British women walking taller

Scientists say British women have grown taller faster than most of the rest of the world.

British women now average 5′ 5″ (164.4 cm) compared to 5′ (153.4 cm) at the start of the century.

This pushes them up the world league table of the tallest from 57th place in 1914 to 38th place today.

British men have grown to 5′ 10″ (178 cm), up 10.6 cm, and have moved up from 36th to 31st place.

Who are the tallest?

Latvian women are the tallest and  average 5′ 7″ (170 cm)

Dutch men are the tallest at 6′ (183 cm)

Who are the shortest?

Men from East Timor and the Yemen at 5′ 3″ (160 cm), Laos (161 cm), Madagascar and Malawi (both 5′ 4″ or 162 cm).

Women from Guatemala at 4′ 11″ (149 cm), the Philippines  (150 cm), and Bangladesh, Nepal and East Timor (all 151 cm).

The researchers compared data from people who were 18 in 914 with those of the same age in 2014. The difference is partly genetic and partly due to nutrition, sanitation, and health. Particularly important is the mother’s health and nutrition during pregnancy.

Height is a mirror to our social environment” said Professor Majid Ezzati from the School of Public Health at Imperial College.

The biggest increases have been in rapidly developing countries such as Japan and South Korea where women are now 8″ (20 cm) taller than before WW11. Iranian men have grown by the same amount.

Americans have grown by 5cm over the review period but have dropped down the league tables from 3rd for men and 4th for women in 1914 to 37th and 42nd place respectively. This was probably connected to their obesity problem – lots of calories but not good nutrition – said Professor Ezzati.

In sub-Saharan Africa people are actually getting smaller.

Tall people tend to have a longer life expectancy, with a reduced risk of heart disease. On the other hand, there is some evidence that they are at greater risk of certain cancers, such as colorectal, postmenopausal breast and ovarian cancers.

One hypothesis is that growth factors may promote mutated cells,” said another Imperial co-author, Elio Riboli.

I’m always a bit bemused by stories like this about average height because I come from a tall family and am used to being around tall people. 6′ (183 cm) doesn’t seem tall to me yet it’s taller than the average British male.

And being tall does have some advantages at work.

Domestic abuse law not being enforced by police

It’s two years since the new offence of coercive and controlling behaviour (see my post on this here) came into force yet only 532 charges have been brought in England even though more than 4,000 offences were recorded by the police in one year.

The offence carries a maximum sentence of 5 years.

Six police forces have brought 5 charges or less and only eight of the 43 forces in England and Wales have taken up an accredited training programme dealing with the offence.

Elfyn Llwyd, whose private members’ bill led to the introduction of the offence said it was very frustrating that training had been so low. “The poor take-up of training among the Welsh and English police is reflected in the low number of prosecutions. The government must ensure that training is made mandatory and funded centrally“.

It’s just not good enough. When police forces are spending money demonstrating how PC they are by painting their cars and finger nails it suggests that they haven’t got their priorities right in protecting victims of what Theresa May, then Home Secretary, said could be “tantamount to torture”.

Essex police were also criticised for their campaign offering support to over-55 year old victims of domestic abuse who decided to stay with their partners.

It included a fictional case study which said “She knew the abuse in her relationship was wrong but also knew she wouldn’t leave. With help and support from specialist organisations and agencies she and her husband stayed together, but safely”.

Refuge, the domestic violence charity, were less than impressed saying it was the police’s job to arrest abuse perpetrators and that it seemed they were failing victims. Every week two women were killed by their partners or former partners.

Essex police acknowledged it had used “clumsy language“.


Self-service in supermarkets means help yourself – to the tune of £3 billion a year

Or just steal it?

Just over three years since I posted about self-scanning, self-service tills, and the opportunities for theft.

The figures just published show that shoplifters are stealing £3billion a year using self-service!

One in four people actually admit to stealing almost £25-worth each month so you wonder about the actual numbers. The level of stealing has doubled in the last four years equivalent to £5 per person in Britain per month usually vegetables, toiletries and dairy products. Northerners  and Scots steal almost twice as much as Southerners

Some of the losses are attributed to faulty equipment which doesn’t scan or register items properly but 40% of the shoplifters said they knew they could get away with it.

With 50,000 machines – 12,000 in Tesco alone – the potential for theft is enormous. And who pays for it? Well honest customers do as prices are adjusted to allow for theft.

The company which carried out the survey said “ Supermarkets need to increase the number of staff who monitor the self-scan check-outs even though the point of these is to reduce the need for staff“.

Call me a Luddite but I prefer to actually pay at a till with some human interaction. All these cost-saving attempts at raising  productivity have loopholes that people will exploit.


The world is becoming more short-sighted

A couple of years ago I posted this elsewhere when experts were blaming too much time spent on near electronic devices, smartphones, tablets, Kindle et. With the increase in the use of mobile gadgets and smartphones since then the risk must still be there, if not greater.

It’s been suspected for a while that lack of outdoor activity – for various reasons including safety fears – where you are exposed to UV light and can focus on distant objects more easily, and over-indulgence in screen time, has led to an increase in the number of myopic i.e. short-sighted, children. I also posted on research from Cambridge University about this over six years ago.

More recently scientists, at the Brien Holden Vision Institute in Australia, were predicting that half the world could be short-sighted by 2050 with 1 in 10 people suffering sever myopia.

The increase is particularly acute in Asia. 90% of teenagers and young people in China are short-sighted and in Seoul 96.5% of 19-year old men are too. In Europe and the West about half of young adults have the condition.

The scientists, reporting in the journal Opthalmology,  said “Among environmental factors, so-called high pressure educational systems, especially at a very young age in countries such as Singapore, Korea, Taiwan, and China, may be a causative lifestyle change, as may the excessive use of near electronic devices

If true the message is clear. Get off your backside, ditch the gadgets and get outside to enjoy the scenery.


If you want to be happier – ditch Facebook!

Just a reminder

ulearn2bu

stick_figure_liking_it_500_wht_9170Research from The Happiness Research Institute in Copenhagen in Denmark (one of the happiest countries in the world) has found that giving up your Facebook account boosts happiness and reduces anger and loneliness.

Life satisfaction rose significantly in the space of a week when participants were unable to read the updates of their friends. The institute was surprised by the changes in such a short time and wants to raise awareness on the influence of social media on feelings of fulfilment.

Facebook and other social media sites are “a constant flow of edited lives which distort our view of reality” it said in its report The Facebook Experiment.

They recruited over a thousand people in Denmark and asked half of them to avoid Facebook for a week. Participants were asked to rate their life satisfaction on a scale of 1 to 10 before and after the experiment.
