Conundrum: Aviator’s headscratcher…

Conundrum

‘You’re really going to fly around the Earth from North to South?’ said the young man to the aviator. ‘I’ll bet you’ll need your thermal underwear when you pass over the Poles!’

‘Actually,’ the intrepid airman replied, ‘the Poles are the least of my worries: I shall have to pass twice over a much colder area than that.’

What could it be?

Answer: The air above the Equator is much colder than the air over the Poles (because at that point there is a greater height of air and therefore the temperature can fall lower).

Health risk for women in their 30s who do not exercise…

HEART RISK

A major study has found that a lack of exercise puts younger women at far greater risk of heart attacks than smoking or being obese.

Researchers found inactive women in their 30s are almost 50 per cent more likely to develop heart disease in their lifetime than those who are fit.

The team has now called on governments to launch public health campaigns on the importance of exercise, arguing it would have a far greater impact on reducing heart disease deaths than drives to discourage smoking or promote healthy eating.

The scientists looked at the records of 32,541 women aged 22 to 90, including details about lifestyle and whether they had heart disease. Armed with this data, they used a mathematical formula to work out their risk of heart disease during their lifetime based on whether they were inactive, were smokers, had hypertension (high blood pressure) or were obese.

A lack of exercise was found to pose the greatest risk to women across all age groups.

Those in their early 30s who were classed as inactive were nearly 50 per cent more likely to suffer from the condition in their lifetime than active women.

The risk decreased slightly with age. Inactive women in their late 40s were 38 per cent more at risk, falling to 28 per cent in the late 50s.

By comparison, the risk was 40 per cent for women smokers in their 30s and 30 per cent for the obese. Although obesity and being unfit are closely linked, the researchers from the University of Queensland pointed out that many slim women are inactive.

The latest UK figures show a quarter of women are classified as inactive, while just over half do the recommended two and a half hours of physical activity a week.

Heart disease, which includes heart attacks and strokes, is by far the biggest killer in Britain, claiming 82,000 lives a year.

Experts have previously claimed that exercising can halve the risk of getting the condition because it lowers the blood pressure, reduces cholesterol which blocks arteries, and improves circulation.

Professor Wendy Brown, one of the team’s lead researchers, described inactivity as the ‘Cinderella risk factor’ for heart disease. She said: ‘Our data suggests that national programmes for the promotion and maintenance of physical activity across the adult lifespan, but especially in young adulthood, deserve to be a much higher public health priority for women than they are now.’

The study’s findings, first published in the British Journal of Sports Medicine, concluded: ‘Continuing efforts to reduce smoking rates in young adult women are warranted… however, from about age 30, the population attributable risk for inactivity outweighs that of the other leading risk factors, including high Body Mass Index, which is currently receiving much more attention.’

A spokesperson for the British Heart Foundation, said: ‘We already know physical inactivity is a major risk factor for heart disease. Interestingly, this study shows its dominant influence on heart disease amongst women, and suggests a greater need to promote regular physical activity… It is important to remember that heart disease is linked to other factors such as smoking, obesity, high blood pressure and high cholesterol.’

Preventing dismemberment of Ukraine requires conciliatory compromise…

UKRAINE

In the aftermath of the Donetsk referendum on independence for the new ‘People’s Republic’, Roman Lyagin, the region’s self-styled electoral commissioner, has proclaimed a charade of an election result. The fact that the total of the yes, no and spoilt votes exceeded 100 per cent, Western observers – including the British Foreign Secretary William Hague – rightly concluded that this contest was ‘illegitimate’ and had ‘zero credibility’.

Despite the surreal nature of the plebiscite, the outcome is nothing other than deadly serious. The most populous regions of Ukraine, with 4.5 million people and the industrial powerhouse of the economy, now stands on the brink of merging with Russia. We should be under no illusion: the shadowy circle of kleptocratic pro-Kremlin leaders who organised this poll, with the resulting 89 per cent ‘yes’ vote, is leading the eastern regions of Donetsk and Luhansk along a road that seems certain to end in union with Russia.

Ukraine’s new post-revolutionary government has no answer to the challenge. In what was described as a military offensive by the Ukrainian army prior to Sunday’s vote in restoring control over Donetsk, that strategy can only be deemed a fiasco upon reflection. The city of Mariupol, with its half-a-million residents, has effectively been conceded to the pro-Russian movement.

A chink of light may, however, provide a way out of the crisis. One of the referendum’s absurdities was a vague and indiscreet question that asked voters to assent to ‘self-rule’, clearly something which should have been clarified as to meaning. If Kiev were now to open proper talks and dialogue with the pro-Russian movement and make a generous and specific offer of regional autonomy, that might allow both sides to step back from the brink. Those hardliners in Kiev will no-doubt have difficulty in negotiating with a motley collection of Russian allies, particularly as Moscow is once again ramping up the threats to turn off Ukraine’s gas supplies, but the alternative will only exasperate an already tense and bitterly volatile situation.

It seems certain now that, given the events in Ukraine over the past few months, unless a bold and conciliatory move is made by Kiev, the dismemberment of Ukraine looks inevitable.
