Just one hour a week of brisk walking may prevent disability in older adults with arthritis pain, or aching or stiffness in the knee, hip, ankle or foot, a new study suggests.

The findings suggested that an hour of weekly moderate-to-vigorous physical activity allowed older adults to maintain their ability to perform daily tasks like getting dressed or cross a street before a traffic light walk signal changed.


“This is less than 10 minutes a day for people to maintain their independence. It’s very doable,” said lead author Dorothy Dunlop, Professor at the Northwestern University Feinberg School of Medicine in the US.

“This minimum threshold may motivate inactive older adults to begin their path toward a physically active lifestyle with the wide range of health benefits promoted by physical activity,” Dunlop added.

For the study, published in the American Journal of Preventive Medicine, the researchers analyzed four years of data from more than 1,500 adults.

The adults all had pain, aching or stiffness in lower extremity joints from osteoarthritis but were free of disability when they began the study. Their physical activity was monitored using accelerometers.

The team found that the weekly hour of exercise reduced their risk of mobility disability by 85 per cent and their risk of activities of daily living disability by almost 45 per cent.

Four years after the start of the study, 24 per cent of adults who did not get the weekly hour of brisk physical activity were walking too slowly to safely cross the street, and 23 per cent reported problems performing their morning routine.

“Our goal was to see what kind of activity would help people remain free of disability,” the lead author said.

“We hope this new public health finding will motivate an intermediate physical activity goal.” (IANS)

Delhi to get new QR-based driving livenses and registration certificates.

In a step towards digitisation of the system, Delhi Transport Department will soon issue QR based Smart cards for driving licenses (DLs) and registration certificates (RCs).

As per a statement, the new driving licence will have an advanced microchip with features like Quick Response (QR) code and Near Field Communication (NFC). The new RC will have the owner's name printed on the front while the microchip and the QR code would be embedded at the back of the card.

The cards earlier had embedded chips, but chip reader machines were not available in the required quantity with both the Delhi Traffic Police and the Enforcement Wing of the Transport Department. Moreover, chips were designed and implemented by the states concerned, which resulted in difficulties in reading the chip and retrieving information, especially in case of defaulters.

"Now with the QR based smart card, this issue is resolved. This will enable unification in linking and validating one's information to smart cards with Sarathi and Vahan, the two web-based databases of all driving licenses and vehicle registrations," the release added.

The QR is also being implemented nationwide, the QR code reader is easily procurable and will do away with the requirement of any manual intervention altogether. The new cards will also allow two specific materials for their card manufacturing -- PolyVinyl Chloride or PVC, or PolyCarbonate which is slightly more expensive but more durable. (Card Size - 85.6mm x 54.02 mm; Thickness minimum 0.7 mm)

An October 2018 notification of the Ministry of Road Transport and Highways (MoRTH) had made changes to the Driving License and Registration Certificate. The new Smart card based DL and RC, will have chip based/ QR code based recognition system. At the same time, documents such as driving license or registration certificates in electronic formats on DigiLockers and mParivahan were also made valid in place of physical documents and treated at par with original documents.

The QR code also has an added advantage of acting as a safety feature on the smart card. The department will be able to retain records and penalties of the DL holder for up to 10 years on the VAHAN database as soon as a driver/ owner's Smart card is confiscated. The new DLs will also help the government in maintaining records of differently-abled drivers, any modifications made to the vehicles, emission standards and the person's declaration to donate organs.

LONDON — A work by British street artist Banksy that sensationally shredded itself just after it sold at auction three years ago fetched almost 18.6 million pounds ($25.4 million) on Thursday — a record for the artist, and close to 20 times its pre-shredded price.

"Love is in the Bin" was offered by Sotheby's in London, with a presale estimate of 4 million pounds to 6 million pounds ($5.5 million to $8.2 million).
