There is now a cloud appreciation society. You may have heard about it on the radio a few weeks ago. They have named a new cloud — undulus asperatus — from the Latin, which roughly translates as “agitated waves“. And the roughness is what matters. They are highly disturbed, heralding a storm, and yet tend to disperse without one. The pictures above are nothing of the sort: just cumulus or perhaps nearer cumulonimbus.
I’ve looked at clouds from both sides now, and it is true what they say: that some clouds do have a silver lining, though I’m hesitant to agree yet that every one does. More research is needed.
It was sports day when these photos were taken earlier this week, and for the first time in a while it was not rained off, not even just the once. So these clouds were silver-lined if you were the harassed head teacher. But the sun did not shine for the smaller Chip off the Hack who came away with no honours. Last year, if memory serves, he won the egg and spoon race. This year, although the video evidence is incomplete, it does look like he finished the course without dropping the egg once, compared with his fellow competitors who all seemed to have at least one upset. Had the eggs been real, this would have been a feat in itself, but that day it was not the one being measured. Shall I add that the spoons were not institutional dessert spoons of yore, but wooden spoons with barely any dish? Ah well. He is his father’s son.Donate and help me buy back my Fender ('About' tells you why) Tags: asperatus, cloud appreciation society, clouds, cumulonimbus, cumulus, egg and spoon race, fractals, Joni Mitchell, sports day
Eagle-eyed readers will have noticed that today Bryan Appleyard published his long-awaited interview with Art De Vany in The Sunday Times Magazine.
For new subscribers to this blog, Professor De Vany is a long-term advocate of a lifestyle that mimics that of our paleolithic ancestors, at least in terms of diet and exercise. The Knackered Hack has been echoing this approach, with increasing strictness, for well over a year now. Appleyard, who has himself adopted the diet and shed about a stone, noted how vigorous the professor was for a 71-year-old in various domains, about one of which I am myself still gathering data . If the professor’s nocturnal experience can be replicated, then this will probably be the clincher for a lot of people as they realise the value of the paleo diet in helping them with more than just weight-loss.
More seriously, you can’t help but feel pleased that De Vany’s devotion to the study, practice and dissemination of a more natural way of health is getting the recognition that it surely deserves. This is perhaps an important landmark when you consider that it was Nassim Taleb who told me in the same context that press coverage overstates the risk to society of terrorism and understates the risk of insulin insensitivity, so that we wander around with the wrong probabilistic map. Gary Taubes‘ The Diet Delusion gets a mention in the piece too.
One objection that could be raised is that economic pressures might now be pushing people towards a more refined-carb diet because it might appear cheaper. But in my own experience of stress — and there has been no shortage this year with a double bereavement and other tricky family matters to attend to — the cognitive benefits of the paleo lifestyle can also provide a necessary fresh energy and focus to tackle these new challenges. My basic advice would be to avoid “comfort” food at all costs.
I’m reading James Le Fanu‘s book on The Rise and Fall of Modern Medicine at the moment (a tip also from Art’s early blogposts which I’m also in the process of re-reading). Like Taubes, Le Fanu debunks various post-war social and dietary theories of health, particularly with regard to cancer and heart disease. Cancer, Le Fanu says, is best understood as a disease of ageing rather than lifestyle. And yet, in contrast, it’s evident that De Vany (as Appleyard makes clear) is no quack, but someone who has applied the sciences of complexity to a rigorous examination of what we “modern lab-rats” really should be doing to forestall that process of terminal illness. Weight-loss is clearly such a central issue that a diet capable of returning you to your weight when you were 21 must be taken very seriously indeed.
Well, on my desk for a number of weeks (apart from many august tomes that I should have been reading and absorbing) one has stood out. It’s a 1936 children’s book, entitled Uncle Ray’s Story of the Stone-Age People. It looks like it came out just before De Vany was born. It belonged to my father-in-law: himself a sometime professor of mathematics, WHO health statistician, and poet. Alas, it certainly did not encourage him to follow anything like a paleo lifestyle. The one seemingly useful piece of science that the book contains is the suggestion that our ancestors broke the bones of their prey in order to consume the marrow.
Of course, while our diet may have changed a lot in the past 100,000 years (and arguably for the worse), this humble volume would indicate that casual male efforts to combine DIY and childcare have been alarming womankind for millennia with remarkable consistency. A more up-to-date orange-coloured book of Stone Age advice will soon be available here.Donate and help me buy back my Fender ('About' tells you why) Tags: Ancestral Fitness, art-de-vany, Bryan Appleyard, evolutionary fitness, Gary Taubes, Nassim-Taleb, paleo-diet
I had a migraine a few weeks ago. As migraines go it was a breeze, really. There was no piercing headache, just a vice-like tension that I would normally associate with the before- and, to some extent, the after-effects. It was not a muscular tension-headache nor alcohol-related.
I didn’t experience the normal visual aura, but I’m sure it was a migraine because it was preceded by a strange faintness accompanied by shifting vision. I felt funny for most of the following week, then had a severe headache last Friday. The previous day I’d worked out hard in the gym. So I took medical advice. They said it was probably a virus that had triggered the original migraine; it was not surprising for the symptoms to be there a week later. Take paracetamol, they said. You’ll be fine. And so it turned out.
I’ve had one or two really severe migraines, but I’ve been very lucky. Apart from the couple in my teenage years that would conform to the agonising archetype blighting many people’s lives, I’ve been a light sufferer, by any measure. For 10 years of adulthood I had none. Then just a handful with no pattern or recognizable trigger. And some of those were easily knocked on the head by the early ingestion of paracetamol.
Most recently, my first half-marathon triggered one. And after the London marathon in 2005, I succumbed. In both cases my training had been incomplete: I’d overstretched myself. That would constitute a huge stress: an obvious trigger. I’ve wondered too if the demand for calcium/magnesium following that excessive hammering on bones and joints might not have helped. Too much to know.
Because I’ve escaped lightly, my knowledge of the significant progress of migraine science has been almost (but not entirely) non-existent. I noticed only yesterday, for instance, that Oliver Sacks wrote a book called Migraine in 1970 (with a revised edition published in 1992).
But the subject hove back into my view for a couple of reasons recently. I learned, for instance, that migraine as a neurological condition has a close genetic alignment with epilepsy, and that migraine sufferers are more susceptible to background noise; there is a similar phenomenon (which I don’t fully understand) in relation to eyesight.
My late brother suffered from epilepsy. But, because his epilepsy was apparently brought under control by a similar progress of pharmaceutical research, the family had been largely able to forget the underlying seriousness of a condition which reportedly affects 60 million people worldwide; migraine, by contrast, may affect as many as 300 million. The general impression — certainly one that my brother held — was that the major risk to his health came from the long-term effect of such chronic drug dependency on his vital organs. But it seemed that we could feel blessed that it wasn’t a whole lot worse; going back a generation or two, some family members’ lives had been completely wrecked, and this had chronic knock-on consequences for their carers. These days there are still those whose condition does not respond to treatment.
So, when I was researching my earlier post on Didier Sornette and the housing market, I came across a presentation he delivered in Oxford in January. It revealed some of the wider applications of complexity theory beyond the geophysics where Sornette started. In collaboration with several others, Sornette has published a paper or two explaining how the study of data sets of the brain activity of epileptics (specifically those whose condition does not respond to drugs) showed patterns akin to seismic data of earthquake incidence. The hope is that this might lead to some better method of prediction for sufferers.
The maths is rather intimidating and I’ll try to paraphrase the following as I go along, and link to definitions. Fingers crossed:-
That the pdf [probability density function] of SZ [seizure] energies E follows a power law, and more importantly that its exponent is beta almost equal to 2/3 (as for EQ [earthquake]), has far-reaching, statistical-clinical implications: the mean and variance of E are mathematically infinite, which means in practice that the largest SZ in a given time series controls their values (3). As a consequence, variability is dominant and “typical” has no meaning. The energy pdf, and specifically its heavy tail, also suggests an explanation, at a mathematical-conceptual level, for the proclivity and capacity of the human brain to support status epilepticus, a potentially fatal condition characterized by prolonged/frequent SZ during which the brain does not return to its “normal” state, even when SZ activity abates.
Well, I think the key point is ‘variability is dominant and “typical” has no meaning’, which we liberal artists would tend to capture with the expression ‘to be in a constant state of flux’ although that does not quite cover the sense of unbounded potential for an extreme spike. The problem is that we like to convince ourselves that there is some “normal”, some stability. And, on the surface, so it may appear.
And then Sornette explains:-
In seismology, it has been recognized that the many small, undetected EQ provide a major if not dominant contribution to the triggering future of EQ of any size (7). Prolonged recordings of brain cortical electrical activity (ECoG), the equivalent of seismographs, from epileptic humans and animals contain frequent, low intensity, short bursts of abnormal activity unperceived by the patient and observers and interspersed with infrequent, but longer, more widespread, and more intense bursts (convulsions) (4). The SZ-EQ analogy, including the evidence presented here for an inherent capacity of SZ to trigger future SZ, suggest that a workable prediction scheme should use the triggering by, not only past perceived (clinical) SZ, but also the myriad of unperceived (subclinical) abnormal neuronal bursts.
Sornette’s applied work highlights the cross-disciplinary relationship of the science of complexity and reminds us too that some part of our population suffers from extreme non-linearities in their day-to-day lives. And how more vivid can it be, as the picture above shows, than the fractal manifestation that is the migraine aura; when I first used to experience it, it would mark the beginning of hours of debilitation.
Meanwhile, news was reported a few weeks ago that untreatable epilepsy in children responded to a high-fat/low-carbohydrate diet. This is not particularly new. I notice now that Mark’s Daily Apple picked up a Science Daily report back in January to similar effect. Mark was also the original pointer to the picture above (thanks again Mark). So-called ketogenic diets have been known to be effective in treating even the worst sufferers from epilepsy as far back as the 1920s. And I even found a 1910 medical report quoted on a low-carb forum where a doctor had noted high levels of candy consumption among two chronic epileptic sufferers, one adult, one child, he’d been asked to treat. Drug therapies became preferred later because the higher-fat diets were found to be more difficult to follow, ostensibly for cultural reasons. Today there is a shortage of dieticians to help apply what you might call a clinical diet, where each gram of carbohydrate is very closely measured.
Well, it makes more and more sense to me that diet — and our modern carb-laden diet — has much more to answer for than we allow when we think that we are eating a “healthy mixed diet”. But it’s a struggle to remove easy grain-based carbs, and one has to wonder whether it is a sustainable option for the planet as a whole. Since I can afford it, I’m making the switch, but mainly because of the evidence that grains may play a role in activating cancer genes. I can’t ignore those pointers; I’m 43 and since January the oldest surviving member of my immediate family. Both my parents lived ostensibly healthy lives. That alone should predict that at least one would still be with us since my grandmother was alive just 7 years ago at 91.
Because of the complex, fast-moving chain of events that led to my brother’s death in January, it was hard for the surgeons to provide the family with a satisfactory narrative. I missed the chance to speak in person with the clinician; I was racing down the interstate in (melo)dramatic fashion in order to arrive before what turned out to be a technical pronouncement of death. My brother’s state on arrival in hospital the previous day was not materially different from when I arrived 10 minutes after the certification; he was on life-support simply for the purposes of organ-donation.
But that does not matter. What was described was a total neurological event — a seizure that affected all his vital functions. SUDEP — or sudden unexplained death in epilepsy — is what I understand it to have been, although that was not the word the doctor used. Or perhaps it was status epilepticus.
It’s ironic that neither SUDEP nor status epilepticus was something we knew about beforehand, or ever discussed as a possibility within our family. As I said, my brother’s principle pre-occupation in terms of epilepsy-related health (based on counselling I assume he received quite early on in his life) was that his long-term health would be compromised by the medicine he took rather than the diet he was exposed to. I think it made him fatalistic. I have no recollection that a low-carbohydrate diet would have improved his teenage outcomes, and it was something my mother would surely have responded to, had she known.
Later in life, my brother ate a standard North American diet, and there is no suggestion that this was a contributory factor to his SUDEP, but I have to wonder. Not least because the science of low-carb and the science of earthquakes both point to epilepsy from different perspectives. And scientists like Sornette and De Vany are using the same maths across these various domains.
Changing diet may not be a panacea, and I may already have sown the seeds of my own demise, but you don’t not pay into a pension scheme because you didn’t pay in before. That sort of fatalism does lead to literal and metaphorical penury. But above all else, these findings all suggest that a lot more critical reporting should be applied to questions of public health, preventative medicine, exercise, diet fads and even agricultural subsidy. That obviously ain’t happening at the moment. Indeed, the recent coverage of the ketogenic diet in the BBC/Lancet does not consider whether a lower carb diet contributes to a reduced risk of seizure more generally, and therefore might act to forestall a sufferer reaching the kind of tipping point that Sornette’s science is point toward. It is dealt with in the specific of untreatable epilepsy with no extrapolation that more general metabolic risk factors need to be considered or highlighted for all sufferers.
Well, when I asked in one of the leading cookery shops with a vast, if not complete, array of cookery titles if they had anything on the paleo diet, they had no clue what I was talking about, unsurprisingly. So there is much work to be done. That said, Nassim Taleb‘s advocacy in The Sunday Times the other day certainly has led to more Googling of “paleo diet” and other associated terms, from what I can see here, including searches for Prof De Vany.

So, I was fretting about underdogs in the last post. This past weekend, the Sunday Times Magazine ran a long interview with Nassim Taleb in which he was described as “now the hottest thinker in the world”, charging up to $60,000 per speaking engagement, with the great and good beating a path to his door — from the world’s leading banks to NASA.
Interestingly, the interview by Bryan Appleyard included lunch and, naturally, had Nassim following Art De Vany‘s dietary prescriptions of evolutionary fitness. Well, some of my most loyal readers will have heard it here first.
For other reasons (and by accident) I found an old email pitch yesterday that I made in 2003 to a magazine on corporate governance; let’s say this was during my ugly duckling phase:-
Also, I have an interview idea which you might be interested in. Have you heard of a book Fooled By Randomness by Nassim Nicholas Taleb–a maths professor and hedge fund trader from the US? He is in town in a few weeks and I thought I might try and get a hold of him. Although his background is in quantitative trading, he has some interesting things to say about luck and probability in a business context, and it has struck me that this could provide some interesting reflections from a corporate governance point of view. The underlying theme would be that over-remunerating senior executives is even more hazardous than we think if both success and failure may owe more to luck than judgement, backed up by a good dose of sound mathematics of course.
Let me know if you think it a bit too outlandish. My owns sense is that Taleb and others are leading market thinkers and their ideas will permeate downwards in due course.
I didn’t get a commission.
Back in those days, even though Fooled By Randomness was a bestseller, you could still turn up at the now-disappeared Financial World Bookshop in Bishopsgate and hear Taleb talk for nothing to a small and select audience of besuited quants and the odd unshaven, head-scratching scribe. And you try and tell that to the young people of today — will they believe you? No.Donate and help me buy back my Fender ('About' tells you why) Tags: art-de-vany, Bryan Appleyard, corporate governance, evolutionary fitness, Fooled-by-Randomness, Nassim-Taleb, Sunday Times
Great Britain again dominated the World Track Cycling Championship at the Manchester Velodrome this weekend. I watched only briefly, taking a break from the Twitter stream to see an interview with team psychologist Steve Peters.
Peters is something of a phenomenon, if not a genius; Undergraduate Dean of Sheffield University, much in demand in a variety of UK sports, he’s a sometime visitor to the England rugby training camp here at the Sports Training Village in Bath — which, by the way, seemed to be a secret he did not want told on national TV.
But most interestingly, perhaps, he is a former forensic psychologist, who spent many years working in Rampton Secure Hospital, exemplifying our own belief here at Knackered Towers that the study of that which is broken yields useful lessons if you want to succeed.
If that were not enough, the unassuming Dr Peters is a highly competitive Masters M50 sprint champion (that’s running fast for old folks). His training regimen, discussed here, would likely pass muster with that most eminent of critical thinkers on all things sporty, Professor Art de Vany. It’s very unorthodox.
Now, recently I’ve been tempted to comment on Reuters’ CEO Tom Glocer’s blog, but held back. Tom was talking about national character, negativity and optimism. If I understood his point correctly, he was saying that if only you think positively, good things will follow (that was the post title in any event). He referred to the need for an optimistic outlook, drawing on the athletic coach and the self-talking salesman as examples.
You can’t really argue with that. Except that, as Ed Smith painted in his book, the truth is a lot less certain and requires a more subjunctive qualification: think positively and good things might happen. The corollary being, think negatively and it ain’t gonna happen, not now, not never. And that’s more my own experience; as Woody Allen would have it, 80 pct of life is about turning up.
But, in my own corporate experience, positivity and negativity tend to be understood in very binary terms. And because of that, useful information about how products could be improved (or an organization better configured) does not flow freely up the ranks. With tools like wikis, of course, it now flows much more freely across reporting lines, if managers take the step to encourage their use. And it flows pretty freely among the folks who stand outside the office smoking, but let’s not go there.
Returning to individual and team confidence, what Peters had to say was quite brief but highly nuanced. What was clear was that positive thinking, and the psychological tools needed to create it, were not straightforward: they were specific to the individual, but also situational depending on the person, whether a team was involved, the type of event, the coach, championship and location. What mattered was educating athletes into how their minds worked, what trigger points led to negative emotions, and how those could be turned around.
Vicky Pendleton, the diminutive and self-confessed “girly girl” who won two gold medals and a silver over the weekend, had lacked confidence, according to Peters, when he started working with her. But he described how she had been able to train herself to turn her mood around within 10 minutes of a setback.
Peters explained how large events, such as the Olympics, create a huge range of distractions (from transport to security) each of which will affect each athlete differently, and for which all need to be prepared if they are to secure their own best chance of success.
What makes sport an interesting crucible through which to understand performance these days is that there is just so much of it, it is so professional, and there is so much research (physiological, neurological, psychological) . And it produces characters like Peters, Martin O’Neil and Ed Smith.
Sportsmen and women are dealing with the most intense of situations in which their vulnerabilities are very public, even on a day-to-day basis in training. They have a lot of complex information to understand, and failure to self-manage can quickly lead to injury, loss of form, loss of a place on the team, loss of funding, denial of access to quality coaching, etc. And that ignores the consequence of a random fall or illness at a critical moment in a training schedule. This cascade gathers its own momentum because at each stage the athlete finds him or herself increasingly isolated, so the reversal becomes commensurately difficult to effect.
It should not be forgotten, and if you have ever trained really hard you will know, that resulting sharp mood swings can affect motivations and relationships outside of the sport as the body and mind adapt and recover from the process of extreme exertion. Indeed, a protracted bad mood is a sign of over-training syndrome which is very hard to pinpoint in oneself until it’s too late, and takes a surprisingly long time to recover from.
There don’t seem to be enough Steve Peters to go round sport, let alone international business. I wonder how we should go about making more?
