Stress

Jane Matera is a counsellor with Diabetes UK and she writes an interesting article in the charity’s latest magazine about her theory that type 2 Diabetes is often triggered by people not dealing sufficiently well with the stresses of life.

I’m not going to delve into that subject here – I’m hardly qualified to do so, except by having type 2 Diabetes myself. What interested me as much in Matera’s article is that she actually spells out the stresses we face in modern life compared with earlier generations. Not a surprising list but interesting to see it gathered together in one place.

Humans have always had stress. The hormones involved in the fight or flight response protected early humans from the dangers of the prehistoric world. Some degree of stress is creative, stimulating and necessary to a life fully lived. But […] our bodies are only equipped to cope with short bursts during periods of acute danger.

In our society, I feel there are many everyday stresses that might have been unthinkable 50 – or even 10 or 20 – years ago. They are accepted as immutable facts of life [and] not challenged or much discussed.

This normalisation means we maybe living for long periods […] at a level of stress […] considerably too high for our minds and bodies to safely cope with. And this is at a time when the traditional human support structures – such as the community, work security, the extended family, stable relationships and religious faith – have changed, been depleted or are not available to us.

Common modem stresses that have been normalised include:

  • long-distance commutes, either through heavy traffic or at the mercy of public transport when we are most tired and vulnerable, either at the too – early start or exhausted end of the day
  • the working world of short-term contracts, constant appraisal and machine-led environments may seem practical and economical but can take a human toll
  • the pressure on mothers of even young children to work outside the home to meet the demands of an inflated mortgage
  • mechanisation, which means humans are forced to adopt methods of communication and behaviour dictated by the machine rather than those that are innate
  • mobile phones, iPods, ATMs, etc., disconnect the individual from human contact
  • the fear of a terrorist attack – not a new phenomenon, but one that seems intensified of late in urban areas
  • the completely rational fear of air travel, which is seen as neurotic because of its ubiquity.

How do we fix it? Unless there is a paradigm shift in society and the way our economy works sadly I suspect all we can do is to mitigate these stresses in ways which work for us individually. And hope this is enough to keep Diabetes – and depression – at bay. I see no magic panacea.

Food for thought.

Redesign of Farming

Some weeks ago I wrote about an article in Focus (a UK popular science magazine) about what some see as the pressing need to redesign our farming paradigm (see here). I was heartened over the weekend to see that several luminaries, including Professor Tim Lang, have taken up the cause in the RSA‘s quarterly journal – albeit in a more measured way, but that’s as one would expect from such an august institution. The gloss to their article, The root of the problem, reads:

Food security has risen up the political agenda, but sufficiency of supply is not the whole challenge […] Instead, we should look at ‘food capacity’ and the sustainability of our models of production and consumption.

Good to see the issue is climbing up the agenda. All we have to do now is get agribusiness and our vested-interest politicians to take note.

Papal Carbon Offset

The BBC is running on BBC4 TV a short series of programmes about medieval times. It started this evening with a program in which the comic actor Stephen Frye looked at Gutenberg and the development of the printing press. It was a coffee table programme: long on visual imagery, Frye’s idiosyncratic style and hammed-up wonderment; but despite the reconstruction of a Gutenberg press short on real academic detail. Certainly worth watching and much better than the average run of what these days passes for heavyweight programming; and mercifully devoid of dramatised reconstruction.

Frye made one interesting point, however. The Papal Indulgence was the medieval equivalent of our modern-day carbon off-set schemes: the payment of money to absolve us of our sins. Pure genius. Pure scams.

Perspective

The BBC reports today that Zimbabwe’s President (aka. dictator), Robert Mugabe, has described UK Prime Minister Gordon Brown as ‘a little tiny dot on this world’. Much as it pains me, for once I have to agree with Mugabe.

In the same report South African President Thabo Mbeki said there was “no crisis” in Zimbabwe. Hmmm. I think that makes it fairly clear which mast his colours are nailed to. I’ve been saying for years that South Africa will degenerate into a blood bath; I suspect the only reason it hasn’t yet done so is because Nelson Mandela still has a lot of influence behind the scenes. But once Mandela dies I have a horrid feeling South Africa will go much the same way as Zimbabwe, Uganda, and others. Let’s hope I’m wrong.

Heathrow Luggage Mountain

Absolutely unbelievable!

According to this BBC News item there are now at least 15,000 (and maybe 20,000) pieces of luggage now stranded at Heathrow Airport’s brand spanking new Terminal 5.

And for a third day BA have cancelled around 20% of their flights out of Heathrow with many more apparently leaving without any luggage loaded.

What an unbelievable shambles.

When BA and BAA file for bankruptcy I wonder if the government will have the gall to pay off their shareholders? They’d just better not even think about it!

Yo, Ho, Ho and a Bottle of Duty Free

So after less than one day Heathrow’s sparkling new Terminal 5 has ground to a halt, despite all the much trumpeted testing which was done on the systems using thousands of volunteer members of the public. BAA and the staff appear to be blaming a crap luggage conveyor system. BA are blaming problems with “staff familiarisation”. That’s right; let’s blame the staff when our shiny new technology doesn’t work. Talk about appalling management; I was always taught that the first thing you do is defend your staff publicly (whatever you may have to do behind closed doors) – but that clearly isn’t good enough for BA.

Oh and all this after BAA has been forced to suspend it’s plan to fingerprint every passenger using T5 because the Office of the Information Commissioner says it’s illegal. And why were they going to thus abuse our civil liberties? Because they have been stupid enough to build T5 such that international and domestic passengers (aka. terrorists) can mingle after security checks and could swap boarding passes!

I wonder why I won’t be flying BA any more?

Super-Cows and the Redesign of Farming

I always see Focus, the BBC’s science and technology magazine, and mostly I find it too superficial to satisfy to my scientific mind (not surprising really, it’s designed for interested amateurs, not former science professionals). But occasionally they have an interesting and thought-provoking article or comment. One such is in the current issue (April 2008) where Colin Tudge, zoologist, science writer and broadcaster, makes the case for the redesign of farming rather than the current trend towards super-livestock. Unfortunately the BBC doesn’t put the whole of the printed magazine online, so here is a heavily edited (but I hope undistorted) version of Tudge’s article; to read the whole thing you’ll have to buy the magazine.

The US government has approved the cloning of high-performance cattle, pigs, and goats … The idea is to make genetic copies of ‘elite’ animals: the ones that grow quickest, or give the most milk … Commercially, this sounds good.

But the decision … has been met with protest.

[A] few decades ago, traditional dairy cows in the western world yielded between 600 and 800 gallons per year, and were productive for at least five to 10 years … Modern herds are expected to average more than 1000 gallons a year [and some even 2000 gallons] … These high-performance cows average only 1.8 lactations, after which they have mastitis and are crippled.

Worse, though, is the mindset behind this use of cloning. For elite animals do not perform well except in cosseted conditions, and are … force-fed on high-grade feed. This requires huge capital – so such animals are intended only for rich countries whose consumers already have more than enough.

Worst of all, the frenetic search for the high-yield animals completely misconstrues the role of livestock. Already we are failing to feed the world’s population. An
estimated one billion out of 6.5 billion people are chronically undernourished while another billion suffer from excess.

The central task is to produce the most nourishment possible from the available landscapes. Food crops produce far more food calories and protein per hectare than livestock, so they should be our priority – cereals, pulses, nuts, tubers, fruit, and vegetables … Cattle and sheep should feed on grass or … trees that grow in places where we cannot easily raise crops … The omnivores like pigs and poultry can feed on surpluses and leftovers.

So farming that is designed to maximise food output produces a lot of plants, with modest amounts of livestock … Plenty of plants, not much meat and maximum variety is precisely what modern nutritionists recommend.

But modern, industrial, high-tech farming has nothing to do with feeding people. It is designed to generate cash.

Dr Alice Roberts

In the latest issue (January 2008) of BBC Focus magazine (science for the intelligent 10-year-old) there’s a mini-interview with one of the few females on TV who really do make my heart beat faster: Dr Alice Roberts, “clinical anatomist, archaeologist, TV presenter and author”, also a very talented artist and a qualified medic. Those of you in the UK who’ve watched either Time Team (Channel 4), Coast (BBC2) or Don’t Die Young (BBC2) will know Alice Roberts as the slightly off-the-wall girlie with the dyed red hair. The interview includes:

What’s the greatest threat to humanity?
Humanity.

Who would you clone?
I wouldn’t. Sexual reproduction is much more exciting.

What would your epitaph say?
Boadicea, Queen of the Iceni. And I’d be buried in a chariot just to fool future archaeologists.

Seriously Zen Mischief!
