Blue skies and bike seats

Image of pigeons wheeling, silhouetted, after afternoon prayers, above the Jama Masjid in the old town of New Delhi against an impossibly blue and bright sky.
Dear Gentle Reader,

Blue skies are apparently ahead.

Which would be good, as storm clouds have raged, or, worse, droned for a while.

For anyone who actually ever checks over here, yet another mea culpa.

The past couple of years have been a bit trying, medically, as interesting diagnoses come and go.

Parkinson's disease one day.

Multiple sclerosis, another.

Fortunately, both of those were rejected after extensive testing.

Unfortunately, the underlying conditions were ultimately described as a syndrome; diagnostic shorthand for "we know what symptoms you present, and they are real, but we have no idea what the underlying cause is, or how, ultimately, to treat you".

Great.
Really.

I really didn't want Parkinson's, or MS, true.

And I really didn't want the underlying conditions, either.

Another set of conditions were ultimately resolved in a similar way--by calling them a syndrome, again.

Which was all sort of fine.
Ish.

Until, rather recently, there was another concern.

Doctors thought that I might have pancreatic cancer.

And pancreatic cancer is really not good.

Whilst life is terminal (we ride a sinking boat from birth, to paraphrase some Buddhists), pancreatic cancer tends to accelerate the submersion like a torpedo hitting amidship.

Pancreatic cancer led to an extensive pharmacological diet aimed at whacking me in the belly--amidship my ship.

Now, for your humble scribe, pharmacological diets can be rather interesting, and not just amidship. My upper decks and command centres take hits of their own.

Fermented sugar, alone, has interesting effects while stronger pharmawonders tend to bend the hues of the spectrum and provide organic whammy bars to your humble scribe's sensory interpretation systems...

(Your humble scribe hallucinates, visually and aurally (hypnogogic hallucinations), upon taking Tylenol 3s, which my Southern Cousins would call Tylenol with Codeine... ...most people take Tylenol 3s with much less ado simply for pain relief.)

...But, my big pharma anti-pancreatic cancer diet held new combinatorial side-effects for my pleasure and enjoyment...

...such as autodigestion of my cartilage and tendons...
(...mmm...)

...and total-body tendonitis...
(...woohoo).

And then, just before I took off to India, I was told that pancreatic cancer was not, in fact, a concern.

Presumably a new syndrome diagnosis will be offered to me to replace the diagnosis taken away from me but, again, I am rather fine with this.

I still have a pharma diet, which is a much reduced pharma diet from my 'peak', which is good (ish) though I've only managed two non-pharma meals in the last seven days...

(And yet those love handles still persist!)

(...Do you actually have to want to be an ascetic (rather than being forced into asceticism) to get those sveltish lines of Siddhartha Gautama, post his "Great Departure" (when he left his Father's kingdom, and luxury, to live life as an ascetic)?)

Anyway.

All this is by way of an explanation for my absence, as I had promised a few people that I would write, ages ago.

And then broke those promises.

Now you know why.

Anyway, enough whining.

I've been gone a rather long time; I am trying to get back onto the saddle.

I hope to write more soon, and maybe even read.

Till then...

3WW CLXXXI (3WW3)

Detail of a stained glass window from a Church in Normandy. From Caen, I believe.
Dear Gentle Reader,

It's 3WW time, again.

This week the prompt words for prose or poetry are pulse, shard, and weary.

Your starter is a titled picture with, as always, descriptions if you run your mouse over the image.

Then, as usual, I serve up three haiku/senryu, each with an American Sentence title.

For dessert, a musical offering.

If you're like me, have dessert first and enjoy it while reading.

So, away.

I have to get back to packing.

We are in the midst of moving and we have too much stuff.

So, sorry if I try to store some words here, on the web, but there is no room in the stables tonight...

And, with that, let the games begin with pulse, shard, and weary...



On safari, the carnivore rules over all--- ROWRRR... (sob) ...CruNCH ... ... ... ... ... ... (...no pulse...)

shards of meat (and bone)
but, no pulse (legume, bean, pea)
weary vegan pales...





The origin of glass, a Western, or a Near (not Far) Eastern, tale...

Pliny's Phoenicians
found proto-shards where weary
sailors' fires throbbed, pulsed.



What is this poem all about?

Well, Gentle Reader, a circuitous explanation ensues. Sorry.

You ought to know, by now, that your humble scribe is (currently) based in Hong Kong.

Hong Kong is right beside China.

Hong Kong is even in China, if you believe the Mainlanders rather than your visa requirements.

Hong Kong is certainly within the media orbit of modern China.

Recent Chinese 'historical' pop culture movies (Red Cliff, for example) extol the fact that ancient China invented almost everything.

Like soccer. (A specious claim, at best).

Your humble scribe and Heroine find themselves amused to note that almost all things are Chinese these days.

Soccer/football?
Surely Chinese.

CERN and the Higgs Boson?
Surely Chinese.

The alphabet?
Mmmhmm.

Crime?
Vice? ...

...Well, those are obviously foreign.

...Especially when you read or hear the news, in China...

But, glass?
The beach at Mont St-Michel, Normandy, France, as seen through transfigured beach... the medieval glass of Mont St-Michel

Glass is definitely not Chinese.

Glass is one of those areas where, if you are a Westerner, you can hold your head high on the origins of innovation front because the ancient Chinese did not invent glass.

The Chinese 'discovered' glass only from overland traders sometime in the end of the Spring and Autumn period of Chinese dynastic history (770 BC - 476 BC) or in the beginning of the Warring States period (475 BC - 221 BC).

Pliny the Elder (23-79), however, gives us the historic/mythic origin theory that Phoenician sailors (Phoenicians are those Fertile Crescent trading folks whom most Lebanese claim as their forebears) discovered glass sometime around 5000 BC.

Pliny's Phoenician sailors/merchants were cooking their meal of reconstituted pulses in pots over fires on the beach as they rested their weary bodies...

Those Phoenician pots, in turn, while cooking the pulses, rested upon blocks of nitrates which the sailors/merchants were carrying.

And, as those blocks of nitrate melted, from the heat of cooking fires, the melted nitrate fused with silica, the sand on the beach, to form 'ur-glass'--the original man-made glass.

This originating glass was not only clear(ish) but, when the half-melted nitrate trading blocks were forcibly removed, this proto-glass would have resolved into shards of glass...

...which would have engrossed the attention of sailors, weariness forgotten, with sharp shards of a novel, transparent solid in front of them and their bellies full of reconstituted pulses.

See how easy this fit into today's 3WW words?

3WW even allowed me to point out Western technical/innovation prowess.

Even Mesopotamian prowess.

For, despite Pliny's tale of the Phoenicans of around 5000 BC, the first archaeological record of glass comes to us from pre-Bronze Age Mesopotamia--from the pre-Sumerian Uruk Period (4000 BC - 3100 BC ).

Sure, this is almost a thousand years before my beloved Akkadians spring to prominence in Mesopotamia, but, for once, I can write about something that was not invented first in China.

Thanks, Thom (Keeper of 3WW and provisioner of words).

Words like these make my day.

(Although, Thom, I would love the challenge of an x, y and z themed 3WW, too--as you suggested on your prompt page...)






To the victors go the spoils, and thanks, of royalty; to the writers...

pusillanimous;
lacking heroes' pulse, courage.
Weary shards of men...



(Of course, today, the writers get royalties.

But, not if they publishes on the web...)




There you go, hepcats.

Maybe when I am less bone weary the haiku will pop out easier.

Tonight, well, this is better than nought.

I hope.



Tschuess,
Chris

3WW CLXXVII

Image of a bouquet of roses, made from some foamed plastic, with glowing snippets of fibre optic cable sticking out. This image is titled 'Alien Bouquet hot from Victoria Park's Chinese New Year Fair (Hong Kong, 2010)'Dear Gentle Reader,

It is 3WW. Again.

Not so much love for my loose id postscript for last week's 3WW, but I take what I get, and I did like what I did receive. (What a suck, no?)

Anyway, thanks are due to Thom, as usual.

This week the 3WW word prompts are occur, ragged, and tidy.

As usual, I present three haiku/senryu, each with an American Sentence title.

So, let the games begin with occur, ragged, and tidy....

OH! You might note that I have gone with aural interpretations of the words, and visual sleight-of-hand, too, just for fun. (Mine.)

And, lastly, the Heroine of this site recommended that folks read the green explanations under two of the poems... ...and, without further adieu...


William shakes fist, spear; shivers the air with his tempestuous anger...

Oh cur! Oh ragged
Cur! Hang cur! Hang you whoreson...
[Tidy curse for foes!]


**The Tempest, Act 1, Scene 1
Antonio: "Hang cur! Hang, you whoreson, insolent noisemaker!"
William Shakespeare (1564-1616)






In soft, modern days and ages the old lives on, even if not here...

(D)ragged over thresholds--
out of tidy home to hell;
forced weddings occur.






To test his theory the new priest undressed her, removed her rags, and then...

Tidy ochre scraps
swept into neat piles by priest.
D-ragged... ...Mummy gone...


**Mummies, those fabulous Egyptians whose bodies were rendered less mortal, ultimately derive their name from bitumen, a heavy petroleum product, once worked into devotional art by the Medes, early Persians, and by others.

It was believed, from the colour of the preserved corpses, that bitumen, mum in Persian, thence mumia in Latin, thence Mummy in English, had been used in the mummification process.

The modern priestly caste, sometimes known as scientists, de-ragged, or removed the wrappings on the corpses--the Mummies--to check, and found no trace of bitumen in the Mummies' corpses.... so, linguistically, the Mummy was a Mummy no more (no bitumen).



Tschuess,
Chris


PS. As an aside the baroque musical style 'Ciaccona', possibly more familiar to most through its French name, chaconne, always reminds me of modern dance music; it has a driving bass line with a series of short harmonic variations which dance around that beat. I enjoy dance music (I enjoy dancing) and tend not to be too epochcentric... Hopefully some of you will enjoy this selection.

(Admittedly, the beat per minute rate of this Ciaccona is slower than most modern dance and electronic music, but most ravers and dubsteppers are wearing clothing easily weighed in micrograms, not the kilograms of baroque outfits, not to mention those Lady GaGa-esque baroque wigs...)

On poison, fugu, pufferfish, and tetrodotoxin

An image of a porcupine fish used as a lantern at your humble scribe's abode, entitled 'Death incarnate. Or his cousin.'.Dear Gentle Reader,

You're back!

I wasn't sure you'd return.

Care for some wine?

A taste of the goodness in Borgia's cup, perhaps?

No, today there will be no drinking. We don't want to gag.

Only solid(ish) food, today.

And a tale from the field.

Monday's image was a close-up section of today's image which shows a lantern in your humble scribe and Heroine's home, made from a fish.

This fish is not the fabled fugu, the pufferfish.

This is its cousin, the porcupine fish, a blowfish.

Both fish blow or puff themselves up, but blowfish have huge, very conspicuous spines studding their body, whilst pufferfish have much smaller, more slender, delicate spines.

Both, mind you, are well-equipped, internally, with tetrodotoxin, sometimes known as TTX.

Tetrodotoxin, C
11H17N3O8, has a really fancy IUPAC name:
Image of tetrodotoxin, TTX, sourced from the Wikimedia Commons; in the public domain.Octahydro-12-(hydroxymethyl)-2-imino-5,9:7,10a-dimethano-10aH-[1,3]dioxocino[6,5-d]pyrimidine-4,7,10,11,12-pentol.

Try dropping that in conversation.

Just don't drop it in the wine. Or in the food.

Unless you want to best the Borgia's and their relatively tame cantarella, by comparison, at least.

There is no known antidote to TTX; no known cure. And the puffer fish, specifically Takifugu rubripes, the torafugu, is the second-most poisonous vertebrate on planet Earth.

What does tetrodotoxin do?

Well, it's a bit like that hemlock that Socrates drank.

TTX paralyzes you and then you drown in the fluid that accumulates in your lungs.

But, TTX does so much more than that. It shuts everything down, except that, usually, you are lucid right until the end. Although you might feel a floaty sensation and a few other tricks of the mind.

TTX is a neurotoxin which blocks sodium transport channels for your nerves--it stops your nerves from working.

People with multiple sclerosis, for example, have damaged myelin sheathes, the insulation around the electrical lines in our bodies that we call nerves.

When the myelin sheath is damaged the electrical differential across the nerve diminish and there no longer is enough of a differential to reliably push signals around the body.

So, people in later stages of multiple sclerosis find that their body stutters around like a car engine trying to start with a dead battery.

The neurotoxin TTX doesn't just diminish the electrical differential, however, it stops it.

If there is only a little bit of toxin, your body might process it before you die.

You have 24 hours to live. Live that long and you keep on living.

If not... you don't need to worry about whether you left the lights on; your's will be out.

And not much TTX is needed. Based upon the Sigma-Aldrich (a chemical supply company) Material Safety Data Sheet for TTX it can be calculated that 25 milligrams (0.000881 oz) of tetrodotoxin would be enough to kill a 75 kg (170 lb) person who consumed that much TTX orally.

If TTX was injected into you, say via a pufferfish or blowfish spine, then around half a milligram (0.00002 oz) of TTX would likely do you in.

If you're lucky. though, and survive 24 hours, then you are fine.

Some researchers think that the poison accumulates in pufferfish and blowfish due to a bacteria which they harbour. Others think that TTX is generated by the fish themselves.

An engineer would say... who cares? The fish kills.

The gourmet, however, says... I wonder what it tastes like?

Which was my reaction, years and years ago, on my first encounter, on a two week canoe trip in the Northern reaches of Saskatchewan, on seeing poisonous hemlock. The stuff that killed Socrates.

"I wonder what it tastes like?" I said as I reached out to touch the stuff that had killed Socrates.

And then I reached back to hold my head where the guide, who was in my canoe, had walloped the back of my head with his paddle. (The square root of 64....7?)

I still don't know what hemlock tastes like... nor what the square root of 64 is...

You have no idea how curious I am, too... regarding the taste...

Anyway, back to the pufferfish and to the blowfish.

Handling those fish is tricky.

Filleting one of those fish is also tricky.

Most of the poison is in the organs on the inside, especially in the liver.

One slip of the knife, into an organ, and the poison comes, with the knife, back through the flesh.

Then the eater will likely be dead.

And the chef will be out a job.

My lantern is from the body of a porcupine fish, a blowfish--the one with the bigger spines; it's easier to handle than a pufferfish.

Not only that, but there is slightly less poison in a blowfish than in a pufferfish.

What does that information tell you?

It tells you that if you are going to go to the effort to find and eat one of these fishes, make sure you eat the pufferfish. It's more dangerous and more deadly.

Go for Takifugu rubripes, the torafugu; it's the deadliest and the most expensive.

Only specially trained chefs can prepare and serve fugu in Japan. And it can be quite expensive.

Even when your humble scribe lived in Japan, he never ate it. His girlfriend at the time was against it.

But, like the hemlock, he always wanted to know what it tasted like.

When I lived in Taiwan, I went on an expedition to Penghu (澎湖群島), the archipelago of Taiwanese fishing islands far off the west coast of Northern Taiwan, and very close to Mainland China.

The Portugese called these islands the Pescadores because of the fisherman there and the Portugese found this to be a good place to revictual their ships on their way to the Spice Islands.

The Pescadores were well named; they are excellent for fish and for fishermen.

And, it turns out, for fishermens' daughters.

I found myself in the village headmaster and headfisherman's home.

His daughter had dragged me there and I quite happily went; I knew the food would be fresh.

An aside, I never learned any Taiwanese, besides "I'm full", when I lived in Taiwan.

I could understand some Mandarin, but Taiwanese was completely outside my linguistic abilities.

So, while the girl I was with spoke Mandarin, it never occurred to me that her family would not speak Mandarin.

They only spoke Taiwanese.

The father had invited me, I think, to go out onto the boat all day, that morning.

One look at the choppy waves out the window and I knew that fishing was not in the cards. This girl was great, but she was not the one, and I was not about to slam up and down on that surf.

I wanted to enjoy future dinners, not relive past ones.

Besides, this was my opportunity to hang out in the kitchen with a woman who had cooked seafood her entire life. There would be much I could learn, even if it was all delivered in rapid Taiwanese by someone who still looked astonished that a man would want to hang out in her kitchen.

So be it.

The room had concrete walls, low, squat, snug, and capable of keeping howling typhoons out when typhoons would blow over the island.

The windows were small and shuttered; the light was poor and particles of fat from the morning's cooking hung in the air as they oh-so-slowly coalesced on every surface.

The floor was concrete covered in a peeling linoleum that was curling at the edges. It would have been good for quick cleaning of fish guts with a bucket of water, once.

A small, chipped formica table was the centrepiece of the room, and a hefty round of wood was on that table.

That wood, with deep grooves from countless passes of the knife, was the cutting stump--board or block would be totally unacceptable descriptions for this chunk of tree.

At a glance you could tell where, on the surface, various cutting operations had taken place over the years which was good because direct observation was impossible.

The cooking knife, one singular knife, a fairly hefty cleaver with rust on its thick spine but a wickedly glittering cutting edge, sharpened daily, moved like the wind.

Watching this woman was watching an artisan with decades of experience and generations of learning, but I had no idea what she was doing, or even what she had just done, at any given moment. My knowledge of the knife and its purpose was Heisenbergian at best.

Her craft was one to be learned from the crib, by osmosis.

Nothing was explained; she just had a conversation with me the whole morning. Or, really, with herself.

I never had a clue what she was saying or asking. I just smiled and, eventually, had my own conversation with myself, out loud, in return.

At some point in time the girl woke up and sauntered into the room, surprised that I hadn't left with her Pa on the boat.

But, I'd seen his gaffing stick.

I knew where it was safe, although I would never say that.

Shortly afterwards, she obviously knew the rhythm of the home, her Pa came home. It hadn't been a long trip; I would have been fine. But, how was I to know?

Anyway, Pa strolled into the kitchen, with his rolling gait, and dropped a big bucket of fish, still alive and swimming, onto the table for his wife to prepare, presumably for lunch.

If I hadn't thought his daughter was 'the one' for me, before, it was also obvious that he didn't think I was 'the one', either. But, appearances had to be preserved.

I looked inside the bucket.

Baby octopi filled it.

And little pufferfish.

Pufferfish that looked a lot like Takifugu rubripes, the torafugu.

Wow!

This was going to be great.

Then the preparation began.

First, the mother dipped her hands into the bucket of sea water, pulled up most of the octopi, and dropped them onto the chopping block.

Then she turned and started talking to her husband.

It sounded like she was arguing, but Chinese can sound that way.

The baby octopi, unhappy at finding themselves out of water, were squiggling to the edge of the block, then falling onto the formica table, and spreading out on a mistaken theory that she couldn't get all of them and that some of them would escape.

An aside. If you scuba dive you know that octopi are actually quite shy.


Like a family dog.

They remember you.

I've always had dogs.

I've always remembered my dogs and they've always remembered me.

And I don't eat them.

I eat octopi, but not the ones that I play with when scuba diving.

Watching the octopi kaleidescope themselves around the table was a bit like playing with them.

Except that they were fleeing for their lives.

I was trying to figure out how many I could save and release.

Then the mother turned around, picked up the knife, and decimated the class of octopi as they pirouetted away.

(If fish form schools then the more intelligent octopi must be in classes. You heard it here, first.)

Now I knew why the formica table was so pitted and gashed.

She pointed to the site of the octopi massacre and handed me a plate. I put the grey limbs of the octopi onto the plate as I surreptiously picked out a few bits of formica.

Interestingly, for those who don't live by the sea, octopi are a healthy pinky purpley colour. Until you chop a bit off of them. The second you chop a tentacle off that tentacle becomes grey. Instantly.

I tried to work out the rate of change and the mechanism by watching the main body of each octopi change to grey more slowly in contrast to the instantly grey limbs. Then I realized that the limbs were instantly 'dead' whereas the little baby bodies were dying more slowly of blood loss and oxygen deprivation.

Great. There goes the appetite.

And I can see that Pa brought extra octopi after my capacious belly display of the previous evening.

Fantastic.

As I was doing this, I was thinking about the pufferfish. Or, rather, of the fish that looked like pufferfish.

I know that nobody handles pufferfish in Japan with their bare hands.

People use very thick, special gloves.

And this lady had just dipped her hands in amongst the startled, puffed up pufferfish to grab the octopi.

Damn.

These might not be the real things.

Then, to prove a point, she started to grab pufferfish from the bucket, clean them on that formica table, and fillet them on that big uneven block. With her bare hands. Without looking.

That vorpal blade went snicker-snack. She left them dead, and, with their head, she went galumphing back.

And that lady looked at me the whole time, and carried on her conversation.

So these definitely were not 'real' pufferfish.

Shortly afterwards, her husband and both daughters came into the kitchen.

We all crowded around the table eating fresh octopi dipped in some sauce she had made earlier, and slices of raw not-real-pufferfish.

I tried desperately to follow the dynamics, figure out what was expected of me, figure out which sauce was to go where, and to keep the wandering hand of the daughter at bay as her frankly terrifying father glared at me and sharpened a fearsome fishing blade between using his chopsticks to eat the fish.

I was getting pretty apprehensive about her Pa; he was really giving me the willies.

That knife was giving me the willies, too.

Pa took very few octopi, indicating that there were more for me and that, as the honoured guest, I should be eating up. Or was I trying to let him know that this was not good enough for me?

I don't speak Taiwanese, but some things you just figure out.

Great.

Come here boy.

Woof.

Chew.

Mmmm...

Puppy octopi.

...This was really starting to get to me.

Throughout all this I kept eating the faux pufferfish, trying to make sense of everything going on around me.

I was feeling a bit light-headed from everything going on, not quite dizzy, but almost floaty.

And then I poked the back of my mouth with my chopsticks--hard.

Which is something that you really shouldn't do.

It would be like jabbing the tines of your fork into the back of your throat; bad form.

What type of barbarian can't even use eating utensils?

And then I realized that I couldn't feel my lips.

Or my mouth.

Or my tongue.

Or my neck or shoulders.

And there was a fast, slick, creeping sensation, like a swift slug sliding up towards my eyes, and wiping out my ability to sense anything or feel anything.

That's when I realized that the pufferfish was real.

I also realized that I had a chunk of fish somewhere right beside my trachea, although I couldn't feel a thing.

Like a bit of a madman I forced my lungs to exhale and sent a chunk of fish flying.

Onto Pa.

Who was in mid-stroke of sharpening that blade.

And I gesticulated, as best I could, as my anxiety rose while that invisible slug stole all sensations from me.

...

Well, obviously I survived.

And my paranoia and apprehension, it turns out, were side symptoms of the early stages of pufferfish/TTX poisoning.

And the whole family, apparently, all liked me a lot, especially how attentive I seemed to be to everything, even if our ability to communicate was nil, and even if I was a wimp for sitting in the kitchen rather than going onto the boat.

As to what fugu tastes like? That special Takifugu rubripes, the torafugu?

I haven't a clue.

I didn't think it was real fugu--I was trying to figure out what was going on.

And my tongue and nasal cavity were the first things to be affected.

...Next time...
