Something else from our garden. This is Rosa gallica, the Apothecary’s Rose of ancient times. It grows madly in all directions wherever we plant it; apparently it likes clay soil, which being in London is what we have.

This week’s self-portrait: 52 Weeks 16/52 (2008 week 24).
Yes it’s horrible, and I’m seriously over-weight … but not as much as I was; I’ve lost 28kg (almost 4.5 stone) since October. That’s not fast, but it is fast enough considering I am diabetic and while controlling calories also have to be careful to keep my blood glucose stable. Actually losing the weight has helped a lot with my blood sugar levels and my blood pressure, so although it isn’t easy it is worth doing; I do feel lots better for it. But I really need to get rid of at least that much again if I possibly can.
Oh and yes, the tile effect is a shameless abuse of Photoshop – just to save the worst of the blushes of the innocent. Being nude, anywhere, anytime, bothers me not at all ‘cos I was brought up as a nudist! But I know it does bother others, so out of respect for them there is nothing here that you wouldn’t see in a swimming pool.
Book Meme
OK just for something a bit different, here’s a book meme I came across the other day …
One book that changed your life:
Anthony Powell; A Dance to the Music of Time
One book that you have read more than once:
Martin Gardner; The Annotated Alice
One book that you would want on a desert island:
Latham & Matthews; Diaries of Samuel Pepys. That’s apart from Dance!

One book you wish you’d written:
Almost anything really; I just wish I had the skill and imagination to write a book.
One book you wish had never been written:
Not sure I think any book shouldn’t exist (that’s a variant of free speech), but if I really had to choose I’d pick two books: the Bible and the Koran; they’ve done more damage in the world than possibly all other books put together.
One book you’re reading:
Jennifer Ouellette; Black Bodies and Quantum Cats: Tales of Pure Genius and Mad Science
One book you’re going to read:
John Aubrey; Brief Lives

Kew Gardens
London Zoo
We’re on holiday, but not away, this week and next. So we are trying to have a few days out, weather permitting which it didn’t on Monday and Tuesday.
Yesterday we went to London Zoo. I’ve not been to the Zoo since I was a teenager (the Snowdon Aviary wasn’t long open) – so over 40 years ago! And Noreen has never been despite having lived in London for over 30 years and done most of the tourist things.
What a disappointment. I’m glad I went, but to be honest I probably won’t bother again. Although we didn’t look at everything, we did see a large proportion. Now I know we’re all used to seeing animals in action in 5 second “vision bites” on TV, and that in reality most animals spend a lot of their day doing very little. But even allowing for that I found the “exhibits” dull. Why?
Many of the indoor enclosures looked drab, dull, unexciting and almost uncared for. Which I know does an injustice to the keepers, as they care greatly about giving their animals the best possible environment. The indoor spaces were frankly rather tatty and in need of a good coat of paint; not really surprising when you look at the number of pairs of feet walking round.
I suppose the thing which struck me most was the lack of variety. Sure there are birds and reptiles; fish; mammals of all types and sizes; insects and bugs. But I felt there was not enough variety of each, although of course space is very limited and one has to provide enough room for the number of visitors as well as the animals and staff as well as having some exhibit spaces empty and being refurbished. Nevertheless I felt that many of the animals are still kept in inadequately sized accommodation – specifically I don’t feel it ethical to keep an owl in an aviary where it doesn’t get a good long flightpath (20 x 30 x 8 feet high really doesn’t feel large enough!).
And the limitations of space, and even money, don’t excuse labels which were uninformative to anyone except a 10 year-old doing their school project. The science content of the labels for people like me was non-existent. OK, I set a high standard because I’m a scientist, but there should be something there to capture me too; I also need to be made to say “Heavens, I never knew that!” And by doing this you stretch other visitors and make them think. It’s a hard task; yes a lot of the labelling has to enthuse the school kids and the less well educated; that doesn’t mean that there shouldn’t be some (not all) information at a higher level.
And heavens the number of school kids! The whole place was crawling with school parties – all ages from 5 to 15 (or more). It’s a bit much when the noise of the kids drowns out the local starlings and the London traffic! Don’t get me wrong; it’s great that the kids are there and hopefully showing some interest (especially in a pair of turtles having it off! – the whole group of 8 year-olds had their mobile phones out taking photos!). Yes, they are the future and we need to catch ’em young and get them enthused about science in all forms. But it I would have felt more sanguine about it if I thought they were learning something and not just wandering round ticking boxes on the project sheet or meandering aimlessly. Most of the teachers didn’t seem too interested either, except to try to rein the kids in a bit; they weren’t doing any much teaching.
As a fishkeeper the area I really wanted to see was the Aquarium. Frankly I felt that this was a disgrace. Half the exhibit space appeared to be boarded off, with no word of explanation. Was it because it is being rebuilt; refurbished; closed because unrepairable (the building is old now); there isn’t the money to run it? Why? Nothing; just blank dark blue hoarding in a space so dark one could hardly see where one was walking. The tanks which were in use were to my mind unexciting and all too small. Yes there was a variety of freshwater and salt-water fish, tropical and temperate; but with a few exceptions (like large Tambaqui, fragile seahorses and quantities of anemones and corals) nothing a good amateur aquarist couldn’t keep at least as well. And almost nothing about crustaceans, shellfish, seaweed and no really good biotype displays.
So what was good? The staff were all helpful. The grounds are immaculately kept. Some exhibits were good. The penguins and meercats were an especial and unexpected delight. As was the large tiger dozing against the wall of his enclosure, literally just a foot the other side of the Plexiglas from us. Likewise the two very asleep, and very beautiful, Servals looking like oversized spotted domestic cats. The Lubetkin Penguin Pool is still there (it is Grade I listed) and refurbished but not in use (sad; I hope a use can be found for it other than for wire sculptures of insects). Noreen enjoyed the rainforest displays. The café is decent, even if not cheap (but then where is?). And the loos were spotless despite the hoards of kids.
I’m sure there is more that’s good – we didn’t see everything – but that doesn’t feel like a good return on the almost £20 admission price. Sad, really; very sad.
And there are a few of my photos of the animals over on Flickr; hopefully more to come later.
Summer in England
How do you know it’s summer in England? No not because the sun is shining. Because it’s raining! It really is almost that predictable.
We’re on holiday for a couple of weeks at present; a badly needed break. Unfortunately we failed in our attempts to go away because we were unable to find anyone to feed the cats (none of our 3 cat feeders is available, nor is our local cattery; they’re all on holiday too!). So we’re staying home and trying to go out for days. But it’s raining! – nice steady summer rain which looks set for the day.
The two top things we want to do are go to London Zoo (I’ve not been since I was a child) and go to Kew Gardens. Both are largely outdoors. Which ain’t too much fun when it’s peeing down with rain. There are few things more miserable, in my mind, than being out for the day in the rain.
At least the rest of the week looks good. Meanwhile we’re at home doing a few odd jobs around the place and not much else.
Update, 1735 hrs. And it is still raining; don’t think it’s stopped all day! We’ve spent the day pottering about and clearing out all the old toot from our wardrobes.
Sex Education
There’s an interesting article in last week’s issue of New Scientist in which Hazel Muir questions why it is that governments (indeed whole societies) ignore scientific evidence when making policy. Of particular interest to me was the comments on federal funding of sex education programmes for teenagers. As the full article isn’t available to non-subscribers, I give you a couple of telling paragraphs …
Among other requirements, the [abstinence-only sex education] programmes must teach “that sexual activity outside of the context of marriage is likely to have harmful psychological and physical effects”. A 2004 report commissioned by a Democratic congressman concluded that four-fifths of the curricula contained false or misleading information, such as hugely exaggerating the risk of pregnancy or HIV transmission when condoms are used.
“The origin of this programme was not in science or research by any means, but in an ultra-conservative, ultra-religious ideology,” says James Wagoner, president of Advocates for Youth, a non-profit organisation in Washington DC that champions informed decision-making about sexual behaviour. “You could almost see the abstinence-only movement as the sexual health equivalent of creationism.”
Several studies, including a Congress-funded randomised controlled trial involving more than 2000 teenagers, showed the abstinence-only programmes were no more likely than conventional sex education to prevent or delay teenagers having sex, or reduce their number of sexual partners. Yet Congress continues to fund the programmes. Peer-reviewed studies of more than a dozen well-considered programmes for scientific sex education show these programmes can both make teenagers delay having sex and increase contraceptive use if they do have sex: “But how many of these would be eligible for federal funding? Zero,” Wagoner says.
Now why does the US have the highest rate of unplanned teenage pregnancy in the western world? Makes you think, doesn’t it!?
Something for the Weekend
Being an unrepentant red-blooded male, an inveterate people-watcher and a photographer I cannot resist a deliciously pretty girl. So here are a couple I spotted earlier in the week on my way back from a business trip to Glasgow.
More photos of all sorts on my flickr photostream.
Agriculture Policy
I’ve posted before about the need for a paradigm shift in agriculture policy (see here and here). There is an article by Jeffrey D Sachs in the June 2008 issue of Scientific American which picks up on this theme – although to my mind he doesn’t go far enough. As the article isn’t (yet) online, here is an edited version:
Surging Food Prices and Global Stability
Misguided policies favor biofuels and animal feed over grain for hungry peopleThe recent surge in world food prices is already creating havoc in poor countries, and worse is to come. Food riots are spreading across Africa, although many have gone unreported in the international press. Moreover, the surge in wheat, maize and rice prices … has not yet fully percolated into the shops and … the budgets of relief organizations … In early 2006 a metric ton of wheat cost around $375 on the commodity exchanges. In March 2008 it stood at more than $900 …
Several factors are at play in the skyrocketing prices … World incomes have been growing at around 5% annually in recent years … leading to an increased global demand for food … The rising demand for meat exacerbates the pressures on grain and oilseed prices because several kilograms of animal feed are required to produce each kilogram of meat. The grain supply has also been disrupted by climate shocks …
An even bigger blow has been the US decision to subsidize the conversion of maize into ethanol to blend with gasoline. This wrongheaded policy … gives a 51% tax credit for each gallon of ethanol blended into gasoline. The Energy Policy Act of 2005 mandates a minimum of 7.5 billion gallons of domestic renewable-fuel production … overwhelmingly … corn-based ethanol, by 2012. Consequently, up to a third of the US’s Midwestern maize crop this year will be converted to ethanol, causing a cascade of price increases … (Worse still, use of ethanol instead of gasoline does little to reduce net carbon emissions once the energy-intensive full cycle of ethanol production is taken into account.)
The food price increases are pummelling poor food-importing regions … Several countries … have cut off their rice exports in response to high prices at home … Even small changes in food prices can push the poor into hunger and destitution … some of the greatest famines in history were caused not by massive declines in grain production but rather by losses in the purchasing power of the poor.
… measures should be taken in response to the food price crisis. First, the world should … fund a massive increase in Africa’s food production. The needed technologies are available – high-yield seeds, fertilizer, small-scale irrigation – but the financing is not. The new African green revolution would initially subsidize peasant farmers’ access to better technologies [… and …] help farm communities establish long-term microfinance institutions …
Second, the US should end its misguided corn-to-ethanol subsidies … Third, the world should support longer-term research into higher agricultural production. Shockingly, the Bush administration is proposing to sharply cut the US funding for tropical agriculture studies … just when that work is most urgently needed …
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.
