Brisk walking cuts heart risk

Brisk walks can reduce the risk of a heart attack or stroke by half, research has found.

Scientists say it is the intensity rather than the duration of the exercise that counts, while an hour's daily walk makes little difference.

The research, published in the online health journal BMJ Open, found that daily fast walks cut the risk factors for strokes and heart problems by 50pc, while jogging reduced them by 40pc.

The study looked at the health of more than 10,000 Danish residents between the ages of 21 and 98, who were monitored for 10 years.



North Korea in



missile threat

North Korea says South Korea, Japan, Guam and the US mainland are within range of its missiles.

The National Defence Commission issued the statement in response to South Korea's recent announcement that the US agreed to let it have longer-range missiles capable of hitting all of North Korea.

It is unusual for North Korea to say its missiles are capable of striking the US, but the country has regularly issued harsh rhetoric against Washington.

The two governments are working on a project to wipe out the disease on Hispaniola by 2022. The plan will include substantial spending on clean water and sanitation, following more than 7,000 deaths since 2010.
