Walkable cities reduce blood pressure and hypertension risk

A study of the link between city walkability and blood pressure, the largest ever conducted, has been held up as evidence of the "intangible value of urban design" in improving long-term health outcomes, said researchers.

The study of about 430,000 people aged between 38 and 73 and living in 22 British cities found significant links between a neighbourhood's increased walkability, lower blood pressure and reduced hypertension risk among its residents.

The outcomes were consistent even after adjustments for socio-demographic, lifestyle and physical environment variables, though the protective effects were particularly pronounced among participants aged between 50 and 60, women, and those residing in higher density and deprived neighbourhoods.


Technology: Cars with keyless entry system are easy theft targets

Owners of cars using the keyless entry system are at risk of having their vehicles stolen in minutes by a frequency-hacking device that is easily available for about RM150 (S$50) and can be obtained online or at some electronics stores, can unlock a car and start its engine by hacking its radio frequency identification (RFID) information.

A source said the device can open almost every car that has a keyless entry system.

Munich-based Allgemeiner Deutscher Automobil-Club (Adac), the largest auto club in Europe, recently said 110 models from 27 different manufacturers were at risk of being stolen based on the keyless system they used.

Car owners should take extra precautions like installing GPS tracking devices or use steering or gear locks to deter thieves," said a Malaysian police spokesman, adding that nothing beats a good physical lock, which made it much harder for thieves.
