Breathing polluted air every day may change a person's brain in ways that end up leading to cognitive impairment, according to a new study.
In the study, researchers examined 943 healthy adults who were at least 60 years old and lived the New England region. The investigators used magnetic resonance imaging (MRI) to look at the participants' brain structures, and compared the images with the air pollution levels in the places where the participants lived.
The researchers found that an increase of 2 micrograms per cubic meter in fine-particle pollution — a range that can be observed across an average city — was linked to a 0.32 percent reduction in brain volume. (Fine-particle pollution is a common type of pollution that comes from car exhaust, among other sources.)
That amount of change in brain volume "is equivalent to about one year of brain aging," said study author Elissa H. Wilker, a researcher in the cardiovascular epidemiology research unit at Beth Israel Deaconess Medical Center in Boston.
In general, a smaller brain volume is caused by the loss of neurons that comes with aging, the researchers said.

Now ya know.
All that hyperventilating increases their pollution intake and shrinks their brains.
‘Twould be more logical to conclude that reading Yahoo news shrinks the brain.
I may have to start a study on you,, or find new places to post stuff from, ;-)
All of the ancient peoples must have had tiny brains after breathing in all that cooking and heating smoke.
I guess using dung for heat and cooking is a significant factor in the advancement of peoples or rather why they don’t advance.
It could work either way. Either Global Warming shrinks the brain, or shrunken brains believe in Global Warming.
If you look t the detailed maps of the past several elections, you’ll note that the urban areas are deep-blue democrat, and the rural areas tend to be Republican red.
The Southern and Western states, except the coastal areas of California, Portland and Seattle tend to also be red.
Rural = red = Republican = less pollution = bigger brains.
Conversely, big city = blue = democrat = pollution = shrunken brains.
I rest my case, your honor!
I suggest that studies like these shrink the brain.
This explains Los Angeles.
partially.....
Oh. Like smoking choom.

The libs arguments always backfire.
