A new study shows that air pollution can cause a huge reduction in our intelligence. The study was a project involving researchers at Peking University in China and Yale University in the United States.
The researchers reported that long-term exposure to air pollution can affect a person's mental abilities in two areas: Language and math.
The researchers studied about 25,000 people from across China. Between 2010 and 2014, these Chinese men, women and children were given language and math tests. Then researchers compared the test results with measurements of pollution in the air, namely nitrogen dioxide and sulfur dioxide （二氧化硫）.
Xi Chen of the Yale School of Public Health led the study. He and his team found that breathing polluted air can reduce a person's education level by about one year.
Chen said that the effect generally is worse for those over 64 years of age, for men and for those with little or no education.
“The older persons—they are more affected. And we find, quite amazingly, males are more affected than females. And people working outdoors are more affected than people working indoors.
He noted that the youngest people in the study were 10 years old, while the oldest was 90 years old. They came from China's 33 provinces. In his words, the data and facts are convincing and this range of ages and locations across the country provided a real, objective and representative sample.
The researchers noted that the effect of air pollution on verbal ability is even more serious as people age, especially among men and the less educated. The researchers also stressed that every country, whether developed, developing or poor, should focus on air pollution or humans will face a bad situation.

Some 15 years ago, Ross Willard volunteered with a food program in Harrisburg Pa. He found children riding bicycles with brakes that didn't work. The retired railroad manager saw the importance of safely riding for children, so he began repairing bicycle on street corners.
Over time, more and more people came to have their bicycles repaired. Mr. Willard opened his first shop in 2007 and three years later he founded his own company Recycle Cycle Harrisburg. The all-volunteer nonprofit organization has been offering service for residents in the community. Regular visitors include children and their parents, as well as halfway house residents seeking to perform community service hours while so building their own bikes.
The organization has a do-it-yourself philosophy: Although there is no charge for any repair, or even bicycles, most visitors( except young children)are tasked with making their own repairs with the assistance of volunteer trainers.
Since its founding, Recycle Bicycle has distributed thousands of donated bikes to the Harrisburg community averaging about 900 per year in the past decade. He's known as “Mr. Bicycle, around the Pennsylvania capital. He estimates that the organization repairs some 3,000 bikes a year.
Sitting in the organization’s shop space, he discusses the volunteerism and sense of service that were imprinted on him as a child by his parents. This led to a strong belief about fixing problems that one finds in the community.

The 1972 Hawaii episodes opened the fourth season of The Brady Bunch, and they have become a beloved part of pop culture. Here are the top places where the Hawaii episodes of The Brady Bunch were filmed.
Sheraton Waikiki
Location: 2255 Kalakaua Avenue, Honolulu, Hawaii 96815
The entrance to the Sheraton Waikiki has not changed all that much. All of its original charm remains. You can even book an ocean-view room like the Brady family would have enjoyed. Be sure to also check out the breathtaking infinity pool.
Halona Blowhole Lookout
Location: 8483 Highway 72, Honolulu, Hawaii 96825
During their tour of Hawaii, the Bradys looked in the wonder at the still-active Halona Blowhole. It's one of Hawaii's many natural wonders. The rock formation and blowhole shoots ocean water spray high into the air when the waves roll in.
Although there are no active volcanoes on Oahu now, their effects on the island linger. The best time to come here is when winds are strong and the tide is high.
View Rabbit Island from Makapu'u Beach Park
Location:41-095 Kalanianaole Highway, Makapu'u Point, Hawaii 96795
The Brady girls enjoyed the view of Rabbit Island. Although it's referred to by its nickname in the episodes, the real name of Rabbit Island is Manana Island. It got its nickname because many rabbits used to inhabit the area. It's now an uninhabited islet on the eastern end of Oahu.
Hula dancing on the Ocean Lawn of the Royal Hawaiian
Location: 2259 Kalakaua Avenue, Honolulu, Hawaii 96815
