What I've noticed, in terms of intellectual development is the broad damage done to it by incestuious behaviour of family groups: By the promotion of homosexuality as a desirable alternative to normal and natural interactions in society between its members.
And of course, politicians and their scamming, and of other phanomina such as 18c of the racial discrimination act. Re; above article.

There is actually less pollution in London than a hundred a fifty years ago. What I have observed towards promotion of madness, is society and its fixation on the "stupid".
People have the need to actually get a life for themselves that promotes their own wellbeing. That may be living under a gum tree in a tent for some.

As for the dangers of living on busy roads. Most of that particular real estate was sold to new immigrants as cheap and affordable. (I note the authors name).
There are a potential of 1.2 billion Chinamen who are more than willing to exchange a 30th floor apartment in Beiling for a three million dollar apartment overlooking the Cahill expressway in the Sydney CBD. I'd suggest the last concern on their mind is dementia.

The point? People living on busy polluted roads is not about to change

Excellent well researched article, only the brain dead could ignore!

Even so, some regional planners want to stack and pack people into smaller more polluted places? Why? Because for some folk, their only God is the mighty dollar?

So what if demented folk live longer and in high care ultra expensive nursing homes, force fed statins that further diminish their cognitive abilities, always providing it remains big pharma's most lucrative profit earner!?

As long as planners and politicians see people, merely as numbers serving a flawed economic paradigm as its slaves? None of this will, as D.D., has noticed, change?

However, if sanity ever prevails, the inmates returned to their dorms/sedated and folks with still normal functioning cerebral cortex's put back in charge of the asylum?

Maybe some rationality will return and the economy made to serve us, instead of the current imposed (look mum, tinned people) example? And ridiculous in a land as large as Australia!

When that day finally dawns, we will, find a way, to roll out rapid rail and fibre to the home High speed N.B.N! And decarb the economy!

And see current transport options replaced with fully electric examples that don't bring with them the plethora of examples outlined in the article!

Just don't hold your breath waiting for calloused indifference to disappear and for sanity to finally prevail!?

the main thing making people in cities sick mentally is foul secular dogmas. Meanwhile life expectancy has increased drastically in the last 50 years.

I thought brain tumours from mobile phones and power lines was supposed to have wiped out our brains? Now I find the real danger is heavy traffic, in London. Oooookay! Although I'm sure there is some sort of statistical link, the author carefully avoids mentioning how significant it is, and how it stacks up against other brain killers - smoking, drugs, alcohol, unsafe sex and so on and on. Difficult to know what to make of it all..

Not difficult at all to follow excellent well documented and peer reviewed research? And just no connection between those well documented studies and the possibility that the magnetic fields of mobile phones, particularly those welded to an ear, may cause brain tumors? Not even the most tenuous connection!

Furthermore, entirely irrelevant to the topic, which happens to be the well documented results of living beside highways, with smokey diesels pounding by day and night!

Hard to know what to make of this published and peer reviewed research? But particularly for the moribund or those accustomed to having others do their critical thinking for them?

Or failing that, tolerate the burning smell emanating from previously unused cerebral circuits?

As per some of our other encounters you completely misunderstood, or chose to misunderstand, what I wrote. I was not challenging the finding the author presents - go back and look at what I wrote - but asking him to place it in context. What does it mean? What are the risks compared to those other, well-documented risks? I note that you also don't seem to know the answers to these questions.

I haven't heard anyone talk about the link between mobile phones and tumours for many years despite the near universal use of such phones. I'm glad you're keeping that story alive. Makes me feel nostalgic.

Come on folks. They obviously have not thought too deeply about this.

Only stupid people live by major roads, if they were not stupid they wouldn't live there. As they age, they don't have to lose too many marbles to start to look like dementia cases.

On second thoughts, the researchers are probably global warming researchers, looking for a new grants gravy train.

About thirty years ago the white coats and clipboard scientists told everyone that diesel was the fuel to use in cities. Cleaner they said, much cleaner than petrol. Well now they have said/found out that particulates are the problem? Now we need to phase out diesel?
Muppett politicians especially of the green sort listened to "SCIENTISTS" with all their peer-reviewed bulltish and helped it all along.
Now I am not saying these scientists are the same people as the global warming we are all going to die variety. I am screaming it!
Let us tax research and researchers and ask for bonds so if you do lie you have to pay for it.

From the food that has preservatives, water polluted from liquid wastes, air polluted by the emission of carbon dioxide, pretty much effects from modern lifestyle of people. Only people also causes all the bad effects to people.

Do come off the grass dogline.

None of these things you're bitching about can be all that bad. After all, life expectancy is almost triple what it was a few thousands of years ago, when everything was totally natural, & totally unpolluted.

It is also double what it was in the middle ages, & about 8 years longer today, than when I was a kid.

Still I don't suppose that people like you would ever admit how well we are doing, especially to yourself.
