>QR codes replace menus

The coronavirus pandemic ushered in the widespread use of QR codes, but restaurant industry experts think that the technology will stick around long after the health crisis ends. 

Bitly, a link management service, said that it"s seen a 750% increase in QR code downloads over the last 18 months. 

A QR code also gives restaurants more information on their customers. 

Reservation services pass along data on whoever made the booking to restaurants – but not everyone else at the table. 

What the QR code might allow you to do is learn who that guest is right when they"re sitting down. 

However, QR codes aren"t the answer for all restaurants. 

Darren Seifer, food and beverage analyst for the NPD Group, said that fine-dining restaurants are less willing to replace their menus or ordering process with QR codes.


>Mentally stimulating job cuts risk of dementia

Having an interesting job in your 40s may slash your risk of getting dementia in old age, a study suggested. 

Researchers claim mental stimulation may stave off the onslaught of the memory-robbing condition by around 18 months. 

Academics examined more than 100,000 participants and tracked them for nearly two decades. 

They spotted a third fewer cases of dementia among people who had engaging jobs that involved demanding tasks and more control — such as solicitors and doctors, compared to adults in "passive" roles - such as cashiers. 

And those who found their own work interesting also had lower levels of proteins in their blood that have been linked with dementia. 

Keeping the brain active by challenging yourself regularly likely reduces the risk of dementia by building up its ability to cope with disease, experts say.


>"Drunk driving" of elephants banned 

Sri Lanka will issue captive elephants with their own biometric identity cards and ban their riders from drinking on the job under a new animal protection law. 

The new measures are aimed at protecting the animals" welfare and include strict regulations around working elephants, as well as mandating a daily two-and-a-half-hour bath for each creature. 

Baby elephants can no longer be used for work -- even cultural pageants -- and cannot be separated from their mothers. 

Logging elephants cannot be worked for more than four hours a day, and night work is prohibited.

There are new restrictions on the tourism industry too -- from now on, no more than four people can ride an elephant at once. 旅游业也受到了新的限制,从现在开始,同时骑象者不能超过四人。

Owners must send their animals for a medical check-up every six months. 

Those who violate the new law will have their elephant taken into state care and could face a three-year prison sentence.


>A third of adults suffer from high blood pressure

A giant global study finds the number of people over 30 with high blood pressure has doubled over the past 30 years, and more than half of them are not being treated for it. 

The researchers looked at data covering 184 countries. The number of people with high blood pressure doubled from 648 million in 1990 to nearly 1.3 billion by 2019, they found. 

Overall, just under a third of men and women ages 30 to 79 had high blood pressure, the study found. 

"The pandemic of cardiovascular disease has received less attention in the last 18 months but reflects concerning worldwide trends in unhealthy lifestyle choices such as high fat, sugar, salt and alcohol intake, sedentary lifestyles with avoidance of exercise, and smoking," said Robert Storey, a professor of cardiology at the University of Sheffield.
