Children, a blessing

Never underestimate the potential you have to touch a child's life! 

Yesterday I got a letter from a lovely young lady who is nearly 12 - I last saw her when she was 4. But as her Mom is one of my very best friends, we have stayed in touch over the years. I was very touched that she was so attached to me still after so many years. I have always loved this girl and her family and prayed for them, but never thought I was making any impact on her life. It totally blew me away that God could use the time we spent together all those years ago when she was so little, to instill in her how precious she is to me - and that she would remember this 8 years later!

What an awesome responsibility and joyfully rewarding love we have to give! What enormous potential we have as adults to touch children with God's love, to pray for them and be blessed by them as we enjoy them. Not only our own children, but our friends children and our children's friends and children in the community too. I hope that all the many children who have been a part of my life know that I still love them and pray for them! (even those who think I would scorn them for not walking with God as they have reached adulthood.)

Never hesitate to put all your love and effort into ever child God brings into your life. Truly it is worth every effort a millions times over, for the blessing those children will be to you.

Are we becoming internet Zombies?


Here is an interesting article that Douglas sent to me...


"How the internet makes us stupid
September 10, 2010
Nicholas Carr ... inspired to write the book after he realised that he was losing his own capacity for concentration and contemplation.
The stimulation of the digital age is changing the make-up of our brains, with potentially disastrous results, writes Nicholas Carr.
ALTHOUGH the worldwide web has been around for just 20 years, it is hard to imagine life without it. It has given us instant access to vast amounts of information, and we're able to stay in touch with friends and colleagues more or less continuously.
But our dependence on the internet has a dark side. A growing body of scientific evidence suggests that the net, with its constant distractions and interruptions, is turning us into scattered and superficial thinkers.
I've been studying this research for the past three years, in the course of writing my new book The Shallows: How the Internet Is Changing the Way We Think, Read and Remember. But my interest in the subject is not just academic. It's personal. I was inspired to write the book after I realised that I was losing my own capacity for concentration and contemplation. Even when I was away from my computer, my mind seemed hungry for constant stimulation, for quick hits of information. I felt perpetually distracted.
Could my loss of focus be a result of all the time I've spent online? In search of an answer to that question, I began to dig into the many psychological, behavioural, and neurological studies that examine how the tools we use to think with - our information technologies - shape our habits of mind.
The picture that emerges is troubling, at least to anyone who values the subtlety, rather than just the speed, of human thought. People who read text studded with links, the studies show, comprehend less than those who read words printed on pages. People who watch busy multimedia presentations remember less than those who take in information in a more sedate and focused manner. People who are continually distracted by emails, updates and other messages understand less than those who are able to concentrate. And people who juggle many tasks are often less creative and less productive than those who do one thing at a time.
The common thread in these disabilities is the division of attention. The richness of our thoughts, our memories and even our personalities hinges on our ability to focus the mind and sustain concentration. Only when we pay close attention to a new piece of information are we able to associate it ''meaningfully and systematically with knowledge already well established in memory'', writes the Nobel prize-winning neuroscientist Eric Kandel. Such associations are essential to mastering complex concepts and thinking critically.
When we're constantly distracted and interrupted, as we tend to be when looking at the screens of our computers and mobile phones, our brains can't forge the strong and expansive neural connections that give distinctiveness and depth to our thinking. Our thoughts become disjointed, our memories weak. The Roman philosopher Seneca may have put it best 2000 years ago: ''To be everywhere is to be nowhere.''
In an article in Science last year, Patricia Greenfield, a developmental psychologist who runs UCLA's Children's Digital Media Centre, reviewed dozens of studies on how different media technologies influence our cognitive abilities. Some of the studies indicated that certain computer tasks, such as playing video games, increase the speed at which people can shift their focus among icons and other images on screens. Other studies, however, found that such rapid shifts in focus, even if performed adeptly, result in less rigorous and ''more automatic'' thinking.
In one experiment at an American university, half a class of students was allowed to use internet-connected laptops during a lecture, while the other had to keep their computers shut. Those who browsed the web performed much worse on a subsequent test of how well they retained the lecture's content. Earlier experiments revealed that as the number of links in an online document goes up, reading comprehension falls, and as more types of information are placed on a screen, we remember less of what we see.
Greenfield concluded that ''every medium develops some cognitive skills at the expense of others''. Our growing use of screen-based media, she said, has strengthened visual-spatial intelligence, which can strengthen the ability to do jobs that involve keeping track of lots of rapidly changing signals, such as piloting a plane or monitoring a patient during surgery. But that has been accompanied by ''new weaknesses in higher-order cognitive processes'', including ''abstract vocabulary, mindfulness, reflection, inductive problem solving, critical thinking, and imagination''. We're becoming, in a word, shallower.
Studies of our behaviour online support this conclusion. German researchers found that web browsers usually spend less than 10 seconds looking at a page. Even people doing academic research online tend to ''bounce'' rapidly between different documents, rarely reading more than a page or two, according to a University College London study. Such mental juggling takes a big toll. In a recent experiment at Stanford University, researchers gave various cognitive tests to 49 people who do a lot of media multitasking and 52 people who multitask much less frequently. The heavy multitaskers performed poorly on all the tests. They were more easily distracted, had less control over their attention, and were much less able to distinguish important information from trivia.
The researchers were surprised by the results. They expected the intensive multitaskers to have gained some mental advantages. But that wasn't the case. In fact, the multitaskers weren't even good at multitasking. ''Everything distracts them,'' said Clifford Nass, one of the researchers.
It would be one thing if the ill-effects went away as soon as we turned off our computers and mobiles. But they don't. The cellular structure of the human brain, scientists have discovered, adapts readily to the tools we use to find, store and share information. By changing our habits of mind, each new technology strengthens certain neural pathways and weakens others. The alterations shape the way we think even when we're not using the technology.
The pioneering neuroscientist Michael Merzenich believes our brains are being ''massively remodelled'' by our ever-intensifying use of the web and related media.
In the 1970s and 1980s, Merzenich, now a professor emeritus at the University of California in San Francisco, conducted a famous series of experiments that revealed how extensively and quickly neural circuits change in response to experience. In a conversation late last year, he said that he was profoundly worried about the cognitive consequences of the constant distractions and interruptions the internet bombards us with. The long-term effect on the quality of our intellectual lives, he said, could be ''deadly''.
Not all distractions are bad. As most of us know, if we concentrate too intensively on a tough problem, we can get stuck in a mental rut. But if we let the problem sit unattended for a time, we often return to it with a fresh perspective and a burst of creativity.
Research by the Dutch psychologist Ap Dijksterhuis indicates that such breaks in our attention give our unconscious mind time to grapple with a problem, bringing to bear information and cognitive processes unavailable to conscious deliberation. We usually make better decisions, his experiments reveal, if we shift our attention away from a mental challenge for a time.
But Dijksterhuis's work also shows that our unconscious thought processes don't engage with a problem until we've clearly and consciously defined what the problem is. If we don't have a particular goal in mind, he writes, ''unconscious thought does not occur''.
The constant distractedness that the net encourages - the state of being, to borrow a phrase from T. S. Eliot, ''distracted from distraction by distraction'' - is very different from the kind of temporary, purposeful diversion of our mind that refreshes our thinking. The cacophony of stimuli short-circuits both conscious and unconscious thought, preventing our minds from thinking either deeply or creatively. Our brains turn into simple signal-processing units, shepherding information into consciousness and then back out again.
What we seem to be sacrificing in our surfing and searching is our capacity to engage in the quieter, attentive modes of thought that underpin contemplation, reflection and introspection. The web never encourages us to slow down. It keeps us in a state of perpetual mental locomotion.
The rise of social networks such as Facebook and Twitter, which pump out streams of brief messages, has only exacerbated the problem.
THERE'S nothing wrong with absorbing information quickly and in bits and pieces. We've always skimmed newspapers more than we've read them, and we routinely run our eyes over books and magazines to get the gist of a piece of writing and decide whether it warrants more thorough reading.
The ability to scan and browse is as important as the ability to read deeply and think attentively.
What's disturbing is that skimming is becoming our dominant mode of thought.
Once a means to an end, a way to identify information for further study, it's becoming an end in itself - our preferred method of both learning and analysis.
Dazzled by the net's treasures, we have been blind to the damage we may be doing to our intellectual lives and even our culture."

Vitamin D Deficiency - could you have it?

It has been called the silent epidemic here in Australia, and was first discovered when Muslim women new to Australia became vitamin D deficient because they no longer had private court yards where they could remove their coverings. It then followed that sunblock/sunscreen was doing the same preventing of sun getting to skin.

In recent weeks we have discovered that our family has a Vitamin D deficiency problem and probably for a lot longer than we have realised. Testing for it came about because one child was very tired and run down after glandular fever, ongoing flue etc and I had taken him back for a third opinion over a period of 18 months. His symptom - just tired! We stumbled across a GP who has an interest in Vitamin D deficiency and figured symptoms and testing for it among a ream of other tests. As it turns out he is not the least deficient, and some of the kids are radically deficient! The consequences can be quite profound and scary. And I wonder if we have been misdiagnosing a number of things over recent years. Take a look at these web sites. (I see no mention of mental agility, but if it effects mood and tiredness, no doubt it could effect mental alertness and ability to learn too!)

Why are we so deficient? Well, all good parents "slip, slop slap", don't they? In our case too much of a good thing was not so good.

So get out with your kids minus the "slip slop, slap" and soak up some sun in the early mornings and late afternoons before the sun is dangerous.

And don't hesitate to get ask your GP to test for Vit D deficiency if your child has any possible symptoms. The cure is fairly easy... to start off heaps of a Vit D supplements, with follow up tests to monitor and of course sun minus the "slip, slop, slap"!
Weird that in sunny Queensland we can suffer because we do not let the sun access our skin?

  So soak up the sun! And forget about the cancer scares during safe times. Check out this web site to figure out safe times for sun exposure in Australia -

New Hymns

We have been learning two new hymns recently. They are both found in Stuart Townends newer Hymn Maker CD. Neither are easy to learn but both are worth the effort to learn them, as the words and music are beautiful.

(1) There is a Hope:



For lyrics and music see http://www.musicnotes.com/sheetmusic/mtdVPE.asp?ppn=MN0067540

For video see http://www.youtube.com/watch?v=qyMWBx6vvJo


(2) The second one is a puritan prayer which has been put to music: "Blessed Spirit of the King". You just have to read these words of great depth! Who cannot be moved by such depth, and who can not be stuck by our frivolity in comparison to this puritan writer.
