Middle-aged people are being encouraged to walk faster to help stay healthy, amid concern high levels of inactivity may be harming their health.
Public Health Officials in England said the amount of activity people did started to tail off from the age of 40.
They say just 10 minutes a day could have a major impact, reducing the risk of early death by 15%. But estimates four out of every 10 40- to 60-year-olds do not even manage a brisk 10-minute walk each month,they say.
To help, the government agency is promoting a free app -Active 10- which can monitor the amount of brisk walking an individual does and provide tips on how to incorporate more into the daily routine.
