14, 3.142, or 3.14159, unless you were one of those creepy kids who tried to memorise a lot more digits. Over the years, we’ve been able to calculate it to increasing precision, and although there’s no practical or theoretical reason that we need to know it beyond the 32 digits worked out by Ludolph van Ceulen in the 16th Century, it’s still a fascinating topic that attracts research and debate.

Graph illustrating the calculation of digits of pi over the millenia. Note the logarithmic scale on the left and the staggered scale on the bottom axis.
Our calculation of pi has rocketed since the development of the digital computer.

Most of the computer-based systems we use today are hard to explain, but there’s a really fun computer-based experimental method that can be used to estimate the value of pi that I’m going to share with you. As I’ve been stuck in bed (and often asleep) for the last few days, I’ve not been able to do much productive work, but I have found myself able to implement an example of how to calculate pi. Recovery like a nerd, am I right?

A "pi pie", from a Pi Day celebration.
Pi goes on forever. Pie, sadly, comes to an end.

Remember in school, when you’ll have learned that the formula to describe a circle (of radius 1) on a cartesian coordinate system is x2 + y2 = 1? Well you can work this backwards, too: if you have a point on a grid, (x,y), then you can tell whether it’s inside or outside that circle. If x2 + y2 < 1, it’s inside, and if x2 + y2 > 1, it’s outside. Meanwhile, the difference between the area of a circle and the area of a square that exactly contains it is π/4.

A circle of radius 1 at the intersection of the axes of a cartesian coordinate system.
Think back to your school days. Ever draw a circle like this? Do the words “cartesian coordinates” ring any bells?

Take those two facts together and you can develop an experimental way to determine pi, called a Monte Carlo method. Take a circle of radius 1 inside a square that exactly contains it. Then randomly choose points within the square. Statistically speaking, these random points have a π/4 chance of occuring within the circle (rather than outside it). So if we take the number of points that lie within the circle, divide that by the total number of points, and then multiply by 4, we should get something that approaches the value of pi. You could even do it by hand!

Output of Dan's demonstration of the Monte Carlo method as used to approximate the value of pi.
I wrote some software to do exactly that. Here’s what it looks like – the red points are inside the circle, and the black points are outside.

The software illustration I’ve written is raw Javascript, HTML, and SVG, and should work in any modern web browser (though it can get a little slow once it’s drawn a few thousand points!). Give it a go, here! When you go to that page, your browser will start drawing dots at random points, colouring them red if the sum of the squares of their coordinates is less than 1, which is the radius of the circle (and the width of the square that encompasses it). As it goes along, it uses the formula I described above to approximate the value of pi. You’ll probably get as far as 3.14 before you get bored, but there’s no reason that this method couldn’t be used to go as far as you like: it’s not the best tool for the job, but it’s super-easy to understand and explain.

Oh, and it’s all completely open-source, so you’re welcome to take it and do with it what you wish. Turn off the graphical output to make it run faster, and see if you can get an accurate approximation to 5 digits of pi! Or slow it down so you can see how the appearance of each and every point affects the calculation. Or adapt it into a teaching tool and show your maths students one way that pi can be derived experimentally. It’s all yours: have fun.

And I’ll update you on my health at some other point.

Guess where I woke up this morning, MegaMasons?

This link was originally posted to /r/MegaMasonsLounge. See more things from Dan's Reddit account.

Dan in hospital

So yeah: that’s not entirely pleasant. A couple of days ago I was diagnosed with what was supposed to be a minor bladder infection and given antibiotics. Then yesterday I became feverish and collapsed. And now I’m in hospital.

But on the upside, they’ve spent all night pumping me full of some kind of intravaenous antibiotic that must be made from like unicorn spunk and leprechaun tears or something because it’s frankly magical: feeling so much better today than yesterday.

Just wanted to say hi. Hi, all!

Health. Food.

I’m pretty sure that an outside observer, given the advance knowledge of this blog post, could easily tell when I’m in the process of getting over an illness just by the food I eat. I’m pretty sure that I have a particular ‘tell’ in the foods I look for when I’m on the cusp of recovering from a cold, like now: or, I suppose, on those rare ocassions that I’ll have drunk enough to be suffering from a hangover.

Take this lunchtime, for example. I’ve been off work for the last couple of days, laid low by what seems to be the very same cold that I was sure I’d dodged when everybody else got it, last month (I blame Annabel, the contagious little beast, who’s particularly keen on shoving her hands into people’s mouths). Today I’m back on my feet, but working from home: I skipped breakfast, but by lunchtime I felt able to face some food, and quickly determined what it was that I really wanted:

From bottom to top: potato waffle, cheese, potato waffle, egg, tomato ketchup.
An egg and cheese wafflestack. If you think it looks calorie-laden and disgusting, then you’re right: but you wouldn’t be saying that if you were recovering from an illness!

Egg & Cheese Wafflestack

Serves: 1 unwell-but-recovering person
Preparation: 15 minutes
Difficulty: if you can’t make this, get the hell out of the kitchen


4 × frozen potato waffles. I’m using Birds Eye ones, but honestly, who can tell the difference?
~ 30g mature cheddar cheese, grated or thinly sliced, brought to room temperature so it melts quickly
2 × eggs
A little vegetable oil
Tomato ketchup (alternatively, brown sauce works well)


Grill the waffles in accordance with the instructions. Meanwhile, fry the two eggs (“sunny side up”: keep the yolk fluid). Assemble in stacks, with each stack consisting of cheese sandwiched between two waffles, topped with an egg and the ketchup. Serve immediately. Eat as quickly as you dare.

So now I’m sitting here eating the taste of delicious recovery, generating 4096-bit strong probable prime numbers (like you do), and reading the feedback on a browser plugin I released recently. And every part of that is a huge improvement upon lying ill in bed.

Cottage Pie

This morning, while picking up my microwavable Cottage Pie from Somerfield (the best microwave meal I’ve ever had – it’s really quite good considering that it’s re-heated mincemeat and dehydrated mashed potato), I noticed a new product – a similar item but in a slightly smaller container, as part of their “So Good” range. Upon examining the back of the packet, I realised that the major differences by weight ratio were that the “So Good” version – apparently better for you – had very slightly less salt, potato and onion, and worcester sauce added. It seems that the biggest reason this new product is better for you than the old one – and worthy of an increased price tag once it’s introductory special offer expires – is that there isn’t so much of it. I’ll be sticking with my normal cottage pie, thanks.

While I’m busy complaining, why is it that I have to work somewhere that’s to the East of where I live, which means that when I cycle to work in the morning the sun is in my eyes, and it’s still blinding me when I cycle back home in the evening? Bring on the winter, I say! Back to the blizzards and the short daylight hours when I was able to cycle both directions in the dark with no lights on. That’s the way forward!
