| Unfit men working long hours face greater heart risk, study shows Poor physical fitness and working more than 45 hours a week is potentially lethal combination for men aged 40-59Unfit, middle-aged men who work more than 45 hours a week are more than twice as likely to die of heart disease as those who devote less time to their jobs, new research medical research warns today.It identifies the combination of poor physical fitness and working for unusually long hours as a potentially lethal combination for men aged between 40 and 59. However, men who manage to remain physically active into middle age are not at risk, emphasising the health benefits of regular exercise.The findings in the study, in the medical journal Heart, reinforce the health risks being run by men in that age group who are part of Britain's long hours culture. Working excessive hours is thought to damage cardiovascular health by causing someone's heart rate and blood pressure to go up and stay raised for long periods. This happens whether the work itself is physically demanding or not.The heart health and physical fitness levels of some 5,000 Danish men aged 40-59 working for 14 companies was examined for 30 years by a team from the National Research Centre for Denmark's Working Environment.Participants did cycling tests to indicate how fit they are and disclosed how many hours they worked a week. More than two-thirds worked between 41 and 45 hours, but almost one in five clocked up more than 45 hours.Among unfit men, those who were in the latter category were more than twice as likely to die of heart trouble than those who worked for less than 40 hours.Heart health campaigners said that the study underlined the need for middle-aged men to maintain a good level of fitness by taking part in regular physical exercise, despite the pressures on their time.Dr Jane Landon, deputy director of the National Heart Forum, a coalition of 65 health organisations which aims to reduce the damage done by poor heart health, said: "Men in this age group don't need to be doing extreme sports but they do need to be keeping physically fit by, for example, walking or cycling or even doing gardening or DIY, which all contribute to a good level of fitness."Men's risk of developing heart trouble increases as they head into middle age, and is heightened if they put on weight, or have a poor diet or are unfit. The research's conclusion that fit men of the same age and working patterns as those who are unfit proved the protective effects of regular exercise, she said.Cathy Ross, senior cardiac nurse at the British Heart Foundation, said that men should try to be physically active for at least 30 minutes at a time five times a week. "We already know that working long hours can increase blood pressure, a known risk factor for cardiovascular disease."Being physically active helps to control your blood pressure and previous studies have shown that being physically fit can help you cope with the demands of long hours, physically demanding jobs and shift work," she said."This study adds to these findings by demonstrating that men who are physically active as part of their everyday life do not increase their risk of coronary heart disease, irrespective of the number of hours they work."Heart attackHealthMedical researchDenis Campbellguardian.co.uk © Guardian News & Media Limited 2010 | Use of this content is subject to our Terms & Conditions | More Feeds guardian.co.uk |

Lucy Mangan: They can't pull the wool over my eyes. Well, not any more Maybe it's late-onset teenage rebellion, or some kind of early pre-menopausal hormonal adjustment, but a new questioning spirit is stirring within meI am not one of life's natural interrogators. It wasn't the way I was brought up. In fact, looking back, I suspect there were North Korean children who questioned aspects of the regime under which they laboured more closely than I did. It never occurred to me to ask why we couldn't have a drink with soup1, why bumphled cushions couldn't be sat on before 2pm2, why butter was for grown-ups and margarine for children3 and why napkins had always to be folded so the motif was in the bottom left-hand corner4. (Answers, extracted much later in life, below.)However. Things change. Maybe it's late-onset teenage rebellion, maybe it's some kind of early pre-menopausal hormonal adjustment, but of late I have felt a certain new questioning spirit stir within me, a light but distinct scepticism colouring my vision and displacing some of the head-bobbing compliance that has led so many to dismiss me, rightly, as eight-tenths mud turtle.Two recent stories have encouraged me across the threshold into this new world. First, there was the article in the British Medical Journal on how drug companies tried to parlay a claim that 43% of women suffered from "sexual dysfunction" into a lucrative market for Viagra-like pills among the female population. I remember thinking, back in 1999, when the survey in question first appeared, that it seemed more likely – based on anecdotal evidence, common sense and possession of a vagina – that most of those women were, in fact, suffering from "crap shag syndrome". Due to the simpler and happier arrangement of their genitals, men can enjoy themselves by putting said genitals more or less anywhere, as Portnoy's Complaint famously testifies. Julie Burchill once wrote a column opining, in passing, that most men would have sex with mud if there was nothing else on offer. She got a letter from one reader the next day saying that in his adolescence he had done exactly that. Quod erat, possibly on a bit of boggy wasteland near you, demonstrandum.Until they are much older, wiser and/or forcibly instructed otherwise, men approach ladies' bits in the same gung-ho manner. Disappointment is bound to ensue. Such a survey makes you suspect that there are no women involved in science at all. Anyone who has been drinking with her girlfriends and heard the vastly differing sexual experiences that dwell within any one of them, let alone the group, will tell you there's no such thing as a genital attrition rate of 43%. It's all down to chemistry (in the metaphorical rather than pharmaceutical sense) and the dextrous or otherwise wielding of the penoid. I knew that. We all did. But an assertion came from an authoritative-looking group and I thought, "Oh well, there must be something in it." Fool.Ditto the news last week that women being "too posh to push" was a myth. Again, I always thought that one didn't stack up. I know a lot of women. I know quite a lot of doctors. And knowing what I did about them all, I never could visualise a situation in which they'd ask for and agree to (respectively) a caesarean in order to avoid the messy business of natural birth. But again, I presumed that somebody, somewhere knew better. And now, new research reveals, they don't. The vast, vast majority of C-sections are apparently done for medical reasons. That makes a lot more sense.Of course, eventually I shall have to question the new answers, but for now I'm going to concentrate on following up old questions. At last, I'll have a hobby. I'm going to start by asking my mother why the napkins always have to be folded so that the motif lies in the bottom left-hand corner. "Because that's the right way" will no longer suffice. It is a new dawn, and I need answers.1 Because soup's a drink and a meal. 2 To make the bumphling worthwhile. 3 Because of the war. 4 Because that's the right way.Medical researchSexual healthHealthRelationshipsLucy Manganguardian.co.uk © Guardian News & Media Limited 2010 | Use of this content is subject to our Terms & Conditions | More Feeds guardian.co.uk |
In a far corner of Greenland, hope is fading with the language and sea ice Climate change, hunting controls and a new consumerism threaten the way of life of the Polar Eskimos of north-west Greenland. In the second of a series of dispatches, Stephen Pax Leonard reports from a community on the brinkThe sun is slowly disappearing behind the cliffs towards Siorapaluk now it is gone midnight, leaving whale-shaped Herbert Island awash in crimson. It is mid-August and it is my very first evening in the settlement.A couple of tipsy hunters invite me into their wooden, A-framed house and quiz me on who I am and what my purpose is here. Stepping over the narwhal blubber spread out on newspapers on the kitchen floor, I am channelled into the corner settee in the chaotic living room and introduced to the various ancestors whose photographs line the walls, one of whom travelled with Knud Rasmussen to Alaska. I am asked repeatedly if I am a Norwegian from Greenpeace. There is paranoia in the community about Greenpeace and the threat they pose to their hunting culture. One hunter told me that he will be waiting at the shoreline with his guns when they come.In subsequent weeks, I am asked if I am a spy and even if I am one of the 'Blond Eskimos'. The Inughuit are used to the handful of transient and socially invisible Danes that typically work for a few weeks or months at the school or hospital. But, an Oxford-educated Englishman who is present at every social gathering, lives in a small dilapidated, wooden hut on his own and whose aim is explicitly to learn and study their language is an unprecedented oddity whom they cannot easily compartmentalise.In this closed, inward-looking society, the Polar Eskimos are sometimes wary of the outsider and the finger of blame is often pointed at the white man whose market capitalism, individualism and climate change are perceived as catalysts in the demise of their own traditional communal group culture, damaging social cohesion in the process. With the recent EU ban on all seal products, this is even more the case now that the export market for their goods has completely disappeared. The basis for this traditional society has always been the hunting of sea mammals. However, with the self-rule government's restrictions on hunting and the lack of a customer base for their goods, there is almost nobody left who is able to live from hunting alone. Ironically enough, one of the last hunters in this patriarchal society is a woman of Japanese ancestry.The Polar Eskimos have always lived in harmony with nature, taking from the sea and land what they need to survive. But global warming has upset the equilibrium and in a centralising Greenland left the future of the isolated settlements uncertain. The climate in north-west Greenland has become very unpredictable in recent years and hunters no longer know when the sea ice will come or how long it will stay for.Some Greenlanders had high expectations for the climate conference in Copenhagen, but after that disappointment few hold out much hope that the conference in Cancún, which begins tomorrow, will lead to an effective global response to climate change.The transition to a consumer society in some of these settlements has been extremely rapid and has left a plethora of social problems in its wake, including among others the well-documented rampant alcoholism and one of the highest suicide rates in the world.For centuries, the proud Inughuit (who the likes of Peary, Cook and Rasmussen were very dependent on) have overcome the problems of the severe cold, famine and isolation, but some have now fallen victim to apathy and Danish welfare dependence which has partially replaced an ancient system of production.The trappings of welfare dependence and modern western society have inevitably taken their toll on the indigenous culture of story-telling, too. The loss of their rich oral heritage seems particularly sudden and jarring, given that it has been replaced in part by a diet of violent, expletive-packed American films and apparently addictive bingo. For the most part, the Inughuit no longer sit around reciting stories and myths to one another, but are instead glued to unsubtitled Danish television (Greenlandic words are too long to subtitle). Thus, few people understand the programmes, albeit the very popular Danish cartoons require ostensibly little translation.This sudden shift in cultural norms makes the performance of the last remaining story-tellers all the more extraordinary. I have been documenting episodes of the life story of an 88-year-old man. This former hunter has a prodigious memory describing in great detail events that happened over 60 years ago.Vast knowledge of the land, sea and ice are all stored orally; the Inuktun language has never been systematically written down. A 76-year-old woman sits in my hut, telling me a story about the semi-nomadic life they lived when she was growing up. I present her with one of the few texts ever written down in Inuktun and she looks nonplussed and confused: towards the end of her life, she has just seen her own language written down for the first time.There is no doubt that the language itself can operate as something of a social trap. The Inughuit are not sure how to write Inuktun because it is not a written language, but some are not confident writing Standard West Greenlandic either as, orthographically, it is alien and does not represent spoken language.Without being able to write Greenlandic, young people will have few opportunities elsewhere in Greenland. They are proud of their own language, Inuktun, as it underpins their distinct culture, but at the same time it offers young people no opportunities, and in fact deprives them of some. If they leave the community, they will have to drop their language and switch to the West Greenlandic language. If they do that, then they are to an extent severing their cultural ties with the homestead. As speakers of the Standard language, they may not be seen as real Polar Eskimos.The Inuktun word for "winter" is "ukiuq" (the same word is used for "year" – presumably the two used to be more or less synonymous), and here, in the bosom of the Arctic, winter has now arrived. The cliffs to the east with their folds forming the shape of a granite accordion have previously been radiating hues of red and purple in the late evening summer sun, but are now uncompromisingly white. Now, the landscape and the sky form a patina of subtle blends of grey and white. Tilted-eyed huskies bay the rising gibbous, candles flicker nervously behind frosted window pains and wooden sledges jounce over the snow-covered scree tracks.Two weeks ago the sea was a gelatinous, viscous grey soup, but the snow-covered sea ice now stretches for a few kilometres away from the settlement, with the open sea visible in the distance. Cathedrals of ice sit like protruding teeth from off-white gums – their passage through the Murchison Sound halted for several months. Two forgotten motorboats are frozen in place, the sea ice having closed in around them.The temperature has plummeted and the battle is now on to heat the non-insulated wooden hut where I live. It is below freezing in the bathroom and I have on a number of occasions slept in sub-zero temperatures due to problems with the oil heater, losing already one computer to the cold. Each day is now colder than the last, and we are almost cloaked in 24 hour darkness too...Stephen Pax Leonard is an anthropological linguist at the Scott Polar Research Institute and research fellow at Trinity Hall, Cambridge. He is living with the Inughuit people for 12 months. His research is funded by the British Academy and the World Oral Literature Project in Cambridge.
