On average, Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk , Strayer explained that all this time spent with technology is making our brains tired.
Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain,which, Strayer explains, is important for critical thinking, problem-solving and decision-making.
So, it is important to give the brain a rest. And being in nature , Strayer claims , helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore , swim, sleep, eat and play. Camping may be just what a tired brain needs.
Take Carl for example.He lives in West Virginia and enjoys camping . He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children . She calls it a “regenerative” experience.
At the University of Utah , David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found , it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

Inappropriate calls are a headache for health professionals everywhere.In the US,prank calls to 911 happen on a daily basis.Many callers use apps which hide their identity.But those who try to be funny shouldn’t be surprised if the police
People who take these calls are trained to stay calm and keep a straight face,no matter how strange the call sounds.“There’s no way for us to know whether the call is real,accidental or a prank call,”said a public safety worker interviewed by the American TV channel.
The Head of Clinical Services at the Welsh Ambulance Service,Richard Lee,has a warning for prank callers.He says,“When people misuse the service it means our precious time is being taken away from someone who really does need our help.”Indeed,these hotlines are supposed to help the seriously ill or those with a life—threatening injury.You never know,one day,the person who needs assistance could be you or someone in your family.

When people wanted to find their way to a place in the past,they used to have to buy a map.But they don't have to do that any more.Now they can either buy a GPS,or go online and find maps for just about anywhere.
Is this an improvement?Perhaps,but some people think some of the online companies are going too far,because they have been sending out cars with photographic equipment on their roofs,to photograph every street and house in the country.
One of these cars arrived on a Wednesday morning in the quiet English village of Broughton.The camera was on a meter-high stick an top of the car and could see over walls and into people's gardens.Some of the villagers came and stood around the car,and then asked the driver and photographer to go away.Reporters quickly arrived on the scene,and soon the event was news all over the country.
Of course,the online company in question says that it is simply collecting information that people on the Internet want.But the villagers feel differently."We used to have privacy in this country—now companies just come and take photographs of our home without even asking,"said one villager."It' not right.We mustn't let this happen.We mustn't lose our right to live privately."
There is,of course,no law to prevent people from taking photographs of houses,so the villagers cannot go to court.But many people are asking the question:"OK,it's legal,lout is rt right?"
